Abstract

A polarization rotation second order dual-band aperture coupled based frequency selective surface (FSS) is presented in this letter. It produces different polarization rotation angle for both the bands. The corner truncated square patch resonators are used to examine dual-band responses. The patch resonators are placed back-to-back through metallic aperture coupled layer in the middle. Two passband responses are obtained with sub-patch resonator I (SPR I) and sub-patch resonator II (SPR II) patch resonators. In first passband, two orthogonal component provide $18 0^{\circ}$ phase difference. Similarly, in second passband $0^{\circ}$ phase difference is occur. Thus, rotation in polarization is occurs in both passband. The prototype of the proposed FSS is fabricated and simulation results are verified with measured results.

基于频率选择表面的双波段双偏振孔径耦合

提出了一种基于偏振旋转二阶双频孔径耦合的频率选择表面。两个波段的偏振旋转角度不同。角截断方形贴片谐振器用于检测双带响应。贴片谐振器通过中间的金属孔耦合层背对背放置。用子贴片谐振器I （SPR I）和子贴片谐振器II （SPR II）获得了两个通带响应。在第一通带中，两个正交分量提供18个0°$18{0}^{\circ}$相位差。同样，在第二通带0°${0}^{\circ}$也会发生相位差。因此，极化中的旋转发生在两个通带中。制作了FSS的原型，并将仿真结果与实测结果进行了验证。
