Planar Coupled-Fed Monopole Antenna for Nine-Band LTE/WWAN/GPS Mobile Handset Application

In this paper, a planar coupled-fed monopole antenna with nine-band LTE/WWAN (LTE700/2300/2500/GSM850/900/1800/1900/UMTS) operation for mobile handset device application is proposed. It simply consists of a offset T-shaped driven strip and a capacitive loaded coupled radiating structure, which occup...

Summary:In this paper, a planar coupled-fed monopole antenna with nine-band LTE/WWAN (LTE700/2300/2500/GSM850/900/1800/1900/UMTS) operation for mobile handset device application is proposed. It simply consists of a offset T-shaped driven strip and a capacitive loaded coupled radiating structure, which occupies a small PCB area of 60(W)x15(L) mm 2 . This antenna, which is printed on a 0.8 mm thick FR4 substrate and fed by a 50-O coaxial cable, can provide two wide operating bandwidths covering 672-1228 MHz and 1394-2876 MHz for LTE/WWAN communication systems. Also, a SEMCAD software is applied in evaluating SAR values. 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.
