In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The following describes the embodiments of the present invention in conjunction with the accompanying drawings.

[0039] Please also read Figure 1 and Figure 2The embodiment of the present disclosure provides a nameplate antenna 10, which is arranged on a substrate 20. Specifically, the substrate 20 is a flexible circuit board. The nameplate antenna 10 includes a connector 11, a nameplate body 12 and a second radiator 13. The middle part of the connector 11 is provided with an embedding groove 111, and the connector 11 is made of an insulating material and used to form a clearance area. The nameplate body 12 is embedded in the embedding groove 111, and the nameplate body 12 is made of a conductive material and used to form a first radiator. The second radiator 13 is arranged between the substrate 20 and the nameplate body 12, and the second radiator 13 is made of a conductive material and electrically connected to the nameplate body 12. Exemplarily, the material of the connector 11 can be plastic, the material of the first radiator can be an aluminum-magnesium alloy, and the material of the second radiator 13 can be copper.

[0040] In the above-mentioned nameplate antenna 10, the nameplate body 12 is made of a conductive material to form a first radiator, and the second radiator 13 arranged on the substrate 20 is attached to one side of the nameplate body 12, and the first radiator and the second radiator 13 are electrically coupled to better radiate electromagnetic wave signals. Then, the nameplate body 12 is embedded in the embedding groove 111 on the connector 11, and a clearance area is formed by the insulating material at the peripheral position of the connector 11 to reduce the interference of the metal shell 30 with the antenna radio frequency signal, thereby ensuring the radio frequency performance of the nameplate antenna 10; in this way, by combining the antenna with the nameplate of the electronic device and forming a clearance area by the connector 11 made of insulating material, the nameplate antenna 10 in the present application does not need to design a more complex antenna structure, and can ensure good radio frequency performance without affecting the aesthetics of the electronic device, so that the nameplate antenna 10 has good radio frequency performance on the basis of simple structure and no impact on aesthetics.

[0041] In this embodiment, the thickness of the nameplate body 12 is 0.8 mm, the length of the nameplate body 12 is 35 mm-45 mm, and the width of the nameplate body 12 is 15-20 mm.

[0042] Furthermore, the thickness of the substrate 20 is 0.2 mm, and the length and width of the substrate 20 are consistent with the length and width of the nameplate body 12 .

[0043] Furthermore, the length and width of the second radiator 13 are consistent with the length and width of the nameplate body 12 , and the second radiator 13 has a length direction and a width direction.

[0044] Furthermore, the nameplate body 12 includes a main body portion 121 and a pattern portion 122 . The pattern portion 122 is connected to a side of the main body portion 121 away from the second radiator 13 , and both the main body portion 121 and the pattern portion 122 are made of conductive material.

[0045] See also Figure 3In some embodiments, a first slot 131 is provided on the second radiator 13, and the first slot 131 is used to expand the frequency band of the second radiator 13; further, the first slot 131 includes a central slot 1311 and a plurality of L-shaped slots 1312, the central slot 1311 is provided on the second radiator 13, and the plurality of L-shaped slots 1312 are provided on the second radiator 13, and the plurality of L-shaped slots 1312 are circumferentially spaced about the center line of the central slot 1311 as the axis, and each L-shaped slot 1312 is connected to the central slot 1311.

[0046] It can be understood that the first slot 131 can achieve the function of creating a very small antenna. The direction of current flow is changed by the structure of the first slot 131, and the direction of current flow is changed from a straight line to a curve, thereby extending the flow distance of the current. By increasing the flow distance of the current, the bandwidth or the number of operating frequency bands can be increased without expanding the size of the antenna.

[0047] See also Figure 4 Furthermore, the first slot 131 is roughly in a dart-shaped structure, and the central slot 1311 is in a regular hexagonal structure. The number of L-shaped slots 1312 is three, and the three L-shaped slots 1312 are arranged at uniform circumferential intervals with the center line of the central slot 1311 as the axis, so that the angle between any group of two adjacent L-shaped slots 1312 is 120°, and each L-shaped slot 1312 is connected to the central slot 1311.

[0048] Specifically, the distance between the two opposite sides of the center groove 1311 is A, and A is 0.73 mm, the length of the L-shaped groove 1312 is B, and B is 1.36 mm, the L-shaped groove 1312 includes a first bending portion 13121 and a second bending portion 13122 that are connected to each other, and the angle between the first bending portion 13121 and the second bending portion 13122 is 90°, the first bending portion 13121 is close to and connected to the center groove 1311, and the second bending portion 13122 is far away from the center groove 1311, wherein the width of the first bending portion 13121 is C, and C is 0.2 mm, and the width of the second bending portion 13122 is D, and D is 0.27 mm.

[0049] Furthermore, there are two groups of first slots 131, which are arranged at opposite ends of the second radiator 13 in the length direction, and each group of first slots 131 has multiple first slots 131, and the multiple first slots 131 in each group are arranged at intervals along the width direction of the second radiator 13.

