Microstrip patch antennas are the most useful antennas for the present trend of applications especially in communication. In this paper, the proposed antenna presents the design of novel circular patch microstrip antenna array operating at 24GHz.One way of attaining antenna gain is to use an array of elements. The antenna array consists of 4 identical truncated patches that are fed through the microstrip line. The proposed antenna is a circular patch array of 2x2 elements that are etched on the material of FR-4 epoxy substrate with dielectric constant of 4.4. The operating frequency of an antenna is at 24GHz. The designed antenna has the gain of 10dB and return loss of -17dB.The proposed model is simulated using Ansoft HFSS and its return loss and radiation pattern are analyzed.
