Abstract :
A Fabry-Pérot cavity antenna based on a dual-layer partially reflected surface (PRS) structure is designed, fabricated and measured at 80 GHz (band-E). The PRS is composed of two frequency selective surfaces, each comprising a periodic array of square metallic patches. When excited by a single primary source, the antenna´s gain and directivity increase by ~10 dB from 81 to 86 GHz. The dimensions of the prototype compact antenna are 100 × 100 × 4 mm3.
