Abstract

An active antenna system and algorithm is proposed that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system that will provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by tuning the active antenna. A null-steering technique is implemented to alter the near-field and far-field characteristics to aid in modifying correlation and isolation in the multi-antenna system.

First claim

We claim:

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 stru…
