Description

Technical Field

[0001] This utility model relates to the field of laser-engraved antenna technology, specifically a small-sized multi-band 4G laser-engraved antenna. Background Technology

[0002] As is widely known, a laser-etched antenna is an antenna manufactured using laser direct forming technology. This involves activating circuit patterns on the surface of a three-dimensional plastic device with a laser, followed by chemical plating to form a metal antenna.

[0003] For example, the utility model patent with application publication number CN214336918U, application publication date of October 1, 2021, and titled "A Laser-Engraved Antenna Structure", has the following specific structure: an antenna housing; laser-engraved antenna lines arranged on the surface of the antenna housing; a rotating connecting part hinged to one end of the antenna housing; and a coaxial feed line, one end of which passes through the rotating connecting part and connects to the feed point of the laser-engraved antenna lines.

[0004] The shortcoming of the existing technology is that by longitudinally arranging the laser-engraved antenna lines on the surface of the housing between the first and second housings to form the laser-engraved antenna, the overall size of the laser-engraved antenna is relatively long, which makes it difficult to meet the current requirements for miniaturization and small size of laser-engraved antennas.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figure 1 and Figure 2 As shown, this example improves upon the original laser-etched antenna by dividing the circuit on the substrate 1 into a main radiating circuit 21 and a secondary radiating circuit 22. The main radiating circuit 21 is L-shaped and extends to the outer surface of the substrate 1, thereby reducing the longitudinal length of the circuit on the substrate 1 and shortening the length of the laser-etched antenna, thus meeting the requirements for miniaturization and small size of the laser-etched antenna.

[0028] Specifically, the electrical connection method between the main radiating line 21 and the secondary radiating line 22 and the feed point 23 is common technical knowledge to those skilled in the art and will not be elaborated here.

[0029] In the above technical solution, the circuits on the substrate 1 are divided into main radiating circuits 21 and secondary radiating circuits 22, and the main radiating circuit 21 is L-shaped to extend to the outer surface of the substrate 1, thereby reducing the longitudinal length of the circuits on the substrate 1, shortening the size of the laser-engraved antenna, and realizing the miniaturization and small size requirements of the laser-engraved antenna.

[0030] Example 2

[0031] Combination Figure 2 , Figure 3 and Figure 4 As shown, this example provides an additional shielding protection structure for the feed point 23 based on Embodiment 1. That is, the shield 3 is inserted into the substrate 1 to shield and protect the feed point 23, thereby preventing the feed point 23 from being accidentally worn away or damaged by collision during the transport of the laser-engraved antenna. Secondly, it can also reduce the oxidation rate of the feed point 23 and improve the protection of the feed point 23.

[0032] Specifically, such as Figure 3As shown, a limiting part 32 is integrally formed on the shielding cover 3. When the shielding cover 3 is inserted into the inner side of the fixing base 1 to shield and protect the power supply point 23, the limiting part 32 can abut against the outer side of the base 1. Thus, the limiting part 32 can improve the fixing stability of the shielding cover 3 on the base 1. Furthermore, the limiting part 32 can also improve the sealing performance of the shielding cover 3 to improve the protection of the power supply point 23.

[0033] Example 3

[0034] Combination Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further improves the base 1 and the shield 3 based on embodiment 2. The shield 3 is inserted into the mounting groove 12 of the rib plate 11 through the connecting part 31, thereby completing the installation and fixation of the shield 3 on the base 1, which facilitates the installation of the shield 3 during the transportation of the laser-engraved antenna.

[0035] Specifically, the connecting part 31 and the shield 3 are integrally formed, such as Figure 4 As shown, protrusions are provided on both sides of the end of the connecting part 31 so that the connecting part 31 can be snapped onto the rib part 11.

[0036] Example 4

[0037] Combination Figure 4 As shown, this embodiment further improves the shield 3 based on embodiment 3 by pre-embedding several metal wires 4 inside the shield 3, thereby improving the shield stability of the shield 3 above the power supply point 23 and further improving the protection of the power supply point 23.

[0038] Specifically, several metal wires 4 are arranged parallel to one end of the long side of the substrate 1.

[0039] Example 5

[0040] Combination Figure 4As shown, this embodiment provides a reinforcement structure for the shielding cover 3 based on embodiment four, namely, a connecting rope 5. When the shielding cover 3 is inserted into the base 1, the connecting rope 5 passes through several metal wires 4. The limiting part 32 of the connecting rope 5 can be manually pulled, causing the connecting rope 5 to pull the shielding cover 3 closer to the feed point 23. At this time, several metal wires 4 are stretched and deformed, and the shielding cover 3 forces some of the gas inside to the outside of the shielding cover 3 and the base 1. Furthermore, due to their own elastic potential energy, the metal wires 4 exert pressure on the shielding cover 3 to deform away from the feed point 23, thereby creating a negative pressure space within the shielding cover 3, further improving the stability of the shielding cover 3 on the base 1 and the protection of the feed point 23. Secondly, when it is necessary to remove the shielding cover 3, the limiting part 32 of the connecting rope 5 can be pulled directly to deform the connecting part 31 and pass through the mounting groove 12, thereby quickly removing the shielding cover 3 from the base 1.

[0041] Specifically, such as Figure 4 As shown, the lower end of the connecting rope 5 is the first end, and the upper end is the second end. The limiting plate part 51 and the deformation part 52 are glued to the connecting rope 5.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
