[0004] The invention patent application with the application number 201410259438 discloses a smart phone antenna with a metal frame that can cover seven frequency bands. The smart phone antenna divides the metal frame into several parts by setting a power-off gap and a short-circuit connector. Using coupling excitation However, the coupling excitation is quite sensitive to the position and distance of the surrounding metal devices, and there is a risk of instability during the development process, requiring multiple debugging cycles

Abstract

The invention discloses a multiband antenna based on a metal frame, comprising the metal frame, a metal middle plate and an insulation bracket; the metal frame and the metal middle plate are arranged on the insulation bracket; a first slot and a second slot are arranged on the bottom edge of the metal frame; the metal frame is divided into a first-section metal frame, a second-section metal frame and a third-section metal frame by the first slot and the second slot. The antenna provided by the invention is advantaged by that a feed-in unit directly feeds in the first-section metal frame to provide stable antenna performance; the energy is coupled to the second-section metal frame and the third-section metal frame through the first slot and the second slot; the working frequency is controlled through combining a first short circuit connector and a second short circuit connector; the bandwidth of the antenna radiation is increased; therefore the antenna satisfies the multiband design demand of a long term evolution upgrade technique; meanwhile, the beauty and toughness of the metal frame are taken into consideration.

Description

technical field [0001] The invention relates to antennas, in particular to a metal frame-based multi-band antenna. Background technique [0002] In recent years, with the rapid development of mobile communication technology, people not only enjoy various convenient functions brought by mobile terminals, but also pay more and more attention to the exquisite appearance of terminals. The use of light, thin and small metal materials has become an inevitable trend. However, the traditional antenna Designing in the application of this metal appearance will face the problem of performance degradation, which brings severe challenges to antenna design. [0003] The invention patent application with the application number 201510167751 discloses an antenna module and a mobile device based on a metal frame. In addition to the antenna body of the metal frame, its structure also includes two switches, through which the working mode of the antenna can be switched in real time to improve mo...
