Linear to Left-Hand and Right-Hand circularly polarized reconfigurable square patch antenna
A square-shaped patch antenna with high-gain performance and polarization reconfigurability is introduced in this study. This antenna offers the unique capability of seamlessly transitioning between linear polarization (LP) and circular polarization (CP), expanding its versatility in various communication applications. The polarization flexibility is achieved through the strategic integration of two RF switches utilizing p-i-n diodes, strategically positioned within the square slot structure. Through meticulous optimization of the switch placement, the antenna is capable of generating both right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) patterns. Fabrication and testing of the prototype validate the efficacy of the design, showcasing excellent agreement between simulated and measured results. Notably, the antenna demonstrates impressive impedance bandwidths of 5.6 %, 5.2 %, and 6.5 % at a nearly common frequency of 2.7 GHz, coupled with respectable gains of 8.12dBi for LP, 11.19dBic for LHCP, and 10.55dBic for RHCP configurations, respectively. The comprehensive design details, along with extensive experimental and simulated findings, are meticulously presented, underscoring the antenna’s remarkable performance and potential for diverse wireless communication scenarios.
