Abstract

Cellular telephone handsets are now being designed to have dualmode capabilities. In particular, GSM and DCS1800 modes are used in Europe, and PCS and AMPS modes are used in the USA. A novel planar dualband internal antenna for handsets which operates in the ∼0.9 and 1.8GHz bands is proposed. The dualband antenna has almost the same size as a conventional internal antenna operating in the 0.9GHz band. Good dual-band operation was obtained for frequency ratios in the range 1.3-2.7.
