Abstract

Abstract In this paper, we propose a multi-polarized Fabry-Pérot resonator cavity (MPFPRC) by integrating 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 -3dB gain bandwidth of LP is 9.1-10.2 GHz, the -3dB gain bandwidth and 3dB axial ratio bandwidth of the LHCP are 9.0-10.0 GHz and 9.2-10.0 GHz, and the -3dB gain bandwidth and 3dB axial ratio bandwidth of the RHCP are 9.0-10.0 GHz and 9.3-10.0 GHz.

x波段多层部分反射超表面的多极化法布里-帕氏谐振腔

本文提出了一种将多层部分反射超表面(MPRM)、多极化槽耦合贴片天线馈源和x波段反射地集成在一起的多极化法布里-帕氏谐振腔(MPFPRC)。MPRM由第一层方形金属贴片、第二层带方槽的金属接地、第三层方形金属贴片和第四层部分反射贴片组成。基于MPRM，所提出的MPFPRC能够将馈源发射的0°、45°和-45°线极化(LP)波分别转化为LP波束、左手圆极化(LHCP)波束和右手圆极化(RHCP)波束。最后，对所设计的MPFPRC进行了仿真、加工和测量。实验结果证实，LP的-3dB增益带宽为9.1 ~ 10.2 GHz, LHCP的-3dB增益带宽和3dB轴比带宽分别为9.0 ~ 10.0 GHz和9.2 ~ 10.0 GHz, RHCP的-3dB增益带宽和3dB轴比带宽分别为9.0 ~ 10.0 GHz和9.3 ~ 10.0 GHz。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
