本章讨论的是波纹板天线。波纹板天线，在这里介绍，包括一个谐振槽内形成的金属板。谐振槽由矩形腔和波纹包围。由周期性波纹包围的亚波长槽已经被广泛研究以在光学和微波波段提供增强的传输。受光频现象的启发，Beruete等人首先实现并提出了高方向性的单波段和双波段波纹板天线。这是通过将光学结构缩放到微波频率范围内的频率来实现的。一般来说，天线由金属板内形成的谐振槽包围的波纹组成.使用标准的矩形波导对缝隙馈电。波纹可以是直的或圆形的。
This chapter is concerned with corrugated plate antennas. The corrugated plate antennas, presented here, consist of a resonant slot formed within a metallic plate. The resonant slot is surrounded by a rectangular cavity and corrugations. Subwavelength slots surrounded by periodic corrugations have been widely investigated to deliver enhanced transmission at both optical and microwave bands. Inspired by the phenomenon observed at optical frequencies, highly directive single -band and dual -band -corrugated plate antennas were first realized and proposed by Beruete et al. This was achieved by scaling the optical structures to frequencies in the microwave frequency range. Generally speaking, the antennas consist of resonant slot -surrounded corrugations that are formed within a metallic slab. The slot is fed using a standard rectangular waveguide. The corrugations can be either straight or circular in shape.
