Abstract

An antenna assembly includes at least two active or main radiating omni-directional antenna elements (100-1, 100-2) arranged with at least one beam control or passive antenna element (115) used as a reflector (305). The beam control antenna element(s) (115) may have multiple reactance elements (150-1, 150-2) that can electrically terminate it to adjust the input or output beam pattern(s) (180, 190) produced by the combination of the active antenna elements (100-1, 100-2) and the beam control antenna element(s) (115). More specifically, the beam control antenna element(s) (115) may be coupled to different terminating reactances (150-1, 150-2) to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use.
