High aperture efficiency wide corrugations bull’s-eye antenna working at 60 GHz

A full metallic Bull’s-Eye (BE) antenna operating at 60 GHz is numerically and experimentally analyzed. The antenna presents wide grooves, rather than narrow ones, which support higher order resonances that lead to a large gain enhancement with just a pair of corrugations, achieving an overall minia...
