Over the past one decade, there is a rapid growth in development of wireless communication applications. The performance of all such wireless systems depends on the design of the antenna. Microstrip antennas are preferred for majority of their applications and advantages. This paper presents the design and simulation of circular rectangular patch microstrip antenna. The overall antenna is designed and simulated in Ansoft High Frequency Structure Simulator (HFSS) Software. The substrate used in this configuration is Rogers RT/Duroid and substrate is used with  = 2.33. The proposed antenna is used for various wireless communication applications. Gain, Return loss and bandwidth are the performance parameter of the proposed antenna. The proposed antenna is analyzed at resonant frequency of 16.6 GHz & 18.3 GHz. The result calculated is return loss of patch is -35.7673 dB & -29.2070 dB and gain of patch is 5.6925 dB & 12.44 dB respectively.
