Enhancing Beam Steering Performance Using Phased Array Technology for FWA Application

This paper presents a compact beam steerable fully dielectric reflector antenna for FWA application. It consists of a fully dielectric reflector illuminated by a probe-fed 2X2 circular patch antenna array. A peak realized gain of 28.6 dBi and 50.41% aperture efficiency are achieved at 27 GHz. To achieve beam steering the array is moved along the azimuth plane and a scan range of ±23° is obtained with a −1.2 dB scan loss.
