Problems solved by technology

[0003] When designing the antenna and circuit board layout, if the installation position of the metal electronic components on the circuit board just falls on the antenna design area, one solution is to move the metal electronic components to other areas of the circuit board, so that It is bound to cause changes in the wiring of the metal electronic components on the circuit board, resulting in design difficulties
Another solution is to design the antenna on the circuit board area far away from the metal electronic components. However, if the mounting position of the antenna is changed, the radiation efficiency of the antenna will be poor and the bandwidth will be narrowed.

The invention provides an electronic device. The electronic device comprises a multilayer circuit board, a main antenna portion and a metal electronic component, wherein the multilayer circuit board comprises a surface layer and a ground layer; at least a signal wire electrically connected to the metal electronic component is arranged on the multilayer circuit board; the main antenna portion is arranged on the surface layer of the multilayer circuit board and is electrically connected to the ground layer; the metal electronic component is arranged on the surface layer and is welded onto the main antenna portion; and the metal electronic component is grounded via the main antenna portion. The electronic device has the following advantage that: the main antenna portion has good radiation efficiency.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device in which metal electronic components are designed on an antenna. Background technique [0002] Generally, when designing an antenna, there must be a certain design space, and there must be no metal electronic components in this space, otherwise the radiation performance of the antenna will be affected. Especially when the metal electronic component is to be connected to the system ground through the wiring line on the circuit board, it will greatly affect the radiation performance of the antenna near it. Therefore, when designing the antenna of a traditional mobile phone, the antenna is designed to be exposed to ensure that the surrounding area of ​​the antenna will not be affected by metal electronic components. In order to pay attention to the beautiful appearance, the current antenna has been designed inside the mobile phone, and the design of the mobile phone is d...
