The interest for compact antennas in wireless communication increase due to
the portability and mobility of the communication devices. Generally, an
antenna at low frequency exhibits in large physical size. This project
investigates the design of an antenna at 400 MHz. The simulation of the
antenna has been performed using CST MWS. Since medical applications are
dealing with low frequency, it will lead to large size of antenna which brings
a challenge for wireless personal area network (WPAN). It is well known
that the antenna performance decreases (according to Chu’s equation) as the
size of antenna decreases. Therefore, antenna miniaturization using Meander
Line (ML) will be taking place to overcome the challenges. Thus, this paper
presents a comparison between i) printed dipole antenna without meander
line technique, ii) printed dipole with meander line technique and iii) printed
monopole antenna with meander line technique. The results show that an
estimation of reduction size by 50% can be achieved using Meander
Line technique.

1. INTRODUCTION
Miniaturization of wireless communication system have been favourable in conjunction with the
high demand for small or compact equipment. Antenna also has no exemption. Small is defined in many
ways. However, antenna is designed for the sake of comparison. Often, the antenna that has been reduced in
size not compatible with their performance. To design a small antenna for low frequency in conventional
method resulting in a large size of antenna. At low operating frequency, the issues comes in terms of it sizes
as the antenna sizes affects the systems and portability [1].
The antenna is involved in many wireless electronic devices with a different kind of size. The
attraction to the small antenna in this era increase due to fast-growth in an industry of mobile
communications [2]. The demand not only involved the small size of an antenna, but the better performance
and efficiency also must be considered in designing an antenna. However, due to the fundamental limitations
in size and performance (Chu’s limit), achieving miniaturization with good antenna performance is
challenging. Electrically small antennas (ESAs) are limited in bandwidth and radiating efficiency. Thus, this
factor should be taken into account when designing an antenna.
A small antenna can be defined in different wavelengths such as one-quarter wavelength (1/4),
one-eight wavelength (1/8) or one-tenth wavelength (1/10). Not only that, it also can be defined in term of
electrical size. A small antenna in electrical size or volume described by the value of ka where k is

wavenumber of 2π/λ in free space and a is a radius of sphere in an imaginary circumscribing the maximum
dimension of the antenna.
On the other hand, the miniaturization of antenna can be observed in a few methods. There are
meander line techniques, fractals and using metamaterial. Each technique comes with its own advantages and
disadvantages. Meander line was applied to increase the electrical length of the antenna as in [3] while fractal
is proven to design antenna with multiband, wideband as well as to reduce the antenna size [2]. For
metamaterial, multiband frequency can be achieved as well as reduce the antenna size as in [4].
Meander-line antenna concept is to fold the conductors back and forth in order to produce a compact
antenna with shorter length. The limitation of the area size for antenna placement brings challenge to the
antenna designer. Thus, other than using the structure of meander-line to the antenna itself, it is also has been
implemented at the reactive impedance surface (RIS) of the metallic ground of the antenna as in [5]. This
technique allows size reduction of 25%-50% of the antenna original size. By using meander-line design,
antenna can be operated at low frequency such as at 315 MHz [6]. Meander line antenna is used as from [7],
a half wavelength dipole is made compact by meandering the wire [8]. Same approach can be applied to
design a meander-type slot antenna for size reduction up to 80% [9-10]. Other than that, meandering the
excited patch surface current paths in the microstrip antenna’s radiating patch is also an effective method for
achieving a lowered fundamental resonant frequency for the microstrip antenna [11-15]. From this fact,
meander type antenna has some advantages such as compact size/small, easily integrated into wireless
devices, and low cost implementation [16]. Miniaturization method of printed meander-line is used in the
design. Printed antennas has been favoured because it is able to minimize the space, light weight, and
minimum cost required for the production. For the past twenty years ago, printed antenna features was
studied and evolved until today [1, 16-17]. On the other hand, Meander Line techniques has been applied in
telemetry applications [18].
It is well known that electrically small antennas suffers the fundamental limit of high Q and can not
be used for broadband radiation in conventional cases. It is highlighted that as the antenna size decreases,
antenna performance such as bandwidth and efficiency will be affected due to the Q’s formula as in (1).
( )
(1)
Q refers to quality factor and high Q refers to narrowband antenna. As the size of antenna ka
decreases, Q values will increase thus leading to a narrow bandwidth antenna.
In this paper, a few design of printed antennas with a meander line technique at 400 MHz is
simulated and fabricated to study its performance. This paper proposed three antenna designs which are
printed dipole antenna (without Meander-Line), printed dipole antenna (with Meander-Line [19]) and
monopole antenna (with Meander-Line). The objective is to investigate the size that can be reduced from the
normal design using miniaturization technique and compare their performance. The operating frequency is at
400 MHz. The following section will discuss the antenna design consideration and some simulated and
measurement results e.g. return loss (S11), bandwidth, and radiation pattern.
2. RESEARCH METHOD
2.1. Printed dipole antenna
Simulation of a printed dipole antenna (without meander line) was performed in CST MW. The
proposed antennas are printed on a FR-4 substrate as the material with dielectric constant is 4.3 and thickness
of 1.6 mm. The antennas were modeled using copper (annealed) which is a lossy material. Copper (annealed)
is chosen as it corresponds with the practical antenna so the results will be presented close to actual values.
The printed dipole is fed with the gap G between the two dipole arms. In this case, the suitable gap
G has been chosen. This antenna was simulated for the comparison of its performance and the resulting size
observed. It is observed that from the printed dipole antenna design at 400 MHz as shown in Figure 1 and 2,
the size is quite high which is around (44 cm x 16 cm). Therefore, a meander line technique has been
proposed to reduce the size of printed dipole antenna. The dimension is shown in Table 1.

