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 rectangular microstrip patch array antenna using HFSS software “Ansoft-High Frequency Structure Simulator” and compare the performance of 2 elements, 4 elements, 8 elements, and 16 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 in terms of return loss, gain, directivity and radiation pattern. Details of simulated results are presented and discussed. Enhancement in gain, directivity and better return loss performance can be obtained by the use of RT-DURROID substrate because Low dielectric constant substrates are generally preferred for maximum radiation. Quarter wave transformer and power divider are used to feed the elements. These arrays are designed to operate at a frequency of 10 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.
