Description

Technical Field

[0001] The utility model relates to the technical field of communication antennas, in particular to a windproof antenna. Background Technique

[0002] An antenna is a transducer that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or performs the reverse conversion. It is a component used to transmit or receive electromagnetic waves in a radio device. In engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, and radio astronomy, all of 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 an antenna. Generally, an antenna has reversibility, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna.

[0003] However, there are still deficiencies in the prior art. When the existing antenna is used outdoors and encounters strong wind, the existing antenna is easily blown off, thus affecting the normal operation of the antenna and reducing the practicability of the existing antenna.

[0004] Therefore, we propose a windproof antenna to solve this problem. Summary of the Invention
