An all-metal shell mobile smart terminal antenna

Abstract

The invention provides an antenna for a mobile intelligent terminal with a full metal casing, which belongs to the technical field of antennas. The invention includes: a system circuit board, a metal casing, antenna branches and feeding points, a clearance area is provided on the front and back of the system circuit board, the metal casing includes a back cover and a peripheral metal frame connected thereto, and a metal short near the clearance area There are narrow slits on the frame to separate the metal shell to form two independent parts, and an antenna branch is set in the clearance area, one of the antennas is used as a driving unit and coupled with the second antenna branch, the metal shell between the narrow slits, and the antenna branch three to form a loop antenna The parasitic units together cover the low frequency band (824MHz~960MHz) and the high frequency band (1710MHz~2690MHz). The invention increases the frequency band coverage of the antenna, basically realizes the full metal coverage of the equipment while ensuring high performance, and improves the user's requirements for the metal texture and aesthetic feeling of the fuselage.

Description

technical field

[0001] The invention belongs to the technical field of antennas, in particular to an antenna for a mobile smart terminal with a full metal shell. Background technique

[0002] As consumers demand for the appearance and texture of terminal equipment, mobile terminal equipment tends to be designed with a metal body, and mobile terminal equipment with an all-metal body has become a fashion. The metal shell can enhance the structural strength of the mobile terminal device to a large extent and can meet consumers' needs for aesthetics and touch. Therefore, the market competitiveness of mobile terminal devices with an all-metal body is impressive. However, the metal casing often seriously affects the radiation performance of the terminal antenna, and the reason why the radiation performance of the terminal antenna is interfered by the metal casing is mainly that the metal casing surrounds the terminal antenna and forms an energy reflection relative to the terminal ...
