Gwo-Yun Lee and Kin-Lu Wong Department of Electrical Engineering National Sun Yat-Sen University Kaohsiung 804, Taiwan Received 22 March 2002 ABSTRACT: By inserting several slits into a rectangular planar monopole, which meanders the monopole, and further bending it into two equal and perpendicular sections, a novel very-low-prole monopole antenna for applications in GSM/DCS dual-band mobile phones is presented. The antenna height is only 7 mm (about 2.1% of the wavelength at 900 MHz) from the ground plane, and the obtained impedance bandwidths cover the required operating bandwidths of the GSM (890
