Abstract: In the recent years, the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are 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. Rectangular microstrip 6X6 patch array antenna performance dependency on permittivity of substrate material at 2.4GHz is evaluated using twelve different substrates and their output characteristics are simulated using commercial Ansoft HFSS software. Keywords: Rectangular Microstrip patch array, performance evaluation, Substrate materials, HFSS. I. INTRODUCTION Microstrip patch antennas are playing a vital role in the communication systems of present technology. They are having number of applications and advantages like low profile, light weight, ease of fabrication and many more except the drawback of narrow bandwidth. Many forms of patch antennas are available in different packages. Rectangular patch array of 6X6 elements for GPS and WLAN applications is designed and its performance is observed for different substrate materials. The microstrip patch antenna radiates because of the fringing fields between the patch edge and ground plane [1-5]. Thick dielectric substrate with low dielectric constant is preferable for better radiation, bandwidth and efficiency. But the disadvantage is the antenna size increases. To overcome this size problem we have to go for substrates with higher dielectric constant, which
