An electronically switchable wideband pattern diversity antenna
A wideband pattern diversity antenna operating at 5.5 GHz is proposed. The antenna is a monopole radiating element with two orthogonal feeds. The antenna has a bandwidth of 90% over which the radiation patterns are consistent. A broadband phase shifting network is integrated with the antenna. Single pole double throw (SPDT) switches are used with the phase shifting network to electronically control radiation pattern of the antenna. Consistent diversity performance is achieved in terms of the radiation pattern by the integrated system over the entire bandwidth as that of the antenna.
