Abstract:In this work, a wideband compact circularly polarized (CP) antenna using a novel polarization‐rotated metasurface (MS) structure is presented. First, the polarization‐rotated MS structure is designed by using a complementary L‐shaped MS unit cell. By optimizing the width of diagonal gap and radius of corners, the amplitude and phase of its surface impedances along ±45° can be adjusted respectively, and then a large polarization‐rotated bandwidth of 44.4% can be obtained. Secondly, the modal behaviors of the pr… Show more
