Abstract

The application relates to an antenna installed on a mobile terminal. The mobile terminal includes a radiation part and a circuit board. The circuit board includes a side and a ground layer. The radiation part is divided into a feeding branch and a parasitic branch by insulating gaps. The circuit board and the radiation part enclose a gap, the feed branch extends to the gap with a feed branch for feeding the antenna, and the parasitic branch extends to the gap with a ground branch electrically connected to the ground. The antenna induces a current loop around the gap on the ground, feed stub and parasitic stub. The antenna described in this application forms a resonance at the position where the induced current is large, thereby ensuring that the communication signal has greater power, so that even when the mobile terminal is in the head-hand mode, the efficiency attenuation of the antenna can be controlled, and a good call effect can be maintained. .

Description

technical field [0001] The present application relates to the communication field, and in particular to an antenna and a mobile terminal including the antenna. Background technique [0002] Most of the current mobile terminals have a call function, and an antenna for communicating with the outside is provided inside. Most of the mobile terminals are in the head-hand mode when the user is making a call, and the antenna signal attenuation of the mobile terminal in the head-hand mode is relatively serious, which affects the call effect of the mobile terminal. Contents of the invention [0003] The purpose of this application is to provide an antenna that can better maintain the performance of signal transmission and reception in the head-hand mode, including the following technical solutions: [0004] An antenna, comprising a feeding branch, a parasitic branch, a feeding branch, a grounding branch and a grounding part, the antenna device is provided in a mobile terminal, the...
