[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 appearance. Compared with traditional antennas, transparent antennas are more concealed and beautiful; existing base station antennas usually have metal vibrators or PCB vibrators inside, using a metal reflector plate, plus an opaque outer cover such as PVC or fiberglass, which is not concealed enough and has a large size and weight. For this reason, we propose a green transparent broadband vibrator. Summary of the invention
