Abstract
In this work, several antenna prototypes based on the Extraordinary Optical Transmission phenomenon are developed. They all share in common the property of being all-metallic, flat and low profile. The radiation of a central slot is boosted by texturing the output metallic plane. Enhancement depends directly on the number of grooves carved. Thus, a rich variety in the farfield response can be obtained changing the number of corrugations. Among the prototypes a dual-operating-band planar horn antenna with low profile is presented. It is also seen that by giving the structure rotational simmetry the gain can be increased, resulting in the high-gain Bull's-Eye antenna. Other approaches related with the perturbation profile are under development. The behavior of the current prototypes is very similar to those reported in optics. In this way, a new concept of a very low profile feeder is proposed with potential wireless applications.
