摘要

本文演示了一种具有宽带和非对称传输特性的三层线性偏振变换器的设计和实现。采用两层对角分环谐振器(DSRR)夹层导线，得到了一个厚3.2 mm、工作频带独立的透射型偏振变换器。通过旋转上下DSRR位错可以实现非对称传输特性，其物理机制可以用类似fabry - psamrot的干涉效应来解释。实验结果表明，在8-11 GHz和17-21 GHz频段，极化变换器的正向和反向入射频率的极化转换率均在0.8以上。所提出的极化变换器在微波领域具有作为非对称传输天线罩或类二极管器件的巨大潜力。

Design and Implementation of High Efficiency and Broadband Transmission-Type Polarization Converter Based on Diagonal Split-Ring Resonator

In this paper, the design and implementation of a three-layer linear polarization converter having broadband and asymmetric transmission (AT) properties is demonstrated. A 3.2 mm thick transmission-type polarization converter with two separate operating frequency bands is obtained with a cut-wire sandwiched by two layers of diagonal split-ring resonator (DSRR). The asymmetric transmission property can be realized by rotating the upper and lower DSRR dislocation, and its physical mechanism can be explicated by the Fabry-Pérot-like interference effect. Experimental results are presented and compared to numerical simulations, and they demonstrate that the proposed polarization converter has a significantly polarization conversion ratio over 0.8 in frequency bandwidths 8–11 GHz and 17–21 GHz for the forward and backward incidences. The proposed polarization converter has a great potential to be used as an asymmetric transmission radome or diode-like device in microwave domain.
