摘      要：Partially-reflecting surface (PRS) resonant antennas have attracted significant attention for the past two decades. However, their radiation performance is still not as good as expected. This paper proposes a non-resonant PRS antenna that does not require the conventional resonant condition that limits design flexibility and gain performance. It consists of a PRS, a ground, a small feed, and a transparent phase-correcting surface (PCS) placed above the PRS for phase compensation. The ray-tracing method is used to analyze the proposed non-resonant PRS antenna, and numerical simulations are conducted to verify its effectiveness. Three prototypes are fabricated and tested, and the measured results show a better gain performance than the conventional PRS antennas that require the resonant condition. © , CC BY.
