Problems solved by technology

[0003] Since electromagnetic waves cannot penetrate metal, when designing a mobile phone, it is usually necessary to place the antenna outside or keep the antenna from being surrounded by metal, which limits the aesthetics of the metal cased mobile phone
[0004] In order to solve the above-mentioned problems, the mobile phone of the related art adopts the metal frame antenna method that directly feeds the metal shell to transmit or receive electric signals. Although this design solves the antenna radiation problem in the metal environment, the antenna of this design The bandwidth is small, especially the low frequency bandwidth is narrow, the efficiency is poor, and when the consumer holds the mobile phone, the hand will have a destructive effect on the performance of this metal frame antenna

Abstract

The invention discloses an antenna module and a mobile terminal using the antenna module. The antenna module comprises a radiation main body, a first branch, a second branch, an antenna feed end and a radio frequency feed source, wherein one end of the first branch is electrically connected with the antenna feed end, and the other end of the first branch is electrically with a first feed point on the radiation main body; the first feed point divides the radiation main body into a first radiation part and a second radiation part; and the second branch is electrically connected with a second feed point on the second radiation part. The antenna module further comprises an impedance matching circuit coupled between the radio frequency feed source and the antenna feed end. The antenna module and the mobile terminal using the antenna module expand the low-frequency bandwidth and solve the influence on the antenna module when a user is holding the mobile terminal.

Description

【Technical field】 [0001] The invention relates to an antenna module, in particular to an antenna module applied in a mobile terminal. 【Background technique】 [0002] With the development of mobile communication technology, mobile phones have gradually become an indispensable electronic product in life. Consumers are no longer only satisfied with the application functions of mobile phones, and the new demand for the appearance of mobile phones is also growing. Mobile phones with metal casings have a good texture and are durable, so they are welcomed by many consumers. [0003] Since electromagnetic waves cannot penetrate metal, when designing a mobile phone, it is usually necessary to place the antenna outside or keep the antenna from being surrounded by metal, which limits the aesthetics of the metal cased mobile phone. [0004] In order to solve the above problems, the mobile phone of the related art adopts the metal frame antenna method that directly feeds the metal casin...
