Problems solved by technology

While all-metal mobile phones improve the quality and grade of mobile phones, the performance of the antenna is also reduced due to the natural signal shielding characteristics of metal. challenge
[0003] The existing antenna design of mobile terminals does not take into account the impact of holding the terminal on the antenna. The performance of the antenna will be different if the user holds the terminal with the right hand and the terminal with the left hand. If this effect is not considered, it will be Directly lead to the degradation of antenna performance and poor user experience

Abstract

The invention discloses a terminal antenna structure. The terminal antenna structure comprises a metal back cover and a metal middle frame, wherein the metal middle frame is arranged on the periphery of the metal back cover; the metal back cover and the top or the bottom of the metal middle frame are isolated by a gap, so that the top or the bottom of the metal middle frame is used as an antenna radiation body, wherein the antenna radiation body is connected with a grounding point in a first position, can be connected with a feed point in a second position through an adjustable capacitor and can be connected with a tuning circuit in a third position through a multi-circuit tuning switch, wherein the antenna radiation body has two working modes; when the terminal is in a left-hand-held state, the antenna radiation body works in a first working mode; and when the terminal is in a right-hand-held state, the antenna radiation body works in a second working mode.

Description

technical field [0001] The present invention relates to antenna technology, in particular to a terminal antenna structure. Background technique [0002] With the fourth generation (4G, 4 th Generation) communication technology is developing rapidly, and current mobile terminals are increasingly supporting 4G networks, such as Long Term Evolution (LTE, Long Term Evolution) networks, which require antennas to have wider bandwidths to meet user needs. On the other hand, with the further popularization of 4G terminals, the homogenization of mobile phones is becoming more and more serious, and people have higher and higher requirements for mobile phones, such as: the texture of the body, the user's online experience, etc. For this reason, many mobile phone manufacturers have launched metal models. Among them, all-metal integrated mobile phones are popular among consumers because of their beautiful appearance, high structural strength, and superior thermal conductivity. While a...
