A broadband folded planar monopole antenna for mobile phones

This article presents a broadband folded planar monopole antenna suitable for DCS (1710–1880 MHz), PCS (1850–1990 MHz), UMTS (1920–2170 MHz), and WLAN (2400–2484 MHz) operations for mobile phones. In addition to the broadband operation, the proposed folded monopole has compact dimensions of 10 mm height, 5 mm width, and 17.5 mm length. Experimental results of the constructed prototype are presented and discussed.
