Abstract

The invention discloses an antenna device and an electronic device. The electronic device comprises a metal cell cover with a slit structure, and a plastic support structure arranged in the slit structure. The antenna device comprises a slit antenna body formed by being along a first edge, in contact with the top end face of the plastic support structure, of the metal cell cover. A connection part is arranged on the metal cell cover to divide the slit antenna body into two segments. The slit antenna body is short circuited with a grounding end through the connection part. The antenna device also comprises a first tuning part, a second tuning part and a feed part which are successively arranged between the connection part and the first end of the slit antenna body. The first tuning part is connected with the grounding end through a first switch matching circuit. The second tuning part is connected with the grounding end through a second switch matching circuit. The feed part is connected with a radio frequency front end through a spring sheet or a flexible circuit board. According to the invention, when multi-band reuse is achieved, radio frequency performance of each brand and light and thin performance of the electronic device can be ensured.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna device and electronic equipment. Background technique [0002] With the rapid development of mobile terminals, mobile terminals with metal texture will continue to be popular in the future. Faced with various metal structures, the antenna signal of electronic equipment has become a challenge for the industry. In addition, in order to meet users' requirements for thinner and lighter appearance of electronic equipment, the layout space of other electronic components of the electronic equipment is very limited, causing the layout of conductive components to affect the performance of the antenna. Contents of the invention [0003] Embodiments of the present invention provide an antenna device and electronic equipment, so as to solve the problems in the prior art of electronic equipment that the antenna interacts with other electronic components and the performanc...
