antennas are accepted as more complex to optimise than their
free space counterparts. Use of the body as a platform for
wearable electronics is a topical subject. Omnidirectional
antennas are thought to be useful for antennas in body area
networks. However, the desirable properties of omnidirectional
radiation patterns close to humans are severely diminished due
to the lossy load nature of biological matter and high levels of
scattering due to shadowing and mismatch. To alleviate these
problems two or more antennas can be used on the body. In this
paper, two on body antennas are used with three different
combination techniques in order to evaluate the diversity
performance and then compared with their free space
equivalents. Three diversity techniques are used – Selective,
Maximal Ratio and Equal Gain.
The frequency of operation was 2.4GHz.
