摘要

The purpose of this study is to investigate the application of a polarization conversion meatasurface for constructing a low profile, wideband circularly polarized slot antenna, which consists of a new Polarization conversion metasurface (PCM)-based square-corner-cut artificial magnetic conductor cell structure and a feeding slot antenna. PCM possesses two frequency points of polarization rotation (PR), produced by appropriately adjusting width between the two triangular metallic patches. A 39.3% (4.7-7 GHz) of big PR band was realized through the combination of two neighboring PR frequency points. The impedance bandwidth of PCM based patch antenna was measured to be 43.5% (4.5-7 GHz), with 17.2% (5.3-6.3 GHz) of 3 dB axial ratio (AR) bandwidth and 0.045 lambda(0) of profile. It also generated 7.3 dBic of high broadside gain in operational bandwidth.
