Corrugated plate, subwavelength aperture, very low-profile feeder, wireless local area networks (WLANs)
A very low-profile planar rectangular horn antenna made of a subwavelength aperture surrounded by two grooves on the conducting plate is presented. This structure exhibits good return losses and radiated beam. Its operation is based upon enhanced transmission and beaming through apertures in metallic corrugated plates. Here, the corrugated structure is designed to operate in microwaves and, moreover, a waveguide flange, which has been properly mechanized in the rear part of the structure, is employed for excitation. A new very low-profile planar feeder with reduced size is introduced that could be properly scaled for potential wireless applications.
