This paper proposes a microstrip patch antenna (MSPA) in the Ku band for satellite applications. The antenna is small in size with dimensions of about 40 mm×48 mm×1.59 mm and is fed with a coaxial cable of 50 Ω impedance. The proposed antenna has a wide bandwidth of 3.03 GHz ranging from 12.8 GHz to 15.8 GHz. To realize the characteristics of wideband the techniques of defective ground structure (DGS) and etching slots on the radiating element are adopted. The antenna is modeled on the FR4 substrate. A basic circular patch is selected for the design of a dual-frequency operation and in the next step DGS is introduced into the basic antenna and enhanced bandwidth is achieved at both the frequencies. To attain wider bandwidth two slots are etched on the radiating element of which one is a square ring slot and the second one is a circular ring slot. The novelty of the proposed antenna is a miniaturized design and unique response within the Ku band region which is applicable for wireless UWB applications with VSWR <2 and an average gain of 3.6 dB.

Size Reduction and Gain Enhancement of a Microstrip Antenna using Partially D...IJECEIAES
Microwave engineers have been known to designedly created defects in the shape of carved out patterns on the ground plane of microstrip circuits and transmission lines for a long time, although their implementations to the antennas are comparatively new. The term Defected Ground Structure (DGS), precisely means a single or finite number of defects. At the beginning, DGS was employed underneath printed feed lines to suppress higher harmonics. Then DGS was directly integrated with antennas to improve the radiation characteristics, gain and to suppress mutual coupling between adjacent elements. Since then, the DGS techniques have been explored extensively and have led to many possible applications in the communication industry. The objective of this paper is to design and investigate microstrip patch antenna that operates at 2.4 GHz for Wireless Local Area Network WLAN IEEE 802.11b/g/n, ,Zigbee, Wireless HART, Bluetooth and several proprietary technologies that operate in the 2.4 GHz band. The design of the proposed antenna involves using partially Defected Ground Structure and circular/cross slots and compare it to the traditional microstrip patch antenna. The results show improvement in both the gain of 3.45 dB and the S11 response of -22.3 dB along with reduction in the overall dimensions of the antenna. As a conclusion, the performance of the antenna has been improved through the incorporation with the DGS and slots structures regarding the S11 response and the gain. The proposed antenna become more compact. Finally, the radiation pattern of proposed antenna has remained directional in spite of adding slots on the ground plane.

Dual band operation has been obtained by modifying the ground plane of the proposed design with spur-slots. It has been fabricated and tested with the overall size of 21x15x1.6 mm3. The measured results indicate that the proposed antenna yields <-10dB impedance bandwidth of 13.13% and 9.86% which meets the requirement of 3.5GHz and 5.5GHz Wireless Local Area Network (WLAN) and World Wide Interoperability Microwave Access (WiMAX) applications. The approximate lumped equivalent circuit extraction for the proposed DGS fed dual band antenna has been discussed in detail. Because of its stable radiation patterns with low cross polarization,miniature size, high average antenna gain of 2.5dBi and good electromagnetic characteristics, the proposed antenna is a promising candidate for dual mode wireless communication devices.
A Miniature BroadBand Microstrip Antenna for LTE, Wi-Fi and WiMAX Applications IJECEIAES
A Compact microstrip antenna with rectangular slotted radiating element has been developed. Four slots have been introduced on the radiating element with the use of a partial ground plane and a wideband response has been obtained. The bandwidth of the proposed antenna is 1.7 GHz with a percentage bandwidth of 71%. A low-cost dielectric (FR4_EPOXY) has been considered in the development of the proposed antenna. The obtained frequency band is from 1.9 GHz to 3.6 GHz. To investigate the robustness of our modelled antenna the simulation process has been carried out using two different solvers (Finite Element Method and Finite Integration Technique). In addition, the designed antenna was realized and these results were compared with those of the simulation. The proposed antenna is suitable for many LTE bands {1, 3, 7… 38, 40} broadly deployed in European, South American, Asian, and African countries, Wi-Fi (2.4 GHz), and WiMAX technology (3.5 GHz).

Abstract:
In recent years, great interest was focused on microstrip antennas for their small volumes, low profiles, excellent
integration, low costs and good performance. With the continuous growth of wireless communication service and the
constant miniaturization of communication equipment, there are higher and higher demands for the volume of antennas,
integration and working band. This paper presents a single layer monopole hexagonal microstrip patch antenna is thoroughly
simulated for wireless communications system application which are suitable for the 13.71GHz operations. These systems
may include direct broadcast satellite (DBS) system, also known as “Direct-To-Home”. DBS systems are commonly referred
to as “mini-dish” systems. DBS uses the upper portion of the Ku band. The initial design and optimization of the patch
antenna is operating in Ku band (12-18GHz).It has been performed in Zeland IE3D software.

1. INTRODUCTION
In recent years, demand for small antennas on wireless communication has increased the interest of research work
on compact microstrip antenna design among microwave and wireless engineers [1-6]. Because of their simplicity and
compatibility with printed-circuit technology microstrip antennas are widely used in the microwave frequency spectrum.
Simply a microstrip antenna is a rectangular or other shape, patch of metal on top of a grounded dielectric substrate.
Microstrip patch antennas are attractive in antenna applications for many reasons. They are easy and cheap to manufacture,
lightweight, and planar to list just a few advantages. Also they can be manufactured either as a stand-alone element or as part
of an array. However, these advantages are offset by low efficiency and limited bandwidth. In recent years much research and
testing has been done to increase both the bandwidth and radiation efficiency of microstrip antennas.
Due to the recent interest in broadband antennas a microstrip patch antenna [7-8] was developed to meet the need for
a cheap, low profile, broadband antenna. This antenna could be used in a wide range of applications such as in the
communications industry for cell phones or satellite communication. Our aim is to reduce the size of the antenna as well as
increase the operating bandwidth. The proposed antenna (substrate with εr = 4.4) has a gain of 3.19 dBi and presents a size
reduction of 56.55% when compared to a conventional microstrip patch (10mm X 6mm). The simulation has been carried out
by IE3D [19] software which uses the MoM method. Due to the small size, low cost and low weight this antenna is a good
entrant for the application of X-Band microwave communication and Ku-Band RADAR communication & satellite
communication. The X band and Ku-Band defined by an IEEE standard for radio waves and radar engineering with
frequencies that ranges from 8.0 to 12.0 GHz and 12.0 to 18.0 GHz respectively[10]. The X band is used for short range
tracking, missile guidance, marine, radar and air bone intercept. Especially it is used for radar communication ranges roughly
from 8.29 GHz to 11.4 GHz. The Ku band [11-18] is used for high resolution mapping and satellite altimetry. Especially, Ku
Band is used for tracking the satellite within the ranges roughly from 12.87 GHz to 14.43 GHz. In this paper the microstrip
patch antenna is designed for use in a satellite TV at 13.7173 GHz. The results obtained provide a workable an tenna design
for incorporation in a satellite TV. We consider the satellite TV has two different bands one is FSS-band and another is DBS-
band. The DBS systems can also run on C-band satellites and have been used by some networks in the past to get around
legislation by some countries against reception of Ku-band transmissions.
2. ANTENNA DESIGN
The configuration of the conventional printed antenna is shown in Figure 1 with L=6 mm, W=10 mm, substrate
(PTFE) thickness h = 1.6 mm, dielectric constant εr = 4.4. Coaxial probe-feed (radius=0.5mm) is located at W/2 and L/3.
Assuming practical patch width W= 10 mm for efficient radiation and using the equation [6],

coaxial probe-feed (radius=0.5 mm) are shown in the figure 2.
3. RESULTS AND DISCUSSION
Simulated (using IE3D [19]) results of return loss in conventional and simulated antenna structures are shown in
Figure 3-4. A significant improvement of frequency reduction is achieved in simulated antenna with respect to the
conventional antenna structure.
Figure 3: Return Loss vs. Frequency (Conventional Antenna) Figure 4: Return Loss vs. Frequency (Slotted Antenna)
In the conventional antenna return loss of about -7.01 dB is obtained at 13.39 GHz. Comparing fig.3 and fig.4 it may be
observed that for the conventional antenna (fig.3), there is practically no resonant frequency at around 9.12 GHz with a return
loss of around -6 dB. For the simulated antenna there is a resonant frequency at around 9.12 GHz where the return loss is as
high as -23.43 dB.
Due to the presence of slots in simulated antenna resonant frequency operation is obtained with large values of frequency
ratio. The first and second resonant frequency is obtained at f1= 9.12 GHz with return loss of about -23.43 dB and at f2 =

4. CONCLUSION
This paper focused on the simulated design on differentially-driven microstrip antennas. Simulation studies of a
single layer monopole hexagonal microstrip patch antenna have been carried out us ing Method of Moment based software
IE3D. Introducing slots at the edge of the patch size reduction of about 56.55% has been achieved. The 3dB beam-width of
the radiation patterns are 162.914° (for f1), 64.47° (for f2) which is sufficiently broad beam for the applications for which it is
intended. The resonant frequency of slotted antenna, presented in the paper, designed for a particular location of feed point
(4mm, 2.5mm) considering the centre as the origin. Alteration of the location of the feed point results in narrower 10dB
bandwidth and less sharp resonances.
