Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, a Q-band ultra-high-speed wireless local area network indoor access antenna includes a radiation unit 1 and a feeder unit 2, and the two parts are printed on the same dielectric substrate using printed circuit technology.

[0024] An acute-angled metal strip is printed on the upper surface and the lower surface of the dielectric substrate where the radiation unit 1 is located, wherein the included angle of the acute-angled metal strip is between 30°-38°. The upper metal strip 11 is on the upper surface of the dielectric substrate, and the lower metal strip 12 is on the lower surface of the dielectric substrate. The projections of the upper metal strip 11 and the lower metal strip 12 on the dielectric substrate plane are mirror symmetric, showing Umbrella-shaped distribution, and the 'umbrella handles' are partially overlapped to form a parallel double-line structure, and the upper metal strip 11 and the lower metal strip 12 form an an...

Abstract

The invention discloses a Q-band superspeed wireless local area network indoor access antenna which comprises a radiating element and a feeder line part. The radiating element and the feeder line part are printed on a same medium substrate through the printed circuit technology. The radiating element is formed by printed umbrella-shaped symmetrical dipoles and a printed guide unit, the substrate is used for integrating a waveguide to achieve differential feed, an inductive window structure is loaded to achieve broadband impedance matching, and mutual connection with an external circuit can be achieved through the antenna mode by adopting a coplanar waveguide changeover structure or a substrate integrated waveguide changeover structure. Considering the requirements of the new generation Q-band superspeed wireless local area network standard and the related millimeter wave indoor communication system standard 802.11aj (45GHz), the access antenna which is provided with a wide working band (42.4-48.5 GHz), and wide beam coverage larger than or equal to 120 degrees in a main tangent plane and is capable of being integrated with a plane active millimeter wave circuit is achieved through the printed circuit technology.

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 indoor access antenna. Background technique [0002] The millimeter wave frequency band has the characteristics of abundant available spectrum resources and high data transmission rate. It has been widely concerned by the industry and has begun to develop related ultra-high-speed communication systems. 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 International Institute of Electrical and Electroni...
