Six-Beam Reconfigurable Wire Antenna
Six-Beam Reconfigurable Wire Antenna Ashraf Abuelhaija1 and Klaus Solbach2 1 Hochfrequenztechnik, Universität Kassel, 2Hochfrequenztechnik, Universität Duisburg-Essen, Germany However, a simpler configuration was found which can be remotely switched in its beam direction in steps of 60° in azimuth. This antenna requires only one support pole and uses inverted-V wire dipoles to create a 2-element
