Abstract

The invention discloses a double-frequency high-isolation multiple input multiple output (MIMO) directional antenna applied to a wireless local area network (WLAN), belonging to the technical field of an antenna. The MIMO directional antenna comprises a grounding plate (1) and an antenna unit (2), wherein the antenna unit (2) is provided with a grounding pin (21), a feeding pin (22), a first radiation sheet (23), a second radiation sheet (24) and a third radiation sheet (25), the first radiation sheet (23) and the second radiation sheet (24) are connected with the third radiation sheet (25) by a bending part (26) to form a staggered layer structure, and the grounding plate (1) is connected with a reflecting plate (8) by a short-circuit probe (5). The antenna unit disclosed by the invention adopts the staggered layer structure, so that impedance matching and broadband are favorably achieved; an air layer is formed between the antenna unit and the grounding plate, and the loss of the electromagnetic wave is prevented from generating through a medium; and moreover, the whole antenna is simple in design and has a small volume, and high isolation is achieved during ceiling installation.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-frequency high-isolation MIMO directional antenna for WLAN. Background technique [0002] Wireless Local Area Network (WLAN) antenna is one of the key components of WLAN communication system, and its performance has a great influence on the quality and distance of wireless communication. In recent years, although wireless local area network technology has developed rapidly, its performance and speed still have a certain gap with people's expectations. How to further improve the performance and capacity of wireless local area network is becoming increasingly important. The new generation of wireless local area network standard adopts MIMO technology as its core technology, so as to further improve the throughput, transmission distance and reliability of WLAN. [0003] Although MIMO technology has been applied in WLAN systems, so far, an important factor that has not yet a...
