Abstract

The invention provides an electronic system. The electronic system comprises a display device and a data processing device, wherein the display device is connected with the data processing device and is provided with an antenna and a metal framework; the data processing device is provided with a coaxial cable extending to the display device; the coaxial cable is coupled with the antenna and feedsa signal in the antenna from the data processing device; and a part of a metal shielding layer of the coaxial cable is stripped and exposed and electrically connected with the metal framework through an electric conduction adhesive plaster, and the electric conduction adhesive plaster is longer than the 1 / 120 wave of the antenna high frequency centre frequency, so as to inhibit reverse current so as to improve the radiation efficiency of the antenna.

Description

technical field [0001] The invention belongs to the field of electronic systems with built-in antennas in screens, and in particular relates to an electronic system in which a metal shielding layer of a coaxial cable for transmitting antenna signals is partially exposed and electrically connected to a metal frame of a display screen. Background technique [0002] At present, with the advancement of wireless communication system integration, notebook computers with built-in antennas for wireless transmission have become popular. Most of the built-in antennas are arranged in the screen of the notebook computer, and the transmitter module transmits signals to the antenna through the coaxial cable. Since the overall assembly structure of the antenna and the coaxial cable is in an unbalanced mode, there will be a reverse current flowing on the metal shielding layer (shielding) of the coaxial cable during actual operation, making the coaxial cable in the notebook When the wires a...
