Abstract

The invention provides an all-metal laptop antenna. The antenna comprises a bracket, an antenna body and an impedance matching circuit. As a kerf is formed in an all-metal substrate of an all-metal laptop, the antenna body is structurally divided into two parts which are arranged on the two sides of the bracket in a covering mode; in combination with the impedance matching circuit, a metal frame arranged above the kerf plays a role in radiating a low-frequency signal, and the antenna body plays a role in constructing a high-frequency resonance wave. The all-metal laptop antenna has better adaptability to the working environment of the antenna, is suitable for application in the situation that the antenna constraining environment is poor and can well meet the communication requirement of the all-metal ultra-thin laptop. The antenna of the gap-type metal laptop is low in return loss and high in working efficiency, and the space occupied by the antenna is effectively reduced; accordingly, the antenna provides favorable conditions for further miniaturization design of the metal laptop provided with the antenna structure.

Description

technical field

[0001] The invention relates to a radio frequency antenna, in particular to an all-metal notebook computer antenna. Background technique

[0002] With the continuous progress of society and the rapid development of science and technology, notebook computers have become an indispensable part of people's office life, and surfing the Internet is the main content of computer users. For portable notebook computers, the strong wireless signal Weakness is the key to the quality of Internet access. For the notebook computer itself, the ability to receive wireless signals is particularly important.

[0003] However, the current notebook computers are gradually becoming thinner and more fashionable, leaving less and less space for antennas. At the same time, notebook computers have gradually supported 3G, 4G and other communication protocols from simply supporting WIFI and Bluetooth to achieve Internet access anytime, anywhere. call. In addition, in order to pursue d...
