Abstract

The invention relates to a novel wide-band PCB antenna suitable for wireless local area network WLAN, including a printed circuit board and an antenna radiation unit, the antenna radiation unit is located on the printed circuit board, and the printed circuit board as a whole serves as an antenna system, and the ground wire Located at the edge of the antenna radiation unit and the printed circuit board, the first radiator is arranged on the side of the ground wire, the second radiator, the ground wire, and the third radiator form a broadband loop antenna; the third radiator The fourth radiator forms a coupling with the lower metal formation plate; the fourth radiator is used as a branch line of the antenna radiator, and is located at the angle between the two sides of the metal formation plate. Utilize the three principles of loop antenna formation, antenna branch wiring and antenna ground coupling to achieve broadband radiation impedance, so as to achieve effective antenna radiation in the ultra-wide range from 1.36GHz to 8GHz, covering WLAN 2.4GHz and 5GHz frequency bands, and It has strong robustness to the surrounding environment of the antenna.

Description

technical field [0001] The invention belongs to a WLAN broadband PCB antenna suitable for a wireless local area network, in particular to a WLAN dual-band antenna realized by using broadband technology. Background technique [0002] Wireless Local Area Network, WLAN uses radio frequency technology to replace old cables with electromagnetic waves to form a wireless data transmission network, which is widely used in smartphones, tablet computers and other communication devices. Wireless local area network users can connect to the wireless access node Access Point, AP through the handheld device, thereby accessing the wireless local area network. The AP antenna in the WLAN is an important part of the entire communication system. Common AP built-in WLAN antennas are mostly attached to PCB boards. This traditional built-in AP antenna is greatly affected by the environment. In order to be used for WLAN network coverage in different places, AP devices often need to be distributed...
