Improved-type omnidirectional broadband discone antenna

Abstract

The invention discloses an improved-type omnidirectional broadband discone antenna, and the antenna comprises a bottom plate metal body, a feed connection column, a conical metal body, and a supporting rod. The lower end of the conical metal body is connected to the top of the supporting rod in a sleeved manner. The feed connection column is vertically disposed at the top of the conical metal body, and the bottom plate metal body is disposed at the top of the feed connection column. The bottom plate metal body is a cylindrical platform, and the periphery of the cylindrical platform is uniformly provided with bottom plate metal rod installation holes in a circle. The upper side of the conical metal body is provided with a circular truncated cone, wherein the upper part of the circular truncated cone is smaller and the lower part of the circular truncated cone is bigger. The lower side of the conical metal body forms an inverted circular truncated cone, wherein the upper part of the inverted circular truncated cone is bigger and the lower part of the inverted circular truncated cone is smaller. The inclined surface of the inverted circular truncated cone is provided with uniform conical metal rod installation holes in a circle. One side, close to the supporting rod, of the conical metal rod installation holes is provided with a rotating channel. The rotating channel takes the surface of the supporting rod as the channel wall, and the channel wall of the rotating channel is provided with a spring, wherein the inclination angle of the spring is 60-80 degrees. According to the invention, the installation and recycling process of the discone antenna is simplified, and the recycling efficiency of the discone antenna is also improved, and the man-made damage rate is reduced.

Description

technical field [0001] The invention relates to the field of antenna communication, in particular to an improved omnidirectional broadband disc-cone antenna. Background technique [0002] In recent years, with the development of mobile communication technology, the demand for ultra-wideband antennas is also increasing, and ultra-wideband antennas have gradually become a research hotspot. The dish cone antenna not only has ultra-wideband characteristics, almost uniform angular coverage, but also has the advantages of small size (compared with the biconical antenna, the volume is reduced by half), simple fabrication, and low cost. Therefore, the dish cone antenna has a very good development prospect. Disk cones are evolved from double cones. Increase the cone angle of the upper cone of the double cone to 180°, and the upper cone becomes a disc. According to the ideal ground equivalent principle, disc cones have the same performance characteristics as bicones. Without reduc...

Problems solved by technology

However, in the prior art, the conical metal rods are connected to the conical metal body by threads, so that the dish cone antenna needs to be manually rotated and removed from the cone metal body when the dish cone antenna is not in use, which will not only cause the dish cone antenna The recovery efficiency is low, and it may also cause damage to the cone metal rod or cone metal body during the manual recovery process
