Abstract
In this paper, a planar coupled-fed monopole antenna with eight-bandLTE/WWAN(LTE700/2300/2500/GSM850/900/1800/1900 /UMTS) operation for mobile handset device application is proposed. It simply consists of a T-shaped driven strip and a coupled radiating structure, which occupy a small PCB area of 50(L)£15(W)mm 2 . This antenna, which is printed on a 0.4mm FR4 substrate and fed by a 50- › coaxial cable, can provide two wide operating bandwidths covering 697{1012MHz and 1598{2795MHz for LTE/WWAN communication systems. A prototype of the proposed antenna is fabricated, tested and analyzed. From the measurement results, nearly omnidirectional coverage and stable gain variation across the desired LTE/WWAN bands can be obtained with the antenna.
