Abstract

The invention discloses an electronic device. The electronic device includes a metal casing and at least one switch. The metal casing includes a peripheral frame, and at least one micro-slit strip is arranged on the peripheral frame. The at least one micro-slit The belt divides the peripheral frame into at least one frame body, the micro-slot belt is formed by at least two micro-slits arranged at intervals, and there is a metal part between two adjacent micro-slots, and the switch includes a first end and a second end, the first end is electrically connected to the frame body divided by the micro-slit strip, the second end is electrically connected to the metal part, wherein the at least one micro-slit strip is divided to form At least one section of the frame is an independent antenna. The electronic device of the present invention can expand the low-frequency bandwidth of the antenna of the electronic device and increase the degree of freedom of antenna performance debugging.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an electronic device. Background technique [0002] The appearance design of metal material is more textured, so mobile phones using metal casings gradually occupy the mainstream of the market. The appearance of the metal casing broke the design idea of ​​the traditional mobile phone antenna and greatly increased the difficulty of antenna design. In the prior art, it is considered to use the metal case as a part of the antenna, and use the metal case for signal radiation. With the evolution of mobile communication technology, more and more frequency bands are applied to mobile terminals, which requires mobile phone antennas to have good compatibility and work on multiple frequency bands at the same time. However, the current mobile phone antennas with metal casings often have insufficient low-frequency bandwidth to meet the requirements of communication systems. C...
