The present invention provides an electronic device, which comprises: a middle frame and a PCB board, the middle frame includes an inner frame and an outer frame, the outer frame and the inner frame are electrically connected through connecting ribs, and the outer frame is provided with A metal arm, the metal arm is electrically connected to the inner frame through the connecting rib, and the connecting rib divides the metal arm into a first antenna radiator and a second antenna radiator; the PCB board is provided with A conductive connecting piece and a grounding line, the conductive connecting piece is connected to the metal arm, the grounding line is electrically connected to the inner frame, and the grounding line is connected to the first antenna radiator through the conductive connecting piece The ground terminal of the second antenna radiator is electrically connected to the ground terminal. The embodiments of the present invention reduce the interaction between the first antenna radiator and the second antenna radiator, thereby enhancing antenna isolation.
Description
technical field [0001] The present invention relates to the technical field of communication equipment, in particular to an electronic equipment. Background technique [0002] With the development of communication technology, the Multiple-Input Multiple-Output (MIMO) antenna system has received more and more attention and has been applied to various electronic devices, which means that the requirements for the number of antennas continue to increase, and The electronic devices we use, such as smart phones, have limited design space, which brings about the contradiction between limited space and placing more antennas in it, and the isolation problem between antennas is becoming more and more prominent. In the existing technology, such as figure 1 As shown, the electronic device includes a middle frame 10 and a printed circuit board (i.e. a PCB board). The middle frame 10 includes an inner frame 11 and an outer frame 12. The outer frame 12 and the inner frame 11 are electrica...
