Abstract

A high-gain, wideband Fabry-Perot cavity antenna is proposed to operate over almost the whole V-band frequency. The antenna's superstrate is made of multiple different concentric dielectric materials, where the central and outer regions have the highest and lowest permittivity, respectively. The antenna's cavity is excited through a waveguide-fed slot antenna, positioned at a distance of 3.4 mm from the flat superstrate. The 3-dB gain bandwidth extends from 47.9 GHz to 73.0 GHz, which equals a fractional bandwidth of 41%. The peak gain of the antenna is 17.37 dB which occurs at 63.0 GHz. The antenna is compact with a size of 2.7λ₀ × 2.7λ₀ × 0.19λ₀ , where λ₀ is the free space wavelength at the center frequency of the operating band (62.45 GHz).
