[0003] However, large-area metal parts have a significant impact on antenna performance, especially when a metal ring is used as a mobile phone antenna. Due to the extremely limited internal space of a mobile phone with a metal back shell or metal frame, the coupling between the metal ring antenna and the adjacent metal back shell Obviously, the energy radiated by the metal loop antenna will be bound due to near-field coupling, which will greatly reduce the antenna radiation performance; at the same time, the frequency bands required by some operators have a large frequency interval from other frequency bands, and the bandwidth of ordinary antennas is difficult to meet their requirements. frequency band

The present invention provides a mobile terminal built-in antenna and a mobile terminal. The mobile terminal built-in antenna comprises a metal loop antenna; the metal loop antenna is provided with a feed point for connecting to the rear case of the mobile terminal; the metal loop antenna is further provided with a first grounding point and a second grounding point which are arranged at two sides of the feed point respectively; and the first grounding point and the second grounding point are used for making the mobile terminal built-in antenna receive different frequency bands. According to the mobile terminal built-in antenna and the mobile terminal of the invention, the mobile terminal built-in antenna is based on a coupling feeding principle and can be applied to a metal rear case; and the grounding points of the metal rear case can be switched, and internal wiring is not additionally adopted, and therefore, the bandwidth of the mobile terminal built-in antenna of the invention can be effectively extended, and the structural strength of a whole unit can be enhanced to a certain extent, and production cost can be reduced.
Description
【Technical field】 [0001] The invention relates to a mobile terminal built-in antenna and the mobile terminal, belonging to the technical field of electronic equipment accessories. 【Background technique】 [0002] Based on the needs of contemporary users for the texture experience of mobile phones with all-metal shells, the metallization of smartphones has become a fashion trend. At the same time, with the development trend of ultra-thin mobile phones, some mobile phone products on the market will cover the circuit board and antenna structure with a metal shell. The metal shell has high strength, is not easy to damage, and has a metallic texture. [0003] However, large-area metal parts have a significant impact on antenna performance, especially when a metal ring is used as a mobile phone antenna. Due to the extremely limited internal space of a mobile phone with a metal back shell or metal frame, the coupling between the metal ring antenna and the adjacent metal back shell ...
