Abstract
Generalized non-limiting embodiments include employing a dipole antenna and/or a half slot antenna. Each of the antennas constitutes three mutually perpendicular radiating elements to achieve good isolation and low antenna signal correlation between the three ports. In one generalized non-limiting embodiment the antennas are fabricated on FR-4 epoxy boards. Experimental results show that the antennas resonate a reasonable frequency and have a desired mutual coupling. In addition experimental results for the diversity performance and the MIMO channel capacity are also provided for these antennas and these results show that the herein described antennas offer good diversity gain and the channel capacity can be increased by as much as three times by using these antennas over conventional antennas.
