✦ Synopsis

Abstract

Folded‐loop antennas for mobile handsets are analyzed, taking into account the influence of the human body. Folding the loop antennas toward the back of a metallic box is found to reduce the peak SAR averaged over 1 g and 10 g of tissues by 30% to 60%, while the radiation characteristics are comparable with those of a monopole antenna. © 2003 Wiley Periodicals, Inc.