2.2. Printed dipole antenna with meander line technique
Simulation of a printed dipole antenna with Meander-Line technique is applied for miniaturization
process. The length of dipole antenna is folded back and forth in order to reduce the dipole arm’s length.
Using the dimensions in Table 2, a printed dipole antenna of meander line (ML) technique at 400 MHz has
been designed using CST as shown in Figure 2 and Figure (a) and (b). It is observed that the size of meander
line printed dipole antenna has been reduced to 24 cm x 12 cm which is approximately reduced to half from
the initial design of printed dipole antenna as shown in Figure 1.

2.3. Printed monopole antenna with meander line technique
The monopole meander line antenna has been designed from the second simulation of meander line
dipole antenna in section 2.1.2. As we want the antenna design to be smaller in size, therefore monopole
antenna is considered in this case. The design initially taken from one side of the meander dipole arm. Thus,
making the design exhibits as monopole. Monopole antenna are half size of the dipole antenna. The different
of monopole antenna is that the design is mounted above some sort of ground plane that acts as a dipole due
to the reflections. A printed meander line monopole antenna designed at 400 MHz (Figure 3(a) and (b)) has
been designed with the dimension shown in Table 3. It is observed that the size has been reduced to 13.65 cm
x 2.7 cm which is much smaller than Figure 2.

3. RESULTS AND ANALYSIS
3.1. Simulation results
Figure 4 shows that each antenna design (design A, B and C) has the ability to resonate at 0.4 GHz.
From the simulated data, by miniaturizing the antenna size, we can obtain a good antenna performance by
using meander-line technique. The comparison of simulation results from three antenna designs are shown in
Table 4. In our design, all the return loss (S11) values are higher than 10 dB. Printed dipole (without
ML-design A) shows return loss value of 40.22 dB, printed dipole (with ML-design B) is 19.6 dB and
monopole (with ML-design C) is 11.88 dB. In terms of the antenna size, third antenna exhibits smaller size
(13.65cm x 2.7cm) compared to first (44cm x 16cm) and second antenna (24.8cm x 1.2cm). The third
antenna exhibits nearly 75% reduction in comparison with the second (50% reduction) based on the first
design. However, the return loss decreased as the antenna size decreased. It is due to the electrically size
decrease the radiation resistance and resulting to lower value of return losses as in Figure 4.
In terms of bandwidth, the results exhibit the same behavior which is the largest bandwidth is
obtained from printed dipole antenna (22%), followed by printed meanderline dipole antenna (8.2%) and the
smallest bandwidth is the printed meanderline monopole antenna (2.1%). It is in accordance to the theory of
Chu’s limit that as antenna size decreases, the Q factor increases which lead to low bandwidth of the antenna.
Figure 5 and 6 shows the combination of all three simulated design radiation pattern in
two-dimensional pattern. It is observed that the pattern is circular shape (omni-directional) on the azimuth
plane (phi=90) as well as eight-shape pattern on the elevation plane (theta=90). The radiation pattern for all
the antenna shows (omni-directional) pattern where the radiating energy is almost the same in all directions
in that plane.

