A coplanar waveguide feeding SRR antenna including human body effect

Abstract

In this paper a single layer Split Ring Resonant (SRR) antenna with a lumped capacitor based on CPW (coplanar waveguide) excitation is studied to offer a low profile and compact ground plane structure. The effects of basic structural parameters are investigated to give a practical insight. A double layer SRR is examined for comparison. The human body effects are considered as its potential application is in body worn devices. The antenna efficiency (in free space and on a human phantom) is validated in a reverberation chamber.
