Abstract

The invention provides a full metal back shell antenna system, which comprises a metal back shell, a circuit board with main grounding points, and a main antenna module and a small antenna module electrically connected with the circuit board, wherein the metal back shell comprises a main body part, four side walls and two gaps; the two gaps cut the metal back shell into a first metal part, a second metal part and a third metal part which are insulated and separated mutually; the first metal part comprises a top gap; the second metal part comprises at least one bottom gap; the main antenna module comprises a matching circuit, a main feed point and at least one grounding point arranged on the circuit board; the small antenna module comprises at least one small antenna unit; and each small antenna unit comprises a feed point and at least one grounding point. Compared with the prior art, the full metal back shell antenna system can keep integrity of the metal back shell to the largest degree, and the appearance is attractive.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal antenna system. 【Background technique】 [0002] With the development of mobile communication technology, various electronic products play an important role in people's entertainment and life, and various electronic products are gradually updated to electronic communication products with communication functions, among which the antenna system is one of the core components of electronic communication products one. [0003] The radiation section is an important part of the antenna system. In electronic communication products in the related art, the radiation part of the antenna system is arranged on the surface of the plastic back cover. Since the plastic back cover does not shield the radiation of the antenna system, this implementation is relatively easy. [0004] However, with the changing needs of consumers, the demand for electronic communication produc...
