In this paper, the design of single microstrip patch antenna at 2.5 GHz, simulated with different kind of substrate materials using HFSS will be discussed. Subsequent to the selection of the most desirable substrate based on simulated results, a design of 8 element microstrip patch antenna array at X-band (10 GHz) design and a comparison of simulated and experimental results will be discussed. Typically low-cost, low-weight microstrip base station antenna array with narrow beam forming capability are taken into account. In the small countries, where the small area is required to cover by the emission of microwave beams through satellite only the tight spotted areas have been covered. This patch antenna with narrow beam-width of approximately 20° to 35° are required to complete the satellite communication coverage. Our goal will be to design such an antenna having beamwidth of round about 20° to 30° in azimuth. Using three types of substrate materials FR4, GML1000 and RT/Duroid 5880, the single patch simulated and experimental results are compared in conclusion.
