Problems solved by technology

[0002] With the development of communication technology, electronic equipment has more and more functions, and there are more and more internal devices and communication antennas in electronic equipment. Compression will make the distance between the metal structure inside the electronic device and the antenna smaller. According to Lenz's law, an induced current will be generated on the metal structure close to the antenna, and the direction of the induced current on the metal structure is the same as that of the antenna. The direction of the current on it is opposite, which will weaken the working performance of the antenna to a certain extent

Abstract

The invention provides electronic equipment. The electronic equipment comprises an antenna and a metal structure which are accommodated in a shell; in a first direction, the metal structure, at least part of the antenna and part of the shell are arranged in sequence; the metal structure is provided with a non-closed slot, and the slot penetrates through the metal structure in the first direction; the metal structure comprises a first surface directly facing the antenna in the first direction, the vertical projection of the antenna on the first surface is an antenna projection area, and the slot extends from the edge of the first surface to the interior of the first surface and passes through the antenna projection area, thus, when the antenna is in a working state, induced current in the same direction as current on the antenna is formed on the first surface. By using the electronic equipment provided by the invention, due to the existence of the non-closed slot on the metal structure, the adverse effect of the induced current on the magnetic field of the antenna is reduced, and the working performance of the antenna is effectively improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an electronic device with an antenna. Background technique [0002] With the development of communication technology, electronic equipment has more and more functions, and there are more and more internal devices and communication antennas in electronic equipment. Compression will make the distance between the metal structure inside the electronic device and the antenna smaller. According to Lenz's law, an induced current will be generated on the metal structure close to the antenna, and the direction of the induced current on the metal structure is the same as that of the antenna. The direction of the current on the antenna is opposite, which will weaken the working performance of the antenna to a certain extent. [0003] Therefore, there is an urgent need for an electronic device that can change the adverse effect of the induced current on the metal struct...
