The antenna has two ports, no aperture switching components, and offers a more compact solution than an array. It provides a reconfigurable pattern in the band 2.525-2.595 GHz and a fixed omnidirectional pattern from 2.235 to 2.725 GHz. The measured gains for four investigated configurations are between 2.1 and 3.1 dBi with total efficiencies between 80% and 89%. The antenna is intended to operate with software defined radio [digital beamforming or multiple-input-multiple-output (MIMO)], where the potential of pattern generation using the dual-port antenna can be fully exploited. It offers multiuser pattern reconfiguration at low cost within a limited volume.en621journal article
