Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and more specifically to a transparent window sill antenna. Background Technology

[0002] With the development of the communications industry and the improvement of people's living standards, coupled with increased awareness of green environmental protection, the demand for aesthetically pleasing and concealed antennas is gradually increasing. Aesthetically pleasing and concealed antenna technologies can reduce people's fear of electromagnetic radiation while blending harmoniously with the surrounding environment. Transparent antenna technology not only possesses unique transparency but also provides wireless communication functionality without compromising aesthetics. Compared to traditional antennas, transparent antennas offer superior and more stable performance, a more concealed and aesthetically pleasing appearance, and more flexible and convenient installation and use. Existing ordinary indoor antennas are typically made of metal or PCB materials with an outer cover, resulting in significant thickness, making concealed installation difficult and affecting aesthetics, especially in high-end venues and hotels. Existing ultra-thin antennas (such as patch antennas) reduce thickness but sacrifice performance (lower gain, narrower bandwidth). Existing traditional antennas require multiple independent antennas to cover 2G / 3G / 4G / 5G frequency bands (such as 700MHz~3.5GHz), leading to complex structures and increased size.

[0019] Example One embodiment of this application provides a transparent window sill antenna, such as... Figures 1-2 As shown, the antenna includes: Support plate 1, comprising a rectangular transparent plate, serves as the main support structure for the antenna. It is made of materials with good light transmittance, such as PC (polycarbonate), acrylic, transparent nylon, glass, and graphene, with a light transmittance approaching 90%. Multiple suction cups 2 are fixedly mounted on the surface of support plate 1, evenly distributed in a rectangular shape along the edges of the support plate 1 surface. The suction cups 2 are made of transparent materials with good light transmittance, such as silicone, rubber, polyurethane (PU), and TPE / TPR (thermoplastic elastomer). One end of the suction cup 2 is fixed to the transparent support plate 1 (not shown in the figure) by a clip, while the other end adheres to glass or a wall. Antenna film 3, comprising a rectangular transparent film, is made of low sheet resistance PET material. Low sheet resistance effectively reduces transmission loss and helps improve antenna gain. Antenna film 3 is attached to the surface of support plate 1 opposite to suction cup 2 and can be fixed by optical adhesive 12. The radiator 4 comprises two elements, arranged vertically, attached to the surface of the antenna diaphragm 3 facing away from the support plate 1. Each radiator 4 includes a first radiating element 41 (large radiating plate) and a second radiating element 42 (small radiating plate). The radiating sheet adopts a metal mesh structure with the mesh arranged horizontally and vertically. Compared with traditional PCB + copper foil and metal, it has better light transmittance without affecting performance. The surface of the radiating sheet's pads is coated with a matte inert metal layer, silver-gray, which is easy to solder and ensures the product's low intermodulation characteristics. The inner core of the feed cable is soldered to the pads of the first radiating unit 41, and the signal connector 9 is soldered to the pads of the second radiating unit 42 via the soldering socket 8. The feed branch 5 extending from the first radiating unit 41 is embedded inside the second radiating unit 42 to form coupling. Both the first and second radiating units 41 and 42 have cutouts 6. The first radiating unit 41 has a matching branch 7. The inner core of the feed cable is soldered to the pad of the large radiating unit, and the outer conductor is soldered to the pad of the small radiating unit via a connector. The feed branch 5 extending from the large radiating unit is embedded inside the small radiating unit to form coupling, which is beneficial for impedance matching in the ultra-wideband frequency range of 600MHz-6000MHz. Both the large and small radiating units have cutouts, and the large radiating unit has matching branches 7, which can improve the current distribution between the radiators 4, thereby achieving miniaturization and broadband operation. The welding seat 8 is located on the surface of the radiator 4 that is away from the antenna film 3, and the signal connector 9 is fixedly welded to the welding seat 8.

[0020] The surface of the support plate 1 where the suction cup 2 is located is also provided with a first fixing seat 10. The first fixing seat 10 is fixedly connected to the support plate 1 by screws. The side of the radiator 4 where the welding seat 8 is located is also provided with a second fixing seat 11. The second fixing seat 11 is fixedly connected to the welding seat 8 and snaps onto the top of the signal connector 9. The first fixing seat 10 and the second fixing seat 11 are both made of plastic structural components. This transparent antenna is in the form of a thin sheet, small in size, and has good light transmission. It can be placed inside the building and provides wireless communication function without affecting the aesthetics.

[0021] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
