In this paper, a dual-band cross-polarization converter is proposed. The proposed device can convert linearly polarized incident waves to their cross-polarized transmitted waves. Inspired by the aperture coupled transmitarray, a transmissive multi-layered unit cell structure was designed, which can operate in two frequency bands. The designed structure can manipulate the polarization of the transmitted wave into the cross-polarization of the incident waves at 10.36 GHz and 11.62 GHz. The cross-polarized transmittance of the proposed cross-polarization converter is higher than 0.93. In addition, the transmitted wave has an extremely low co-polarized component, which results in a nearly 100% polarization conversion ratio. The two working frequencies can be tuned independently. The proposed cross-polarization converter was simulated, fabricated and measured. The simulation results confirm with the measurement results.
本文提出了一种双频交叉极化转换器。所提出的器件能够将线偏振入射波转换为其交叉极化透射波。受孔径耦合透射阵列的启发，设计了一种透射式多层单元结构，其可在两个频段工作。所设计的结构能够在10.36GHz和11.62GHz将透射波的极化操纵为入射波的交叉极化。所提出的交叉极化转换器的交叉极化透射率高于0.93。此外，透射波具有极低的共极化分量，这导致极化转换率接近100%。两个工作频率可独立调谐。对所提出的交叉极化转换器进行了仿真、制作和测量。仿真结果与测量结果相符。
