Description

Technical Field

[0001] The invention relates to the field of communication technology, in particular to a broadband transparent vibrator. 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 appearance. Compared with traditional antennas, transparent antennas are more concealed and beautiful; existing directional base station antennas usually have metal vibrators or PCB vibrators inside, use 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. For this reason, we propose a broadband transparent vibrator. Summary of the invention

[0003] The object of the present invention is to provide a broadband transparent vibrator to solve the problems raised in the above background technology.

Two groups of vibrator plates are arranged in a cross shape on the top of the balun. Support columns are arranged at both ends of the tops of the two groups of vibrator plates. Parasitic unit plates are installed on the tops of the two groups of vibrator plates through the supporting columns. Coupling strata are arranged on both sides of the top center of the vibrator plate, and radiation surfaces are arranged on both sides of the bottom of the vibrator plate.

[0006] Furthermore: the balun includes balun 1 and balun 2, balun 1 and balun 2 are arranged in a cross shape at the top center of the bottom plate, and the angles between the balun and the bottom plate and the vibrator plate are all set to 90 degrees.

[0007] Furthermore: the top and bottom of Balun 1 and Balun 2 are both provided with card blocks, and the top center of the bottom plate and the center of the two groups of vibrator pieces are both provided with card slots matching the card blocks.

[0008] Furthermore: the parasitic unit plates are all single-sided transparent film structures, and are located above the oscillator plate.

[0009] Further: the bottom plate is set as a square bottom plate, and the bottom plate is set as a PC material plate or an acrylic material plate.

[0010] Furthermore: the support columns are all configured as plastic support columns, the top and bottom of the plastic support columns are both provided with connection holes, and the positions of the vibrator plate and the parasitic unit plate corresponding to the support columns are both provided with fixing holes matching the connection holes.

[0011] Furthermore: the top of the bottom plate is vertically hung with mounting holes around it.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The broadband transparent vibrator, the transparent vibrator of the present invention, has high light transmittance. When combined with a transparent antenna cover, the entire base station antenna can become highly transmittance, highly concealed, and have a decoupling effect. It is suitable for multi-frequency environments and miniaturization requirements.
