Abstract

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.
