Abstract—In this paper, an antenna composed of an inverted L-shaped feeding strip and a shorting strip with three branches for LTE/WWAN mobile phones is presented. With the help of novel ground plane slots, the proposed antenna can realize miniaturization (34 × 15 mm2) and multiband to cover LTE/WWAN bands. The measured bandwidth (3 : 1 VSWR) of the proposed antenna is 156 MHz (810–966 MHz) at the low band and 1937 MHz (1548–3485 MHz) at the high band. Moreover, the lowest measured radiation efficiency of the fabricated antenna is more than 54% in the whole operation band. The proposed antenna has been successfully fabricated and measured, and there is a good agreement between simulated and measured results.
