2 × 1 Circular Array Patch Antennas with Double Circular Slots for WLAN Application

The purpose of this paper is to presents entire design of 2 × 1 circular array patch antenna for WLAN application of 2.4 GHz. Circular array with double circular slots microstrip antenna modeled due to the low profiles and easy to fabricate. The circuit was designed by using CST Microwave Studio for the entire dimension. The simulation results of the antenna are done to observe the return loss, radiation pattern, gain, directivity and bandwidth performance. This proposed circular array patch antenna has radiate −24.707 dB at resonant frequency of 2.40 GHz. The bandwidth of this antenna is 53 MHz while the gain is 8.521 dB. Two parametric studies on the effect of the two different circular radiuses (R 1 and R 2 ) are done in this work.
