A Wideband Reconfigurable Feeding Network for Quadruple Polarization Antenna

Abstract

A Wideband reconfigurable feeding network for quadruple linear and circular polarization is proposed in this paper. The proposed reconfigurable feeding network is designed with RF switches and wideband coupler. The feeding network provides selective linearly and circularly polarized states. RF switches and double-section branch-line coupler operates in a wideband frequency range. A stacked patch antenna is introduced as a radiator to generate quadruple polarization in a wideband frequency. Peak gain is above 4.8dBi for the respective polarization in the 2.2GHz to 2.6GHz range. The feeding network itself covers over IGHZ (2.OGHz-3.OGHz).