3.2. Measurement results
Design of B and C have been fabricated in order to validate the S11 performance of the simulation
design. The designs as shown in Figure 7 and 8 were measured using Vector Network Analyser and the
comparison between simulation and measurement results have been plotted in Figure 9. Table 5 summarizes
the perofmance of both designs. It was observed that Design B has a close agreement between simulation and
measurement results in comparison with Design C. One of the disagreements of Design C is due to the fact
that it is fabricated manually, from film printing, patching, UV exposure, etching, cutting and finishing
process which lead to the inaccuracies of the design. Thus, Table 5 illustrated the comparison of simulation
and measurement results between design B and C.

4. CONCLUSION
The miniaturization antenna using Meander Line (ML) technique has been performed and
investigated in detail. This research investigates on how much antenna size can be reduced using Meander
Line (ML) technique and at the same time able to resonate at the required frequency. The simulated results
shows that the three proposed design are able to operate at the desired frequency of 400 MHz. Based on the
S11, it is observed that as the antenna size reduces, the antenna performance decreases especially in terms of
return loss and bandwidth according to Chu’s equation.
Thus, based on the S11 results, design B of printed dipole and design C of printed monopole
antennas (with ML) were fabricated to validate the antenna performances. Design C was fabricated manually
leading to inaccuracies between simulation and measurement results. Although the fabricated antenna with
the simulated both did not agree with one another due to the losses, tolerance as well as fabrication error
when constructing the antenna, it can be seen that using Meander Line the antenna size can be reduced.
For the further improvement, the antenna size can be further decreased using other miniaturization
techniques. Other types of miniaturization technique can be reviewed in depth in order to have an antenna
with compact size and good performance at low frequency.

Generally, an antenna at low frequency exhibits in large physical size. This project investigates the design of an antenna at 400 MHz. The simulation of the antenna has been performed using CST MWS. Since medical applications are dealing with low frequency, it will lead to large size of antenna which brings a challenge for wireless personal area network (WPAN). It is well known that the antenna performance decreases (according to Chu’s equation) as the size of antenna decreases. Therefore, antenna miniaturization using Meander Line (ML) will be taking place to overcome the challenges. Thus, this paper presents a comparison between i) printed dipole antenna without meander line technique, ii) printed dipole with meander line technique and iii) printed monopole antenna with meander line technique. The results show that an estimation of reduction size by 50% can be achieved using Meander Line technique.

Antenna also has no exemption. Small is defined in many ways. However, antenna is designed for the sake of comparison. Often, the antenna that has been reduced in size not compatible with their performance. To design a small antenna for low frequency in conventional method resulting in a large size of antenna. At low operating frequency, the issues comes in terms of it sizes as the antenna sizes affects the systems and portability [1]. The antenna is involved in many wireless electronic devices with a different kind of size. The attraction to the small antenna in this era increase due to fast-growth in an industry of mobile communications [2]. The demand not only involved the small size of an antenna, but the better performance and efficiency also must be considered in designing an antenna. However, due to the fundamental limitations in size and performance (Chu’s limit), achieving miniaturization with good antenna performance is challenging. Electrically small antennas (ESAs) are limited in bandwidth and radiating efficiency. Thus, this factor should be taken into account when designing an antenna. A small antenna can be defined in different wavelengths such as one-quarter wavelength (1/4), one-eight wavelength (1/8) or one-tenth wavelength (1/10). Not only that, it also can be defined in term of electrical size. A small antenna in electrical size or volume described by the value of ka where k is

