Abstract

An antenna is provided. The antenna includes: an antenna ground plane; a radiating unit parallel to the antenna ground plane, the radiating unit including: a common unit; a first branch extended from the common unit along a first direction; a second branch extended from the common unit along a second direction, wherein the first direction and the second direction are inverse; a third branch separated from the first branch and the second branch and extending outwardly from the common unit; a shorting unit located between a plane of radiating unit located and a plane of the antenna ground plane and connected to the common unit and the antenna ground plane; and a feeding unit located between a plane of the radiating unit and a plane of the antenna ground plane, wherein the feeding unit is separated from the shorting unit and connected to the third branch, and the shorting unit and the feeding unit are located on the same side.

Claims
