Description

Technical Field

[0001] The invention relates to the field of communication technology, and in particular to a directional transparent antenna. Background Art

[0002] With the development of the communications industry and the improvement of people's living standards, the awareness of green environmental protection has increased, and the demand for beautification and concealment of antennas is gradually increasing. Beautification and concealment of antenna technology can reduce people's fear of electromagnetic radiation, and at the same time be able to blend in with the surrounding environment. Transparent antenna technology not only has unique transparency, but also can provide wireless communication functions without affecting the aesthetics. Compared with traditional antennas, transparent antennas are more concealed and beautiful; existing directional base station antennas usually have metal vibrators or PCB vibrators inside, a metal reflector, and an opaque outer cover such as PVC or fiberglass. They are not concealed enough and are large in size and weight. The mounting bracket used in traditional small base stations usually has a mechanically adjustable tilt angle of 0-25°, and the horizontal tilt angle cannot be adjusted, which cannot meet the increasingly flexible coverage effect. For this reason, we propose a directional transparent antenna. Summary of the invention

[0004] To achieve the above object, the present invention provides the following technical solutions:
