Introduction

I. INTRODUCTION

Microstrip antenna is one of the most popular types of printed antenna. It plays a very significant role in today’s world of modern communication systems. Microstrip antennas are very simple in construction using a conventional fabrication technique[1-2]. The MSAs are used in modern communication applications because of their inherent properties like light weight, planar configuration, ease of compatibility to MMICs, ruggedness etc. In this paper the various microstrip patches are introduced in one platform which can help the researcher to use them for desired applications[3-4].

II. BASIC STRUCTURE OF THE MSA

Microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate  that has a conducting ground plane  on the opposite  side as shown in Fig. 1

The Fig. 3 shows the typical radiation pattern of RMSA in its operating band. It exhibits the broadside and linearly polarized radiation pattern. The gain of 4dB to 6dB can be easily achieved. The gain can be enhanced using various techniques like stacking and use of arrays.

The MSAs are simulated using simulation software’s mentioned below.

1. Ansoft High Frequency Structure Simulator(HFSS)
2. Zeland IE3D
3. CST Microwave Studio
4. Feko
5. Antenna Magus

These softwares are based on different analysis methods. The results obtained by these softwares ensure very close relation with experimental results.

From this over all study it can be concluded that, the microstrip patch antenna finds several applications in modern communication system like global positioning satellite (GPS), Radio frequency identification (RFID) devices, mobile communication and healthcare modules.  The IEEE 802.16 standard Wi Max (worldwide interoperability for microwave access) and WLAN use these antennas for tuning the bands. The advent of its light weight is used in some communication-based applications such as radio altimeters and ATC, command and control systems, remote sensing and environmental instrumentation,. These antennas play a vital role as secondary antennas as a feed element in complex antennas. Due to its compactness the MSAs are used in satellite navigation receivers, mobile radio, biomedical radiators and intruder alarms. The exhibition of broadside radiation pattern by these antenna help in Doppler and SAR/CW radar communication units[6-8]. The MSAs have proved as a low cost tool in establishing better in modern communication systems.
