ABSTRACT
Small antennas satisfying bandwidth requirements in wideband, broadband and multichannel
communication systems are of wide interest among researchers. This paper investigates the
resonant behaviour of proximity coupled circular fractal planar monopole against circular
fractal planar monopole without proximity coupling. The antennas are fed using microstripline
and coplanar waveguide technique. These antennas are designed and printed on low cost FR4
substrate ( height h=1.56mm and εr =4.3) of size 110 mm by 115 mm with circular patch radius
of 40 mm. The planar fractal monopole shows multiband characteristics under different
configurations of feed. The monopole can be used for various compact
applications in 482 MHz to 4 GHz band.

ABSTRACT
Slot antenna is designed with microstrip feed line for Wireless Local Area Network (WLAN)
applications. The first patch is designed as a rectangular shape and the other is designed as an
inverted L shape. The antenna is printed on a FR4 substrate with a thickness of 0.8mm and
relative permittivity of 4.6.The resulting antenna is found to have a compact size of
22.75x22mm2. It offers dual band characteristics with -10dB return loss and it radiates in
omnidirectional pattern. The antenna receives RF signals which are converted into DC power
by connecting it through the matching circuit, rectifier and voltage multiplier.Matching circuit
is needed for matching the impedance of the antenna and the impedance of the rectifier.
Rectifier uses schottky diode (HSMS 2850) which has high switching speed and low forward
voltage convert the input RF signal received by the antenna into suitable DC supply voltage.
The produced DC voltage can be doubled by using voltage doubler. The output power from the
voltage doubler is given to low power devices for charging. These designs are simulated by
using ADS 2011 (Advanced DesignsSystem) software.

ABSTRACT
There are various patch antennas used for Wi-Fi and Wi-MAX applications. But, the
problems with them are low gain, low power handling capacity and hence,
conventional yagi-uda antennas are used. Conventional yagi-uda antennas are used in
applications where high gain and directionality are required. Generally, numbers of
directors are added to increase gain of these antennas. But, here we present modified
yagi-uda antennas, in which the gain and bandwidth can be enhanced by not adding
additional directors.
In this paper, we initially discuss the designs of various yagi-uda antennas with
uniform, non-uniform spacings between directors and then we discuss their gain and
bandwidth enhancement by various approaches. Simulation results show that, the
proposed techniques can enhance gain as well as bandwidth when compared with the
traditional yagi-uda antennas.

ABSTRACT
High-accuracy Global Navigation Satellite System (GNSS) positioning is a prospective
technology that will be used in future automotive navigation systems. This system will be a
composite of the United States' Global Positioning System (GPS), the Russian Federation's
Global Orbiting Navigation Satellite System (GLONASS), China Beidou Navigation
Satellite System (BDS) and the European Union’s Galileo. The major improvement in
accuracy and precision is based on (1) multiband signal transmitting, (2) carrier phase
correction, (3) Real Time Kinematic (RTK). Due to the size and high-cost of today’s survey-
grade antenna solutions, this kind of technology is difficult to use widely in the automotive
sector. In this paper, a low-cost small size dual-band ceramic GNSS patch antenna is
presented from design to real sample. A further study of this patch antenna illustrates the
absolute phase center variation measured in an indoor range to achieve a received signal
phase error correction. In addition, this low-cost antenna solution is investigated when
integrated into a standard multi-band automotive antenna product. This product is evaluated
both on its own in an indoor range and on a typical vehicle roof at an outdoor range. By
using this evaluation file to estimate the receiver position could achieve phase motion error-
free result.

