Problems solved by technology
However, electromagnetic waves cannot penetrate metal, and the antenna system is completely placed in the metal casing, which cannot meet the antenna performance testing standards. Related technologies adopt the method of setting gaps on the metal back cover to radiate signals, which destroys the integrity of the overall shape

The all-metal back shell antenna system includes a metal back shell, a circuit board with a main ground point, a main antenna module and a small antenna module electrically connected to the circuit board; the metal back shell includes a main body, four side walls and Two slits, the two slits divide the metal back shell into a first metal part, a second metal part and a third metal part which are insulated from each other; the first metal part includes a top slit, and the second The metal part includes at least one bottom slit; the main antenna module includes a matching circuit, a main feed point and at least one grounding point arranged on the circuit board; the small antenna module includes at least one small antenna unit, and the small antenna module The antenna unit includes a feed point and at least one ground point. Compared with related technologies, the all-metal back shell antenna system of the present invention can maintain the integrity of the metal back shell to the greatest extent, and has a beautiful appearance.
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...
