This paper describes the design of polarization reconfigurable single fed patch antenna with two perturbed rectangular ring slots and two PIN diodes at different positions on the ground plane. The topology of patch antenna is suitable for 9.3 GHz satellite and marine RADAR applications. The sense of polarization is controlled by switching of the PIN diodes can generate two circularly polarized (RHCP & LHCP) as well as linearly polarized waves. In this design, slots are placed in ground plane which avoids additional DC biasing and minimizes effect caused by PIN diode on radiation performance of patch antenna so that the patch is unperturbed, which leads concise structure. The simulated results for placements of slots at different positions on the ground plane results in three polarization states with acceptable return loss. This design achieves good impedance bandwidth, axial ratio, gain and radiation properties. Simulation study has been done by incorporating HFSS V-16.2 platform.
