A corrosion-resistant antenna for communication technology

Abstract

A corrosion-resistant antenna for communication technology is disclosed, comprising an antenna base, a handle is mounted on the outer surface of one side of the antenna base, and one end of the handleis fixedly connected with a first bevel gear through a circular rod, the outer surface of the first bevel gear is meshed with and connected with a second bevel gear, and a turntable is connected withthe center of the top surface of the second bevel gear through a circular rod. In this invention, first, through a mesh flow groove composed of a plurality of first drainage grooves and a second drainage groove, when rain or other liquids fall on the outer surface of the annular focal reflecting surface, and secondly, by rotating the handle to drive the first bevel gear, the second bevel gear andthe turntable to rotate, the position and the angle of the ring-focus reflector can be easily adjusted, and the rust probability of the connection part can be greatly reduced by the protective sleevesleeved on the outer surface of the bottom of a support.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a corrosion-resistant antenna for communication technology. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the sam...

Problems solved by technology

[0003] The structure of the traditional antenna is simple. In rainy weather, rainwater often falls on the outer surface of the antenna. Since the antennas on the market are rarely made of waterproof structures, when rainwater accumulates on the outer surface of the antenna and fails to flow out in time, it is very easy to damage the antenna. The outer surface is rusted and corroded. Now, the bracket connected to the bottom of the antenna and the base are mostly connected by bolts. However, the bolts are exposed to the environment for a long time, and they often get rusted due to water ingress. It is also more troublesome to fix the rusty bolts. After a long time, the bolts will break
