Abstract
A multi-mode antenna system include at least a first modal antenna and a second modal antenna. The first modal antenna is disposed on a ground plane of a circuit board and configurable in a plurality of different modes. The first modal antenna can include a driven element, at least one parasitic element and an active element configured to adjust a reactance of the at least one parasitic element. The multi-mode antenna system further includes a second modal antenna disposed on the ground plane and configurable in a plurality of different modes. The second modal antenna can include a driven element, at least one parasitic element, and an active element configured to adjust a reactance of the at least one parasitic element. The parasitic element of the second modal antenna is positioned such that adjusting the reactance of the parasitic element affects the radiation pattern associated with the first modal antenna.
