Abstract
The paper deals with a method for designing a patch antenna with circular polarization to be resonant at 9.5GHz (X-band) for RADAR applications. It aims at overcoming the drawbacks of a single patch antenna. The existing single patch antenna resulted in a gain of 6dB. To improve the gain further, the proposed model consists of a synchronous array of 4 linear elements designed to produce circular polarization at the desired frequency. The simulation of the array antenna resulted in a gain of 8dB with an axial ratio of 2.9dB. The return loss of the patch antenna was found to be −20dB at 9.5GHz.
