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] In order not to affect the performance of the antenna, the performance of the antenna can be achieved by slotting the metal back shell, but too many slots affect the appearance. At present, the three-section all-metal back shell has become a trend in smart phone design, and the ratio of the upper and lower metal sections is larger. It has become the focus of competition among various mobile phone manufacturers, but judging from the current popular mobile phone styles on the market, the upper and lower metal parts are still too wide, usually between 5mm and 15mm, resulting in obvious non-conductive plastic areas at the broken seams. Seriously affects the appearance of the phone

Abstract

The invention discloses a metal back-shell based terminal antenna and the terminal. The antenna comprises a metal back-shell, one end of which is provided with a silt. The silt divides the metal back-shell into a bottom part metal frame and a back part metal plate wherein the bottom part metal frame serves as an antenna radiation unit and the back part metal plate serves as a ground. The antenna also comprises a grounding unit, a feed coupling plate and feeding points wherein the ground unit is in connection to the back part metal plate and the feed coupling network feeds in the antenna radiation unit through the feeding points.

Description

technical field [0001] The present invention relates to antenna technology, in particular to a terminal antenna and a terminal based on a metal back shell. 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 which all-metal integrated mobile phones are popular among consumers because of their beauty and fashion. While all-metal mobile phones improve...
