Design and simulation of microstrip patch antenna array for X-Band applications

This study contains theoretical analysis of a single element microstrip patch antenna model by using high frequency structural simulator (HFSS) simulation software to support X-Band applications. In our simulations, FR4 epoxy was used as dielectric material with relative permittivity of 4.4. Also, in order to enhance the gain and the bandwidth of the proposed antenna, 4×1 array element is applied. The simulation results have shown that array technique intensely improve the performance of the antenna with the Gain 10.88 dB, Return Loss -36.1 dB, Bandwidth 5.03 GHz and minimum VSWR 1.03.
