Personal and body area network channels between Dual Band Button Antennas

This paper describes an assessment of space diversity for bodyworn dual band metallic button antennas. The optimal combination of locations has been assessed according to the received signal envelope, cross-correlation coefficient and diversity gain for the ISM bands at 2.45 and 5.5 GHz. Received signal envelopes were combined using the selection, maximum ratio and equal gain combining algorithms. Results are taken with both vertical and horizontal polarizations for different body positions with respect to the transmitting antenna.
