Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to solve the above-mentioned technical problems of relatively weak radiation performance and limited bandwidth of the mobile phone antenna in the conventional technology, in one embodiment, a terminal back cover is proposed. The back cover of the terminal is suitable for a terminal with an all-metal shell design, that is, the back cover and the side wrapping of the terminal are made of metal. In this embodiment, the te...

Abstract

The embodiment of the invention discloses a terminal back cover. The terminal back cover comprises a main ground part and a radiation part made of metal material, a gap parallel to a short side of the rectangular mobile back cover and filled by an insulation material is arranged between the main ground part and the radiation part, and the main ground part is connected with a ground wire on a terminal main board; the radiation part is used as a radiating body of an antenna of the terminal, the inner surface of the radiation part is provided with a first feed point to connect with a feed wire on the terminal main board; the edge of the radiation part of the terminal back cover is further provided with a first metal route extending to the internal of the terminal and parallel to the inner surface of the radiation part. An antenna system at the terminal back cover provided by the invention is lower in antenna clearance rate requirement and higher in radiation performance.

Description

technical field [0001] The invention relates to the technical field of mobile phone antennas, in particular to a terminal back cover. Background technique [0002] In traditional technologies, as users' requirements for the appearance and experience of mobile terminals continue to increase, more and more mobile phones use metal casings. However, if the mobile phone antenna is designed according to the built-in antenna in the traditional technology, the mobile phone antenna will be easily shielded by the metal shell due to the closedness of the metal casing. Mobile phone antennas are often mid-frame antennas, loop or slot antennas, usually in the form of metal mid-frame + plastic back cover, filling plastic to breakpoints or gaps, but the above-mentioned metal mid-frame + plastic back cover mobile phone All metal back covers are not supported. [0003] In the traditional technology, in order to use an all-metal back cover and maximize the use of mobile phone components, the...
