Efficient printed antenna for body wearable UWB applications

摘要

A wideband antenna suitable for body area networks is presented. The antenna ensemble consists of a wideband dipole, a spacer element and a back patch. The back patch helps direct the energy efficiently into the forward hemisphere. The low profile antenna displays a VSWR <; 2:1 over 3-10 GHz. The front-to-back ratio is greater than 3 dB over this frequency range. Both theoretical and experimental investigations of the proposed antenna are presented.
