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.
