In this paper, a balanced antenna for mobile handset applications with enhanced
bandwidth performance, that covers four bands (GSM1800, GSM1900, UMTS and 2.4-GHz
WLAN), is investigated. The antenna is a slot planar dipole with folded structure and a dual-arm on each monopole. A wide bandwidth planar balun is employed to feed the wideband balanced antenna from an unbalanced source. A prototype of the proposed antenna is fabricated and
tested. The performance of the antenna is veri¯ed and characterized in terms of return loss, radiation patterns and power gain. The calculated and measured results show good agreement and also con¯rm good wideband characteristics for the proposed antenna with multiband operation.