ABSTRACT
A triple rectangular slotted microstrip patch antenna is designed and investigated with and
without slot using CST Software. By using the triple rectangular shaped slot the designed
antenna operates at 2.4GHz (ranging from 2.3704 GHz (Gigahertz) to 2.4391 GHz at -10dB
return loss) for WLAN (Wireless Local Area Network) and 3.6GHz (ranging from 3.5643
GHz to 3.6548 GHz at -10dB return loss) for WiMAX (Worldwide Interoperability for
Microwave Access) applications having a maximum return loss -28.5dB and -25.4dB
respectively. For the design of this antenna we have chosen FR-4 (lossy) as substrate having
permittivity 4.3. The designed antenna has appreciable values of gain and directivity at both
the frequencies. The proposed antenna works on the principle of excitation of the slots at the
operating frequencies. The antenna was designed keeping in mind the two major Wireless
standards i.e., WLAN and WiMAX bands of frequencies. The proposed triple-rectangular
slots are unique in terms of its construction and have appreciable results at the operating
frequencies.

ABSTRACT
In this paper dual band Planar Inverted F Antenna (PIFA) is presented for mobile handset
applications at dual frequencies. PIFA is a flat structure, simple and easy to fabricate. The
idea of U-shaped slot technique is introduced into the basic rectangular patch antenna for
higher GSM frequency. The impedance bandwidth covers GSM 900 and GSM 1900 bands.
The PIFA covers a bandwidth of 31.9MHz (0.88-0.911GHz) or about 3.5% with respect to
the resonance frequency at 0.89GHz. For the higher resonant mode the impedance bandwidth
is 112.7MHz (1.873-1.985GHz) or about 5.83% with respect to resonance frequency of 1.93
GHz. The PIFA has a gain of 2.59dB and 5.12dB at lower and higher resonating frequencies
respectively. PIFA is analyzed using High Frequency Structure Simulator (HFSS).

ABSTRACT
A Microstrip Patch Antenna is a type of radio antenna with a low profile, which can be
mounted on a low surface. It is a narrow band, wide-beam fed antenna fabricated by etching
the antenna element pattern in metal trace bonded to the dielectric Substrate such as a printed
circuit board with a continuous metal layer bonded to the opposite side of the substrate which
forms a ground plane. The main aim of this work is to design, develop and test the Printed
Circuit antenna (Microstrip Patch antenna) suitable for use in L-band frequency range of 1-
2GHz. This study also emphasizes on simulation of micro-strip patch antenna using IE3D
software to simulate & study the radiation pattern & other radiation pattern parameters and
comparison with specifications/requirements. Co-axial Feed technique was adopted and the
location of the feed point was varied within the radiating patch to arrive at the point of
minimum return loss. This work is also focused on characterization of fabricated antenna in
view of parameters like VSWR, Antenna efficiency, Axial ratio, Gain and radiation pattern.

ABSTRACT
In this paper, a design of pattern reconfigurable microstrip patch antenna and its simulation
using CST- MW simulator is presented. The designed antenna is also fabricated and tested.
The design consists of microstrip patch printed on FR-4 substrate with a coaxial line feeding
on the back of the antenna which is the active element. Two on-chip parasitic elements
(OCPE) also are printed on FR-4 substrate, each of which connected through a via hole to the
ground. The proposed design has the advantage of movable parasitic chip elements with the
same motherboard to control the reconfigurable pattern direction as well as operating
frequency. It is also have the advantages of parasitic elements rotation to fit
reception/transmission required steering angle. The results obtained show that the steering
angle of the main beam in the H-plane depends upon the dimension of the parasitic element
substrate as well as the type of the patch antenna. The presented antenna is suitable for
different application, including Wifi and WiMax systems.

ABSTRACT
Radio wave signals do not travel in a straight line path. There may be some obstacles between
the source and the destination which cause diffraction, reflection, scattering and attenuation.
There are some types of obstacles such as knife edge, wedges and round edges. This paper
shows the diffraction loss caused by wedges based on Uniformal Theory of Diffraction
(UTD) given in (ITU-R Recommendation P.526-12) using Matlab software. It could be said
that this is an important method because radio waves travel over wedge shaped roofs of
buildings and corners of the buildings. In addition this diffraction loss changes for both roofs
and corners for a particular obstruction material. Furthermore, the electrical properties of the
wedge shaped obstacles are affecting the diffraction loss such as conductivity and dielectric
constant. The result shows that higher conductivity leads to have a higher amplitude
oscillation at the receiver.
