Abstract

In this paper, a planar coupled-fed monopole antenna with eight-band LTE/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)x15(W) mm². This antenna, which is printed on a 0.4 mm FR4 substrate and fed by a 50-Ω coaxial cable, can provide two wide operating bandwidths covering 697-1012 MHz and 1598-2795 MHz 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.
