E-band high-performance antenna

Abstract

The invention relates to the technical field of a microwave antenna, and specifically relates to an E-band high-performance antenna, comprising a reflective surface, an antenna cover and a feed source; the feed source comprises a feed source base, a waveguide tube, radiation dielectric and a secondary reflective surface; a through hole is formed in the central position of the feed source base; a waveguide port is formed in one, positioned on the exterior of the reflective surface, of the through hole, and the waveguide tube is inserted in one end positioned in the inner cavity of the reflective surface; the radiation dielectric adopts a T-shaped structure, and comprises lower part dielectric inserted in the waveguide tube and opposite to one end of the feed source base, and upper part dielectric arranged on the exterior of the waveguide tube; an annular groove is formed in the outer edge of the lower part dielectric; at least one layer of annular stage is arranged on the outer edge ofthe upper part dielectric; a conical groove is formed in the end plane, opposite to the lower part dielectric, of the upper part dielectric; and the secondary reflective surface is matched with the conical groove in shapes and attached in the conical groove. The E-band high-performance antenna is simple and convenient to mount, easy to produce, low in cost, low in dielectric loss and high in frequency band.

Description

technical field [0001] The invention relates to the technical field of microwave antennas, in particular to an E-band high-performance antenna. Background technique [0002] Microwave is the most commonly used wireless communication technology at present. It has long transmission distance, large capacity, fast deployment and strong stability. It is now widely used in the relay and backhaul of various communication systems. At present, conventional 6GHz-38GHz microwave spectrum resources have been rapidly exhausted, and E-band (71GHz-86GHz) microwave frequency band will be an important means of wireless transmission. In order to pursue the characteristics of miniaturization and easy integration, E-band flat panel technology is being extensively studied. The planar array antenna is made in the form of SIW or waveguide slot array, the radiation unit is small, and the antenna profile is greatly reduced. Low; the traditional waveguide slot array adopts the form of series feed, ...
