Radiation Characteristics Enhancement of Microstrip Triangular Patch Antenna using Several Array Structures

Abstract

In the recent years the development in communication systems requires the development of low cost, minimal weight and low profile antenna that is capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort into the design of a microstrip patch antenna. The aim of this paper is to design and simulate a triangular microstrip patch array antenna using HFSS software and compare the performance of 2 elements, 4 elements and 8 elements patch arrays with that of a single patch for the same operating frequency. Also comparisons are made between the performance of series, corporate and series-corporate feed network. These arrays are designed to operate at a frequency of 11 GHz. Our goal is to obtain a high directivity with better gain and reduced losses, to be especially used for X band applications such as satellite communication, radar, medical applications, and other wireless systems.
