On-body radio channel performance of a small printed quasi-self-complementary ultra wideband antenna

The on-body radio channel performance of a small printed quasi-self-complementary ultra wideband (UWB) antenna is investigated in this paper. Measurement campaigns are performed in the chamber and in an indoor environment. The path loss was modeled as a function of distance for 34 different receiver locations for propagation along the front part of the body. A reduction of 16.34% path loss exponent is noticed in case of indoor environment as compared to anechoic chamber. In addition, the path loss has been characterized for eight different on-body radio channels. The proposed antenna shows very good on-body radio channel performance.
