In this paper, the authors present a planar handset antenna having a small size 47Ã?15Ã?0.8mm3 and providing four wide operating bands of at least 698-960, 1710-2690, 3100-3900 and 5150-5850 MHz for the 11-band LTE700/GSM850/900, GSM1800/1900/UMTS/LTE2300/LTE2500, WiMAX 3.5GHz/5.4GHz and WLAN 5.8GHz. The multi-broadband antenna consists of Br-1, Br-2, Br-3 and C-strip and ground plane. The structure is analyzed by S11 and surface current distribution. The simulated and measured results agree well. The gain of the proposed antenna is 1.51-4.12dBi and the radiation efficiency is about 75%-94%.
