Investigation of performance parameters of different wearable narrowband antennas in close proximity to the human body

This paper investigates and compares the on-body performance parameters of five different narrowband antennas at 2.45 GHz. Parametrical analysis addressing the human body effects on the performance parameters of different types of narrowband antennas have been presented. The study was performed by combination of numerical simulation and experimental investigation. The antennas used in this study are microstrip fed patch, wire monopole, printed monopole, inverted L and circular loop.
