Effect of wearable antenna polarization and directivity on on-body channel path gain at 60 GHz

Measurements of on-body dynamic propagation channels have been performed at 60 GHz using dual-polarized scalar horns. The measured cumulative distribution functions (CDF) were compared to those reported previously with monopole antennas. The performances of horn and monopole antennas were compared in various on-body channels and it was found that omnidirectional low-gain antennas produce stronger path gain in some channels. It was concluded that polarization diversity is unlikely to provide a significant gain but the channel capacity may be improved by using several polarization channels in a multiple-input multiple output (MIMO) system.
