Abstract

The invention relates to a miniature wireless local area network (WLAN) dual-frequency PIFA antenna. An antenna radiation unit comprises a grounding line, a feeder, a first branch wire and a second branch wire, wherein the grounding line, the feeder, the first branch wire and the second branch wire are attached onto a surface of an antenna support to form an antenna assembly, the grounding line ofthe antenna radiation unit is achieved by a relatively narrow wire, the first branch wire of the antenna radiation unit extends from the feeder, the second branch wire of the antenna radiation unit employs a U-shaped wire which is narrow in front part and wide in rear part, an antenna wiring form of the antenna radiation unit employs the U-shaped wire, the feeder is connected with a feeding source and the antenna radiation unit, and the grounding line is connected with a printed circuit board and the antenna radiation unit. A WLAN dual-frequency mobile terminal antenna is achieved by a miniaturization technology, the space can be effectively utilized, frequency coverage of 2.4GHz WLAN and 5GHz WLAN is achieved on the basis of integral miniature product, so that high-efficiency antenna radiation of WLAN dual frequencies is achieved.

Description

technical field [0001] The field of antenna technology related to the antenna of the present invention is specifically a miniaturized WLAN dual-band antenna in a no-clearance environment, which uses space multiplexing to realize dual-band antenna radiation, and reduces the space occupied by the antenna while requiring no clearance. Background technique [0002] Modern wireless communication equipment requires WLAN antenna design in as small a space as possible to achieve more functions. In order to meet the dual-band requirements of WLAN (wireless local area network) IEEE 802.11 series 2.4 GHz (2.4GHz-2.5 GHz), 5 GHz WLAN (4.9GHz–5.85 GHz), the traditional WLAN antenna design technology mainly places the antenna position on the motherboard Edge clearance area, and ensure sufficient antenna routing area. In order to meet the requirements of dual-band coverage, the traditional design scheme needs to ensure that the product retains a certain clearance area and wiring area, whi...
