Design of controlled RF switch for beam steering antenna array

By M.M. Abusitta, Dawei Zhou, Raed A. Abd-Alhameed and Peter S. Excell

Abstract

YesA printed dipole antenna integrated with a duplex RF switch used for mobile base\ud station antenna beam steering is presented. A coplanar waveguide to coplanar strip transition was adopted to feed the printed dipole. A novel RF switch circuit, used to control the RF signal fed to the dipole antenna and placed directly before the dipole, was proposed. Simulated and\ud measured data for the CWP-to-CPS balun as well as the measured performance of the RF switch are shown. It has demonstrated the switch capability to control the beam in the design of beam steering antenna array for mobile base station applications
