Abstract

In this paper, the design of a tripleband antenna for the space efficient integration into mobile phones is presented. The antenna is matched to operate at GSM900/GSM1800/GSM1900 standards. In order to minimize the SAR value (specific absorption rate), mainly in the GSM900 frequency range, the current distribution on the casing of the mobile is split by additional metal strips. The investigations are based on numerical simulations using the FDTD (finite difference time domain) field solver EMPIRET/spl trade/ by IMST.
