Millimeter wave corner reflector antenna array

In this paper we introduce new millimeter wave printed arrays with eight axially placed dipoles fed by a symphase network with the corner reflector. Three different typical beamwidths are investigated by a variation of the corner angle. Antennas are simulated and realized in the frequency range about 26 GHz which is popular for microwave communication networks. Three antennas are presented with different H-plane beamwidths (intended for azimuth) of 55/spl deg/, 110/spl deg/, and 180/spl deg/ and gains of 19.3 dBi, 16.5 dBi, and 14 dBi respectively, all having E-plane beamwidth of 7/spl deg/ (intended for elevation). Losses are less than 1 dB.
