An integrated K-port antenna where K is an integer equal to 2 or greater and where the antenna is sufficiently small that it can be enclosed by K&minus;1 overlapping spheres each having a diameter of &lgr;/2 where &lgr; is equal to c/f and f represents an operating frequency of the antenna.

Integrated multiport antenna for achieving high information throughput in wireless communication systems

A wireless communication device comprising a signal processing device coupled to a cluster of multiple port antennas that can simultaneously transmit and/or receive communication signals. The cluster of antennas operates within a frequency band having maximum frequency f, and at least a pair of the antenna ports is placed in a volume of space whose longest linear dimension is &lgr;/3 or less where &lgr; is equal to c/f. During operation of the antenna cluster, the radiation patterns from different antennas have main lobes that point in different directions and have correlations of 0.7 or less with respect to each other.