[0050] See also Figure 3In some embodiments, a second slot 132 is further provided on the second radiator 13 to improve the radiation intensity of the second radiator 13. The second slot 132 includes two triangular slots 1321 of exactly the same shape and size. The two triangular slots 1321 are symmetrically arranged with the center line of the width direction of the second radiator 13 as the symmetry line, and one end angle of each triangular slot 1321 faces the center line of the width direction of the second radiator 13.

[0051] Thus, by designing the second slot 132 on the second radiator 13 , the receiving and radiating areas of the antenna are increased, thereby ensuring that the nameplate antenna 10 can still obtain stable radio frequency performance in the operating environment of the metal or plastic housing 30 .

[0052] See also Figure 3 Specifically, the width of the second radiator 13 is 19 mm, each triangular groove 1321 is a right triangle, and each triangle has a first right angle side, a second right angle side and a hypotenuse, the length of the first right angle side is and extends along the width direction of the second radiator 13, and E is 8 mm, the length of the second right angle side is F and extends along the length of the second radiator 13, and F is 5 mm, and the distance between each triangular groove 1321 and an edge line in the width direction of the second radiator 13 is G, and G is 5.4 mm.

[0053] The second slot 132 is designed using the overlapping principle of two half dipoles. For example, two half dipoles made of two triangular plates of exactly the same size and shape are connected by a power line, and the triangular plates are also conductors. In this case, the radiation and receiving capabilities of the half dipole can be increased. In this way, when two triangular slots 1321 are designed on the second radiator 13, based on the overlapping principle, the radiation and receiving capabilities of the second radiator 13 can be increased, thereby improving the receiving and radiation surface of the nameplate antenna 10.

[0054] Furthermore, the number of the second slots 132 is two groups, and the two groups of second slots 132 are disposed at two opposite ends in the length direction of the second radiator 13 .

[0055] See also Figure 3 In some embodiments, the second radiator 13 is further provided with two strip holes 133, which are arranged at intervals along the length direction of the second radiator 13 and extend along the width direction of the second radiator 13; one end of each strip hole 133 forms an opening structure, and the other end of each strip hole 133 extends to the middle of the second radiator 13, and the feeding point on the second radiator 13 is arranged between the two strip holes 133. Specifically, the length of each strip hole 133 is 8 mm.

[0056] In this way, the two strip holes 133 form a waveguide groove, and the coplanar waveguide principle is used to design the waveguide groove near the antenna feeding point, so that the antenna can produce a strong coupling effect and maintain consistent impedance matching on different materials, further ensuring the stability and adaptability of the antenna in different environments, ensuring the stability of the RF performance, and ensuring the electromagnetic coupling effect under the outer shell 30 of each material.

[0057] See also Figure 5 In some embodiments, the vertical distance between the inner edge line and the outer edge line of the connector 11 is the clearance distance, the clearance distance is H, and H is greater than 5 mm; when the clearance distance is less than 5 mm, the metal casing 30 of the electronic device will significantly weaken the RF performance of the nameplate antenna 10, and when the clearance distance is greater than 5 mm, it can ensure that the nameplate antenna 10 has good RF performance.

[0058] In some embodiments, the second radiator 13 is bonded to the nameplate body 12 by conductive adhesive, so that the second radiator 13 and the nameplate body 12 can be attached and effectively connected, so as to ensure that the second radiator 13 and the nameplate body 12 can stably transmit signals under different material environments of the shell 30. Specifically, the conductive adhesive is a double-sided conductive adhesive.

[0059] See also Figure 5 The disclosed embodiment also provides an electronic device, which includes the above-mentioned nameplate antenna 10 and a housing 30, wherein the housing 30 is provided with a mounting hole, the mounting hole being connected to the inside and outside of the housing 30, and the nameplate antenna 10 is installed in the mounting hole. For example, the electronic device can be a laptop computer, and accordingly, the nameplate antenna 10 is arranged on the housing 30 of the laptop computer. Specifically, the nameplate antenna 10 is arranged on the C part.

[0060] Furthermore, the electronic device may also be a mobile phone or smart wearable device, which are products with high requirements on appearance design.

[0061] In some embodiments, when the housing 30 of the electronic device is made of metal material, the nameplate antenna 10 can effectively avoid the shielding effect of the metal, thereby ensuring the radio frequency performance of the nameplate antenna 10; when the housing 30 of the electronic device is made of plastic material, the signal transmission efficiency can be maximized, the penetration of the antenna signal can be greatly increased, and the gain of the nameplate antenna 10 is improved, thereby improving the radio frequency performance of the nameplate antenna 10.

[0062] See also Figure 6 , Figure 7 and Figure 8 ,in, Figure 6 This is the field distribution diagram of the nameplate antenna 10 during the simulation test in the 2.45GHZ frequency band. Figure 7This is the field distribution diagram of the nameplate antenna 10 during the simulation test in the 5.5GHZ frequency band. Figure 8 It is the field distribution diagram of the nameplate antenna 10 during the simulation test in the 6.5GHZ frequency band. In the metal shell environment, when simulating the signal test of different frequency bands, the field pattern of the nameplate antenna 10 is complete and there is no null angle. That is, the nameplate antenna 10 can effectively radiate signals in all directions without blind spots, and the radiation intensity is uniform and stable, meeting the design requirements.

[0063] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
