This paper describes about a broadband cross-dipole element with four polarization reconfigurations (BCDE_PR). The BCDE_PR can configure two linear and two circular polarizations in the operating band of 1.7~2.5 GHz. To implement broadband polarization reconfigurations, broadband phase shifters of switched network types were chosen. The fabricated BCDE_PR prototype showed good electrical performances and polarization reconfigurable functions in the operating band.
