Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication equipment technology, and in particular to an LDS antenna. Background Technology
[0002] LDS, or Laser Direct Structuring (LDS), is one of the most popular and advanced antenna manufacturing technologies. It offers numerous advantages, such as eliminating the need for molds and masks, allowing direct fabrication of circuit patterns using CAD data, high forming speed, and high processing resolution. The key to LDS technology lies in the use of special LDS functional plastics. Laser-activated additives are added to engineering plastics, and a computer-controlled laser beam moves across the plastic part to activate the surface where conductive paths are desired. Electroplating then selectively forms the desired conductive patterns on the plastic part. This direct laser structuring method allows for the achievement of narrow conductive path widths, which is particularly important for high-frequency, high-speed communications such as 5G. Currently, in the fabrication of LDS antennas, the process typically involves first injection molding the LDS material into a support structure, followed by electroplating, and then assembling electronic components onto the antenna traces using surface mount technology (SMT). This molding process, which involves directly laser etching the antenna pattern onto the antenna bracket, requires a large amount of LDS material, resulting in high costs. Furthermore, the bracket structure is quite large, and welding becomes difficult when the bracket is uneven. This also makes it inconvenient to connect and disassemble the LDS antenna. Utility Model Content
[0003] The purpose of this invention is to provide an LDS antenna that is easy to connect and disassemble and has low cost.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An LDS antenna includes: an antenna body plate and an antenna support plate, wherein the antenna body plate and the antenna support plate are detachably connected.
[0006] Preferably, a protrusion is provided on one side of the antenna body plate, and a groove is provided on one side of the antenna support plate, wherein the protrusion corresponds to and is matched with the groove for engaging.
[0007] Preferably, both the protrusion and the groove are in the shape of an "I".
[0008] Preferably, the groove is provided with a through screw hole.
[0009] Preferably, the upper and lower sides of the groove are provided with through screw holes.
[0010] The second screw hole corresponds to the first screw hole;
[0011] Bolts pass through screw hole two and screw hole one to fix the antenna bracket plate to the antenna body plate.
[0012] Preferably, the antenna support plate is provided with a camera window.
[0013] Preferably, the antenna body plate has a wiring area, and the antenna body plate is made of LDS functional plastic.
[0014] Preferably, the antenna support plate is made of ordinary plastic.
[0015] Preferably, the other side of the antenna support plate is also provided with mounting screw holes.
[0016] The beneficial effects of this utility model are:
[0017] This utility model provides an LDS antenna in which the antenna support plate and the antenna body plate are connected by snap-fit and bolt fixing, which makes the LDS antenna structure easy to install and disassemble, convenient for maintenance and debugging, and has high connection stability. At the same time, only the antenna body plate is made of LDS functional plastic, which greatly reduces material costs. Attached Figure Description
[0018] Figure 1 This is a three-dimensional structural schematic diagram of an LDS antenna according to the present invention;
[0019] Figure 2 This is a top view of an LDS antenna shown.
[0020] The components in the attached diagram are labeled as follows:
[0021] 10. Antenna bracket plate; 11. Groove; 12. Screw hole one; 20. Antenna main body plate; 21. Raised groove; 22. Screw hole two; 30. Camera window; 40. Mounting screw hole; 50. Antenna pattern. Detailed Implementation
[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0023] Example:
[0024] This embodiment describes the structure of an LDS antenna.
[0025] See Figure 1 , 2 As shown, Figure 1This is a three-dimensional structural diagram of an LDS antenna according to this utility model. Figure 2 This is a top view of an LDS antenna. An LDS antenna includes: an antenna support plate 10 and an antenna body plate 20, wherein the antenna body plate 20 and the antenna support plate 10 are detachably connected.
[0026] The antenna support plate and the antenna body plate are detachably connected in the following way: a "I"-shaped groove 11 is provided on one side of the antenna support plate 10, and a "I"-shaped protrusion 21 is provided on one side of the antenna body plate 20. The protrusion 21 corresponds to the groove 11 to achieve a snap-fit connection.
[0027] To further ensure a stable connection between the antenna body plate and the antenna support plate, the upper and lower sides of the groove 11 are provided with through screw holes 22, and the protrusion 21 is provided with through screw holes 12; the screw holes 22 correspond to the screw holes 12; the antenna support plate 10 and the antenna body plate 20 are fixedly connected by bolts passing through the screw holes 22 and the screw holes 12.
[0028] The installation of grooves, slots, and screw holes makes it easier to install and disassemble the antenna bracket plate and the antenna body plate. This solves the problem in the prior art where electronic components are soldered onto the antenna bracket, which is large and difficult to solder. Moreover, the above connection method is also convenient for maintenance and debugging, and the connection stability is high.
[0029] Furthermore, a camera window is provided on the antenna support plate to accommodate the camera.
[0030] To address the high material cost of LDS antennas in existing technologies, this embodiment uses LDS functional plastic as the material for the antenna body plate and ordinary plastic as the material for the antenna support plate. Both the ordinary plastic and the LDS functional plastic use the same matrix resin, which can be polycarbonate resin or a modified resin material based on polycarbonate resin. In this embodiment, the antenna support plate can be made of ordinary polycarbonate resin, while the antenna body plate can be made of polycarbonate resin LDS functional plastic, meaning it contains LDS laser-activated additives. A wiring area is provided on the antenna body plate. When the antenna body plate is irradiated with a laser, the metal particles in the material are activated by the laser, and then an antenna pattern 50 is formed on the surface of the body plate through a series of processes such as electroplating.
[0031] This LDS antenna uses LDS functional plastic only for the antenna body plate, which solves the problem of existing technologies that require a large amount of LDS to form antenna patterns by laser etching directly on the antenna bracket. The LDS antenna provided by this utility model greatly reduces material costs and material waste.
[0032] In this embodiment, a mounting screw hole 40 is also provided on the other side of the antenna bracket 10. The mounting screw hole is a cylindrical through hole with threads inside, the threads being compatible with a bolt, and the bolt being a round-head bolt. The mounting screw hole is used to connect the LDS antenna to the motherboard.
[0033] As described above, the LDS antenna provided by this utility model connects the antenna support plate and the antenna body plate through grooves and protrusions, which is quick and easy to connect. The use of screw holes and bolts improves the stability of the connection between the antenna support plate and the antenna body plate, making it convenient for installation and disassembly.
[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
