Broadband printed cross-dipole element with four polarization reconfigurations for mobile base station array antenna applications

Abstract

This paper describes a broadband printed cross-dipole element with four polarization reconfigurations (BPCDE-PR). The BPCDE-PR can configure two linear and two circular polarizations in the operating band of 1.7-2.5GHz. To implement the broadband polarization reconfigurations, switched network type broadband phase shifters are proposed and designed. The fabricated BPCDE-PR prototype with switched network including broadband phase shifters shows good electrical performances and the desired polarization reconfigurable functions in the operating band. © 2011 Soon-Young Eom et al.