On the other hand, the miniaturization of antenna can be observed in a few methods. There are meander line techniques, fractals and using metamaterial. Each technique comes with its own advantages and disadvantages. Meander line was applied to increase the electrical length of the antenna as in [3] while fractal is proven to design antenna with multiband, wideband as well as to reduce the antenna size [2]. For metamaterial, multiband frequency can be achieved as well as reduce the antenna size as in [4]. Meander-line antenna concept is to fold the conductors back and forth in order to produce a compact antenna with shorter length. The limitation of the area size for antenna placement brings challenge to the antenna designer. Thus, other than using the structure of meander-line to the antenna itself, it is also has been implemented at the reactive impedance surface (RIS) of the metallic ground of the antenna as in [5]. This technique allows size reduction of 25%-50% of the antenna original size. By using meander-line design, antenna can be operated at low frequency such as at 315 MHz [6]. Meander line antenna is used as from [7], a half wavelength dipole is made compact by meandering the wire [8]. Same approach can be applied to design a meander-type slot antenna for size reduction up to 80% [9-10]. Other than that, meandering the excited patch surface current paths in the microstrip antenna’s radiating patch is also an effective method for achieving a lowered fundamental resonant frequency for the microstrip antenna [11-15]. From this fact, meander type antenna has some advantages such as compact size/small, easily integrated into wireless devices, and low cost implementation [16]. Miniaturization method of printed meander-line is used in the design. Printed antennas has been favoured because it is able to minimize the space, light weight, and minimum cost required for the production. For the past twenty years ago, printed antenna features was studied and evolved until today [1, 16-17]. On the other hand, Meander Line techniques has been applied in telemetry applications [18]. It is well known that electrically small antennas suffers the fundamental limit of high Q and can not be used for broadband radiation in conventional cases. It is highlighted that as the antenna size decreases, antenna performance such as bandwidth and efficiency will be affected due to the Q’s formula as in (1). ( ) (1) Q refers to quality factor and high Q refers to narrowband antenna. As the size of antenna ka decreases, Q values will increase thus leading to a narrow bandwidth antenna. In this paper, a few design of printed antennas with a meander line technique at 400 MHz is simulated and fabricated to study its performance. This paper proposed three antenna designs which are printed dipole antenna (without Meander-Line), printed dipole antenna (with Meander-Line [19]) and monopole antenna (with Meander-Line). The objective is to investigate the size that can be reduced from the normal design using miniaturization technique and compare their performance. The operating frequency is at 400 MHz. The following section will discuss the antenna design consideration and some simulated and measurement results e.g. return loss (S11), bandwidth, and radiation pattern. 2. RESEARCH METHOD 2.1. Printed dipole antenna Simulation of a printed dipole antenna (without meander line) was performed in CST MW. The proposed antennas are printed on a FR-4 substrate as the material with dielectric constant is 4.3 and thickness of 1.6 mm. The antennas were modeled using copper (annealed) which is a lossy material. Copper (annealed) is chosen as it corresponds with the practical antenna so the results will be presented close to actual values. The printed dipole is fed with the gap G between the two dipole arms. In this case, the suitable gap G has been chosen. This antenna was simulated for the comparison of its performance and the resulting size observed. It is observed that from the printed dipole antenna design at 400 MHz as shown in Figure 1 and 2, the size is quite high which is around (44 cm x 16 cm). Therefore, a meander line technique has been proposed to reduce the size of printed dipole antenna. The dimension is shown in Table 1.

Printed dipole antenna with meander line technique Simulation of a printed dipole antenna with Meander-Line technique is applied for miniaturization process. The length of dipole antenna is folded back and forth in order to reduce the dipole arm’s length. Using the dimensions in Table 2, a printed dipole antenna of meander line (ML) technique at 400 MHz has been designed using CST as shown in Figure 2 and Figure (a) and (b).

