Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a green transparent omnidirectional base station antenna. Background Art

[0002] With the development of the communications industry and the improvement of people's living standards, green environmental awareness is increasing, and the demand for beautified and concealed antennas is gradually increasing. Beautified and concealed antenna technology can reduce people's fear of electromagnetic radiation and at the same time be able to blend in harmoniously with the surrounding environment. Transparent antenna technology not only has a unique transparency, but also provides wireless communication functions without affecting the aesthetics. Compared with traditional antennas, transparent antennas are more concealed and beautiful. Existing base station antennas usually have metal oscillators or PCB oscillators inside, use a metal reflector, and are covered with opaque PVC or fiberglass. These are not concealed enough, and their large size and weight affect the aesthetics of the surrounding environment. To this end, we propose a green, transparent, omnidirectional base station antenna. Summary of the Invention
