A UWB cavity-backed compound Power-Archimedean slot spiral for body centric wireless communications applications

In this work, the performance of a cavity-backed compound Power-Archimedean slot spiral antenna is analyzed in free space and in the proximity of human body. Results show that the antenna behavior remains stable throughout the FCC UWB band (3.1-10.6 GHz) when in close proximity to the human body. Thus, this type of antenna is a viable candidate for body centric communications.