Printed monopole antenna with meander line technique The monopole meander line antenna has been designed from the second simulation of meander line dipole antenna in section 2.1.2. As we want the antenna design to be smaller in size, therefore monopole antenna is considered in this case. The design initially taken from one side of the meander dipole arm. Thus, making the design exhibits as monopole. Monopole antenna are half size of the dipole antenna. The different of monopole antenna is that the design is mounted above some sort of ground plane that acts as a dipole due to the reflections. A printed meander line monopole antenna designed at 400 MHz (Figure 3(a) and (b)) has been designed with the dimension shown in Table 3. It is observed that the size has been reduced to 13.65 cm x 2.7 cm which is much smaller than Figure 2. (a) (a) Figure 3.

RESULTS AND ANALYSIS 3.1. Simulation results Figure 4 shows that each antenna design (design A, B and C) has the ability to resonate at 0.4 GHz. From the simulated data, by miniaturizing the antenna size, we can obtain a good antenna performance by using meander-line technique. The comparison of simulation results from three antenna designs are shown in Table 4. In our design, all the return loss (S11) values are higher than 10 dB. Printed dipole (without ML-design A) shows return loss value of 40.22 dB, printed dipole (with ML-design B) is 19.6 dB and monopole (with ML-design C) is 11.88 dB. In terms of the antenna size, third antenna exhibits smaller size (13.65cm x 2.7cm) compared to first (44cm x 16cm) and second antenna (24.8cm x 1.2cm). The third antenna exhibits nearly 75% reduction in comparison with the second (50% reduction) based on the first design. However, the return loss decreased as the antenna size decreased. It is due to the electrically size decrease the radiation resistance and resulting to lower value of return losses as in Figure 4. In terms of bandwidth, the results exhibit the same behavior which is the largest bandwidth is obtained from printed dipole antenna (22%), followed by printed meanderline dipole antenna (8.2%) and the smallest bandwidth is the printed meanderline monopole antenna (2.1%). It is in accordance to the theory of Chu’s limit that as antenna size decreases, the Q factor increases which lead to low bandwidth of the antenna. Figure 5 and 6 shows the combination of all three simulated design radiation pattern in two-dimensional pattern. It is observed that the pattern is circular shape (omni-directional) on the azimuth plane (phi=90) as well as eight-shape pattern on the elevation plane (theta=90). The radiation pattern for all the antenna shows (omni-directional) pattern where the radiating energy is almost the same in all directions in that plane.

Measurement results Design of B and C have been fabricated in order to validate the S11 performance of the simulation design. The designs as shown in Figure 7 and 8 were measured using Vector Network Analyser and the comparison between simulation and measurement results have been plotted in Figure 9. Table 5 summarizes the perofmance of both designs. It was observed that Design B has a close agreement between simulation and measurement results in comparison with Design C. One of the disagreements of Design C is due to the fact that it is fabricated manually, from film printing, patching, UV exposure, etching, cutting and finishing process which lead to the inaccuracies of the design. Thus, Table 5 illustrated the comparison of simulation and measurement results between design B and C. Table 5.

CONCLUSION The miniaturization antenna using Meander Line (ML) technique has been performed and investigated in detail. This research investigates on how much antenna size can be reduced using Meander Line (ML) technique and at the same time able to resonate at the required frequency. The simulated results shows that the three proposed design are able to operate at the desired frequency of 400 MHz. Based on the S11, it is observed that as the antenna size reduces, the antenna performance decreases especially in terms of return loss and bandwidth according to Chu’s equation. Thus, based on the S11 results, design B of printed dipole and design C of printed monopole antennas (with ML) were fabricated to validate the antenna performances. Design C was fabricated manually leading to inaccuracies between simulation and measurement results. Although the fabricated antenna with the simulated both did not agree with one another due to the losses, tolerance as well as fabrication error when constructing the antenna, it can be seen that using Meander Line the antenna size can be reduced. For the further improvement, the antenna size can be further decreased using other miniaturization techniques. Other types of miniaturization technique can be reviewed in depth in order to have an antenna with compact size and good performance at low frequency.
