Abstract

A novel compact internal triple-band handset antenna for covering the GSM900, DCS1800, and PCS1900 bands is presented. This proposed antenna mainly consists of two folded meandering branches to meet the needs for triple-band operation and occupies a total volume of 32Ã—10Ã—4 mm³. The HFSS simulation software is employed for optimizing the design parameters. A prototype has been fabricated and studied. Both simulated and measured results show that the resulting antenna is able to operate in the GSM, DCS and PCS bands with return loss less than -7.5 dB (VSWR < 2.5). The measured maximum radiation gains at the frequencies of 0.92, 1.8 and 1.9 GHz are about 2.2, 4.6 and 4.8 dBi, respectively.
