Abstract:
1. An active MIMO antenna system, comprising: a first active modal antenna capable of selective operation about a plurality of modes, wherein each of said plurality of modes generates a distinct antenna radiation pattern resulting from the first active modal antenna; the first active modal antenna comprising: a radiating structure disposed above a circuit board and forming an antenna volume therebetween; a parasitic element positioned adjacent to the radiating structure; and an active tuning element coupled to the parasitic element; wherein said active element is configured for one or more of: adjusting a reactance of the parasitic element, or shorting the parasitic element to ground; a second antenna; each of the first active modal antenna and the second antenna being individually coupled to a respective transceiver selected from a first transceiver and a second transceiver; and a processor coupled to at least the first active modal antenna and configured to select the mode from the plurality of modes associated with the first modal antenna such that correlation of the two antenna system is altered for optimal performance.
