Abstract

A simple printed monopole slot antenna for penta-band WWAN operation (824~960/ 1710~2170 MHz) in the mobile handset is presented. The monopole slot has a length of 50 mm only and is embedded close to the bottom edge of the system ground plane of the handset with a small distance of 11 mm. By adding a small-size C-shaped strip connected orthogonal to the bottom edge of the system ground plane, good excitation of the monopole slot antenna at its fundamental (0.25-wavelength) and higher-order resonant modes can be obtained. The excited resonant modes form two wide operating bands to respectively cover the GSM850/900 operation (824~960 MHz) and GSM1800/1900/UMTS operation (1710~2170 MHz). Operating principle and radiation characteristics including the SAR (specific absorption rate) results of the proposed monopole slot antenna are described. Measured results of the fabricated antenna are also presented.
