Abstract

The invention provides a back cover of an electronic device, which includes a metal body. The metal body has a first side, a second side adjacent to the first side, and a slot recessed in the first side. The metal body includes a first radiator, a second radiator and a ground radiator. The first radiator is located in the slot, and has a main body and a branch that together form a T-shape. The first radiator operates in a first frequency band. The body portion includes a feed-in end adjacent to the closed end of the slot. The second radiator is adjacent to the slot, defined by the first side, the second side and the edge of the slot, and operates in the second frequency band. The ground radiator is formed by a part of the metal body other than the first and second radiators. The second radiator and the branch are connected to the ground radiator. The first radiator, the second radiator and the ground radiator together serve as an antenna structure. An electronic device is also presented.

Description

technical field

[0001] The invention relates to a back cover and an electronic device, in particular to a back cover of an electronic device capable of forming an antenna structure and an electronic device using the back cover. Background technique

[0002] In recent years, the body of the notebook computer is mostly made of metal, and the appearance is usually designed with a narrow frame to provide a more beautiful appearance. In order to prevent the performance of the antenna from being affected by the shielding effect of the metal material, the current market practice is to install the antenna of the notebook computer in the system, but in this configuration, the antenna is easily interfered by the noise inside the system and directly affects the signal quality . Another approach is to support the antenna on the circuit board and move it to the sky side (bezel), but this will make it difficult to reduce the frame space of the display panel, which is not conducive to the...
