On-Body Propagation Performance With Textile Antennas at 867 MHz

In this paper, the on-body propagation performance measured totally wirelessly with 4-mm-thick and 50<formula formulatype="inline"><tex Notation="TeX">$\,\times\,$</tex> </formula>50 mm size textile monopole antennas is presented. At a relatively low operating frequency 867 MHz, with small size, low gain textile antennas mean channel gain values from <formula formulatype="inline"><tex Notation="TeX">$-$</tex> </formula>47 to <formula formulatype="inline"><tex Notation="TeX">$-$</tex> </formula>56 dB including the antenna performances were recorded in various on-body propagation scenarios. The majority of the recorded links could be well described with the Nakagami distribution.
