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 terminal antenna based on a metal rear shell and a terminal. The terminal antenna comprises a metal rear shell, a conducting medium, a grounding element, a feed matching network and a feed point, wherein a gap is formed in one end of the metal rear shell, and the gap is used for partitioning the metal rear shell into a bottom metal frame and a back metal plate, wherein the bottom metal frame serves as an antenna radiating unit, and the back metal plate serves as ground; the conducting medium is arranged on the side edge or top of the metal frame of the metal rear shell; at least one point on the conducting medium is coupled or short-circuited with the bottom metal frame; the grounding element is connected with the back metal plate; and the feed matching network is fed in the antenna radiating unit through the feed point. According to the terminal antenna based on the metal rear shell and the terminal, the gap is extremely close to the bottom end of the metal frame, so that a common three-section type design is extremely approximate to a full-metal integrated design, and the conducting medium is arranged on the side edge or top of the metal frame of the metal rear shell so as to extend a covering frequency band of the antenna, so that the frequency band range of the antenna is larger.

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 rapid development of the fourth generation (4G, 4thGeneration) communication technology, current mobile terminals are increasingly supporting 4G networks, such as Long Term Evolution (LTE, Long Term Evolution) networks, which require antennas with a wider bandwidth to Meet the needs of users. On the other hand, with the further popularization of 4G terminals, the homogeneity of mobile phones has become more and more serious, and people have higher and higher requirements for mobile phones, such as the texture of the body and the user's Internet experience. To this end, many mobile phone manufacturers have introduced metal models, among which all-metal integrated mobile phones are popular with consumers for their beauty and fashion. While the all-metal mobile phone improves the texture a...
