提出并分析了一种基于铁氧体平板中法拉第旋转效应的非互易天线罩。这种天线罩允许在一个方向上传输信号，并在相反方向上衰减信号。它包括两层条形光栅，位于铁氧体板的每一侧，由用于适当反射的高导电条和用于反射/耗散的薄高损耗条组成，以及用于匹配的三个介电层。采用广义散射矩阵（GSM）方法对天线罩进行了严格的分析，并在两个宽带天线之间对其性能进行了实验验证。测量结果表明，在隔离和传输方向的21 dB和0.85 dB的损失，分别。
A non-reciprocal antenna radome based on the Faraday rotation effect in a ferrite slab is proposed and analyzed. This radome allows transmission in one direction and attenuates the signal in the opposite direction. It includes two layers of strip gratings on each side of the ferrite slab, consisting of highly conductive strips for proper reflection, and thin highly lossy strips for reflection/dissipation, and three dielectric layers for matching. The radome is analyzed rigorously by the generalized scattering matrix (GSM) method and its performance experimentally demonstrated between two broadband antennas. The measured results show 21 dB and 0.85 dB loss in the isolation and transmission directions, respectively.
