Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and specifically to an ultra-thin broadband antenna for PCBs. Background Technology

[0002] With the development of the communications industry and the improvement of people's living standards, as well as the increasing awareness of green environmental protection, the demand for aesthetically pleasing and concealed antennas is gradually increasing. Aesthetically pleasing and concealed antenna technology can reduce people's fear of electromagnetic radiation and can also blend in harmoniously with the surrounding environment. Existing indoor distributed antennas usually have metal or PCB elements inside, use a metal reflector, and are covered with an opaque white PVC cover, which is not concealed enough and is also relatively large and heavy. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this application is to provide an ultra-thin broadband PCB antenna that can effectively solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this application adopts the following technical solution: This solution provides an ultra-thin broadband antenna for PCBs, including: A substrate, the outer surface of which is covered with an ink layer. A radiation unit is disposed on the surface of the substrate. The cable unit includes a support base and a cable component, wherein the cable component is fixedly mounted on the surface of the substrate via the support base.

[0005] Furthermore, the radiating unit includes a first radiator and a second radiator, which are symmetrically arranged and integrated on the substrate.

[0006] Furthermore, the support base includes a support plate, which is attached to the surface of the substrate, and the support plate and the substrate are fixedly connected by rivets.

[0007] Furthermore, the support base includes a support column, which is fixedly mounted on the support plate, and the cable component is fixedly mounted on the support column by a cable fastening structure.

[0008] Furthermore, the cable assembly includes a first cable and a second cable, which are bound together by a cable clamp.

[0009] Furthermore, both the first radiator and the second radiator are covered with an ink layer.

[0010] Beneficial effects This application provides an ultra-thin broadband PCB antenna, which uses an ultra-thin PCB substrate and is covered with an ink layer. The color of the ink layer is consistent with the color of the wall and ceiling of the installation environment. The cross-section is ultra-thin and the size is small. No additional antenna cover is required. It is easy to blend into the background, has higher concealment, and is more suitable for the requirements of aesthetics and lightweight.

[0017] Example One embodiment of this application provides an ultra-thin broadband antenna for PCBs, such as... Figure 1 As shown, the antenna includes Substrate 1, with an ink layer covering its outer surface. A radiation unit is disposed on the surface of a substrate 1. The radiation unit includes a first radiator 2 and a second radiator 3, which are symmetrically arranged and integrated on the substrate 1. The cable unit includes a support base and a cable component. The cable component is fixedly mounted on the surface of the substrate 1 via the support base. The support base includes a support plate 4, which is attached to the surface of the substrate 1 and is fixedly connected to the substrate 1 via rivets 5. The support base also includes a support column 6, which is fixedly mounted on the support plate 4. The cable component is fixedly mounted on the support column 6 via a cable fastening structure 9. The cable component includes a first cable 7 and a second cable 8, which are bound together by a cable clamp 10.

[0018] Meanwhile, both the first radiator 2 and the second radiator 3 are covered with an ink layer. The antenna body is made of PCB material and covered with an ink layer. The color of the ink layer matches the background color of the installation environment; it can be white, gray, or other colors. The design eliminates the traditional radome and features an ultra-thin profile, making it easier to integrate with the ceiling. This antenna achieves excellent radiation performance and impedance matching in the 600-6000MHz ultra-wideband range. It can simultaneously provide dual 600-6000MHz ultra-wideband coverage with good isolation.
