Patent attributes
A high-isolation multiple in, multiple out (MIMO) antenna array includes, in one configuration, a ground plane, and a plurality of antenna transmitting/receiving elements arranged near the periphery of the ground plane, wherein each of the antenna transmitting/receiving elements is resonant at a frequency f. Also, the array includes an isolation antenna element located on the ground plane, between the plurality of antenna transmitting/receiving elements. The isolation antenna element is also resonant at the same frequency f. The plurality of antenna transmitting/receiving elements and the resonant isolation antenna element are arranged on the ground plane arranged so as to achieve substantially greater than 15 dB isolation of the antenna transmitting/receiving elements. In some configurations, at least about 30 dB of isolation of the antenna transmitting/receiving elements can be achieved.
