Abstract :
A dual-wideband fractal monopole antenna for handheld terminals is proposed. A modified half-Sierpinski gasket patch is used to cover GPS, DCS1800, PCS1800, UMTS, IMT-2000, WiBro (Wireless Broadband Internet Service), Bluetooth, S-DMB (Satellite Digital Multimedia Broadcast) and WLAN bands. The proposed antenna exhibits two wideband frequency resonances. The measured -10-dB reflection bandwidths for two resonant frequencies are 55- (1517-2670-MHz) and 12.6- (5135-5828-MHz). The radiation characteristics and gain of the proposed antenna are also presented and discussed.
