Abstract
In this paper, we propose a multi-polarized Fabry-Pérot resonator cavity (MPFPRC) by integrating the multilayer partially reflective metasurface (MPRM), the feed of multi-polarized slot coupling patch antenna and the reflective ground in X-Band. The MPRM consists of first-layer square metal patches, second-layer metal ground with square slots, third-layer square metal patches and fourth-layer partially reflective patches. Based on the MPRM, the proposed MPFPRC is capable of transforming 0°, 45° and −45° linearly polarized (LP) waves emitted by the feed into LP beam, left-handed circularly polarized (LHCP) beam and right-handed circularly polarized (RHCP) beam, respectively. Finally, the designed MPFPRC is simulated, processed and measured. The experimental results verify that the −3 dB gain bandwidth of LP is 9.1–10.2 GHz, the −3 dB gain bandwidth and 3 dB axial ratio bandwidth of the LHCP are 9.0–10.0 GHz and 9.2–10.0 GHz, and the −3 dB gain bandwidth and 3 dB axial ratio bandwidth of the RHCP are 9.0–10.0 GHz and 9.3–10.0 GHz.
