Abstract

The invention discloses a Q-wave band ultra-high-speed wireless local area network mobile terminal antenna, which comprises a dielectric substrate, a rectangular metal antenna radiation unit, a short circuit branch metal strip, a feeder branch metal strip and a metal grounding plane, wherein the short circuit branch metal strip and the feeder branch metal strip are connected with the antenna radiation unit, a first metal through hole is formed in the short circuit branch metal strip, a second metal through hole is formed in the feeder branch metal strip, the area of the metal grounding plane covers the area of the antenna radiation unit, the short circuit branch metal strip and the feeder branch metal strip, and a U-shaped gap is formed in the rectangular metal antenna radiation unit. Compared with the prior art, the Q-wave band ultra-high-speed wireless local area network mobile terminal antenna has the advantages that by aiming at the characteristics of the millimeter wave frequency band (45GHz), a printed circuit process is utilized for designing and realizing the Q-wave band mobile terminal antenna with simple structure and small size, the antenna has the characteristics of broadband, small standing wave, omnidirectional radiation, easy integration, higher precision and good repeatability, meanwhile, the cost is low, the batch production is convenient, and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a Q-band ultra-high-speed wireless local area network mobile terminal antenna. Background technique [0002] Based on the sufficient spectrum resources in the millimeter-wave frequency band, the development and development of a new generation of ultra-high-speed wireless LAN communication standards and systems is becoming an important direction for the future development of wireless communication networks. According to the frequency planning of the Ministry of Industry and Information Technology of my country, the 42.4-48.4GHz spectrum resources in the Q-band have been designated as ultra-high-speed wireless LAN services and announced at the end of 2013. The communication standardization work related to this frequency spectrum is being carried out extensively. Among them, the 802.11aj (45GHz) standard working group was established in 2012 with the permission of the...
