Abstract

In this paper a complete dispersion analysis and radiation pattern calculation of 1-D periodically corrugated metallic surfaces is presented for the first time. A full-wave periodic method is presented and performed on a setup of corrugated unit cells. Results are compared to an analytical periodic method that consists in the solution of a transverse resonance equation at the level of the gap openings. Both methods are applied on a corrugated antenna design at 15 GHz and results show a leaky wave radiation effect. The broadside radiation frequency range of the symmetrically fed infinite size antenna can be predicted, considering the beam-splitting condition. The radiation patterns of a practical finite antenna are calculated and are in good agreement with full-wave simulations.
