The Wheeler cap method is used to measure the efficiency of antennas for use in on-body communication systems. A monopole and a planar inverted F antenna on small ground planes were mounted in contact with body phantont material and their efficiency measured using the Wheeler cap and by a conventional anechoic chamber method. Results front the two methods show close agreement and also are close to results of simulations using commercial sofiware. (c) 2006 Wiley Periodicals, Inc.
