A V-band wideband printed quasi-parabolic sector-reflector antenna with endfire radiation

Abstract

A printed quasi-parabolic sector-reflector antenna with endfire radiation, designed for V-band wireless systems, is proposed. The antenna is made of a low-loss dielectric slab covered by top/bottom metallic covers with interconnecting vias forming the back-reflector for the feeding-probe inside the antenna. The antenna is fed using an integrated feeding line, a coplanar-waveguide-fed probe, on top metallic layer of the antenna without requiring any additional structural layer. The antenna has a maximum radiation gain of 12 dBi and shows the gain of more than 10 dBi in 12 GHz frequency-range within the V-band. The antenna has a very wide gain and impedance bandwidth covering almost the entire FCC-60 GHz wireless band (i.e. from 57 to 64 GHz).
