Summary:The purpose of this study is to determine the practical on-body performance of two larger sized dual-band textile antennas using human subjects to see if this relation holds. The results show that a higher conductivity-based textile material in conjunction with a suitably large-sized ground plane performs more resiliently when placed on-body; about a 20% degradation in radiation efficiency is observed as compared with free-space levels, which is much less than the lower conductivity textile material in this study. The authors concur, therefore, that in addition to the conductivity of the textile material, the ground plane dimension is also of crucial importance in relation to how efficient the textile antenna performs on human subjects. The on-body frequency de-tuning of these antennas is also investigated, concluding that in the higher-frequency sub-band, both antennas remain well matched. Theoretical, simulated and experimental evidence is provided to verify the conclusions.
