Abstract
AbstractIn this article, a chiral metamaterial (CMM) with high reflectance is constructed by using both the S‐shaped strip and the grid strip. Numerical simulation results reveal that the reflectance reaches 0.7 and the transmitted wave is converted from y‐polarization to left‐hand circular polarization. Therefore, the proposed CMM has the function of polarized transformation from linear polarization (LP) wave to circular polarization (CP). In addition, a Fabry‐Perot resonator cavity‐like behavior is found in the CMM itself. We design and measure a CP CMM‐based Fabry‐Pérot resonator cavity antenna. A bandwidth of 13.25% (|S11| < −10 dB, AR < 3 dB, and peak gain drop<3 dB) and a peak gain of 14.76 dBic are attained. The proposed antenna has potential applications in advanced nanosatellite communication systems.
