Title
(EN) Antenna structure and terminal equipment
(ZH) 一种天线结构及终端设备
Abstract
(EN)
The invention provides an antenna structure and terminal equipment. The antenna structure comprises a feed source, a metal arm and an impedance matching network, wherein the metal arm is provided witha gap used for diving the metal arm into a first metal arm and a second metal arm; in addition, one end of the first metal arm and one end, which is far away from the gap, of the second metal arm areindependently subjected to ground connection; a feeding point is arranged on the preset position of the first metal arm; and the impedance matching network is independently connected with the feedingpoint and the feed source. By use of the antenna structure, while antenna performance requirements are met, one antenna structure can be used for covering a plurality of frequency bands, the number of antennae can be reduced so as to be favorable for reducing a structure space occupied by a total feed network and lowering the layout difficulty of a complete machine antenna, and in addition, the number of the gaps of the complete machine antenna can be reduced so as to be favorable for improving strength intensity and meet the appearance requirements of a complete machine product.
