Description

Technical Field

[0001] The invention relates to the field of communication technology, in particular to a four-port transparent broadband omnidirectional 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 provides wireless communication functions without affecting the appearance. Compared with traditional antennas, transparent antennas are more concealed and beautiful; existing ordinary omnidirectional antennas are usually made of metal or PCB materials, plus an outer cover, which is thick and not concealed enough, affecting the beauty of the interior of the building, and generally have a single port or two ports, and the coverage capacity is insufficient. For this reason, we propose a four-port transparent broadband omnidirectional antenna. Summary of the invention

[0003] The object of the present invention is to provide a four-port transparent broadband omnidirectional antenna to solve the problems raised in the above background technology.

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

[0005] A four-port transparent broadband omnidirectional antenna comprises a connector assembly, wherein a plastic part is connectedly arranged at the bottom of the connector assembly, a radiator is arranged at the bottom of the plastic part, welding seats are arranged around the top of the radiator, an antenna film is arranged at the bottom of the radiator, optical glue is arranged at the bottom of the antenna film, a plastic support plate is arranged at the bottom of the optical glue, a plastic part upper cover is arranged at the bottom of the plastic support plate, a large radiator is arranged at the top center of the radiator, small radiators are arranged around the top of the radiator, and the welding seats are located around the top of the large radiator and correspond to the positions of the small radiators.

[0006] Furthermore: the antenna film is a transparent antenna film, and the transparent antenna film is a PET material film with low square resistance, and the radiator is adhered to the antenna film.

[0007] Furthermore: the plastic support plate is set as a transparent support plate, and the transparent support plate is a PC material or acrylic material with good light transmittance, and the antenna film is fixed on the plastic support plate by optical glue.

[0008] Further: the plastic part includes a plastic part lower cover matched with the plastic part upper cover, and a screw is arranged at the top center of the plastic part lower cover.

[0009] Furthermore: an asymmetric double cone is formed around the large radiator and between the small radiator, and the radiation sheets on the large radiator and the small radiator are both made of metal mesh.

[0010] Furthermore: there are two groups of connector components, and each group of connector components includes a feeder cable, and a connector is provided at one end of the feeder cable away from the plastic component.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This four-port transparent broadband omnidirectional antenna has the following features: 1. Good light transmittance and beautiful appearance; 2. Ultra-thin and miniaturized, and capable of achieving ultra-broadband; 3. 4T4R array form, which can improve capacity and transmission efficiency;

[0013] The radiator consists of a large and four small radiating units, a total of five radiating units. The radiating sheet adopts a metal mesh method, and each radiating unit is provided with a pad. The feeding branches extending from the small radiating unit are embedded in the large radiating unit to form a coupling effect. By changing the embedding depth and gap, the impedance can be changed, which is conducive to impedance matching in the ultra-wide frequency band of 600MHz-7500MHz. The four small radiating units are distributed around the large radiating unit.

[0014] In this distribution mode, the large radiation unit forms an asymmetric double cone shape for each small radiation unit, which is equivalent to a four-in-one common body, which can effectively reduce the area and achieve miniaturization and broadband.

[0015] The four ports are fed by four cables respectively. The inner core of the cable is welded to the pad of the small radiation unit, and the outer conductor is welded to the pad of the large radiation unit through a connecting seat.

[0016] The four ports can realize 4T4R working status, which can effectively expand the bandwidth capacity and improve the coverage effect. BRIEF DESCRIPTION OF THE DRAWINGS
