## Abstract The resonant loop antenna is examined in terms of its near‐field behaviour. It is shown that the near‐field wave‐impedance varies considerably across the loop diameter. This has a significant effect on the matching to the human body and specific absorption rate. An uneven SAR distributi

Abstract
The circuit model and the near‐field behavior of a novel wide‐band E‐shaped microstrip patch antenna suitable for wireless communication devices are presented. A suitable locally conformal FDTD numerical procedure is employed to analyze the electromagnetic field excited by the radiator, and to derive a frequency‐independent antenna equivalent circuit. Numerical results concerning the antenna parameters are in good agreement with experimental measurements. © 2006 Wiley Periodicals, Inc.
