[0002] In the existing antenna installation structure, in order to ensure good signal reception at the same time, the antenna needs to be as close as possible to the housing of the product. And in order to reduce costs, an antenna flexible circuit board is usually used as the antenna of the product. In order to install the antenna on an electronic device, a through groove is usually provided on the frame of the electronic device, and the antenna flexible circuit board is passed through the through groove. The antenna flexible circuit board is bent so that both ends of the antenna flexible circuit board are respectively arranged on the inner side surface and the outer side surface of the frame. A shrapnel is provided on the main board of the electronic device, and the shrapnel is in abutting connection with the antenna flexible circuit board on the inner side surface of the frame. When the shrapnel is connected to the antenna flexible circuit board and the main board, the antenna flexible circuit board and the main board approach each other so that the shrapnel is pressed, ensuring that the shrapnel maintains stable contact with the antenna flexible circuit board and the main board. The pressed shrapnel exerts a force on the antenna flexible circuit board, and the antenna flexible circuit board needs to be attached to the inner side surface of the frame, so that the frame forms reinforcement for the flexible circuit board, maintaining the stable contact between the shrapnel and the antenna flexible circuit board, and preventing the shrapnel from piercing the flexible circuit board.

The elastic piece 5 on the main board is inserted into the communication groove 31, and the end of the elastic piece 5 away from the main board is connected to the feeding point portion on the antenna flexible circuit board 1. The rear cover 4 is connected to the housing 3 so that the back glue member 41 fits on the portion of the antenna flexible circuit board outside the support plate 2. The main board is electrically connected to the antenna flexible circuit board 1 through the elastic piece 5, so that the main board can send and receive signals through the antenna flexible circuit board 1.
