Description

Technical Field

[0001] This utility model relates to the field of antenna technology, specifically to an antenna structure and electronic device. Background Technology

[0002] Laser-direct structuring (LDS) technology is widely used in fields such as communications, automotive electronics, electromechanical equipment, and medical devices. LDS antennas, for example, utilize this technology to project a laser beam onto a molded three-dimensional plastic device according to the trajectory of a conductive pattern, thereby activating the circuit pattern.

[0003] Currently, most antennas for small mobile devices utilize laser direct forming technology to deposit metal on non-metallic shells. The advantages of this type of antenna are that it is more stable, avoids interference from internal components, and saves more design space, allowing electronic devices to be made thinner.

[0004] However, the aforementioned laser-engraved antennas on the device's casing cannot be fully deployed when an antenna is needed to simultaneously support 2G, 3G, 4G, 5G, and satellite positioning signals, due to the limited space in the casing. Utility Model Content

Detailed Implementation

[0112] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0113] like Figure 1 , Figure 2 As shown, this is a specific implementation of the antenna structure provided in this embodiment, including: a first support 1, a second support 2 and a third support 3, wherein the second support 2 and the third support 3 are respectively arranged at an angle at both ends of the first support 1; specifically, in this embodiment, the second support 2 and the third support 3 are arranged in parallel, and the second support 2 and the third support 3 are respectively perpendicular to the first support 1.

[0114] The first support 1 is provided with a first main antenna 4 and a positioning antenna 5 in sequence. The first main antenna 4 is positioned closer to the second support 2 on the first support 1 than the positioning antenna 5.

[0115] The second bracket 2 is provided with a first diversity antenna 6 and a second main antenna 7 in sequence. The second main antenna 7 is positioned closer to the first bracket 1 on the second bracket 2 than the first diversity antenna 6.

[0116] The third support 3 is equipped with a second diversity antenna 8.

[0117] In this embodiment, the antenna structure, by setting the first main antenna 4, the first diversity antenna 6, the second main antenna 7, the second diversity antenna 8, and the positioning antenna 5 on their respective supports, enables simultaneous support for multiple signals and solves the problem that the antennas cannot be fully deployed on the housing.

[0118] Specifically, the first main antenna 4 can be used to transmit and receive 2G, 3G and 4G signals, and can receive 5G signals, thus serving as the main antenna for 2G, 3G and 4G signals, and simultaneously as a diversity antenna for 5G signals.

[0119] The first diversity antenna 6 can be used to receive 2G, 3G and 4G signals, and can also receive 5G signals, thus serving as a diversity antenna for 2G, 3G and 4G signals, and simultaneously as a diversity antenna for 5G signals.

[0120] The second main antenna 7 can be used to transmit and receive 5G signals, thus serving as the main antenna for 5G signals.

[0121] The second diversity antenna 8 can be used to receive 5G signals, thus serving as a diversity antenna for 5G signals.

[0122] Positioning antenna 5 can be used to receive satellite positioning signals.

[0123] like Figure 3 , Figure 4 As shown, in the antenna structure provided in this embodiment, the positioning antenna 5 has a first radiating arm 10 and a second radiating arm 11. The first radiating arm 10 is closer to the first main antenna 4 on the first support 1 than the second radiating arm 11.

[0124] The first radiating arm 10 includes a first radiating part 9, a second radiating part 14, and a third radiating part 15 connected in sequence. The first radiating part 9 is disposed on the first side 12 of the first support 1, where the first side 12 can be understood as the outer side of the first support 1. The second radiating part 14 is disposed on the front side of the first support 1; it should be noted that the front side can be understood as the upper surface of the first support 1. The third radiating part 15 is disposed on the second side 13 of the first support 1 opposite to the first side 12, where the second side 13 can be understood as the inner side of the first support 1, that is, the inner side of the frame structure formed by the first support 1, the second support 2, and the third support 3.

[0125] By using the above configuration, the first radiating arm 10 is bent into a three-dimensional shape on the first support 1, thereby improving the utilization rate of the first support 1 and reducing the size of the antenna.

[0126] like Figure 3 , Figure 4 As shown, in this embodiment, the second radiating arm 11 includes a fourth radiating part 93, a fifth radiating part 16 and a sixth radiating part 17 connected in sequence. The fourth radiating part 93 is disposed on the first side 12 of the first support 1, the fifth radiating part 16 is disposed on the front of the first support 1, and the sixth radiating part 17 is disposed on the second side 13 of the first support 1.

[0127] By using the above configuration, the second radiating arm 11 is bent into a three-dimensional shape on the first support 1, thereby improving the utilization rate of the first support 1 and reducing the size of the antenna.

[0128] like Figure 3 , Figure 4 As shown, a first bending portion 26 is connected to the first radiating portion 9, and the first bending portion 26 is disposed in the recessed area on the bottom surface of the first bracket 1; this arrangement makes the first bending portion 26 more suitable for electrical connection with the elastic connector.

[0129] like Figure 3 , Figure 4As shown, the second radiating part 14 has multiple extensions connected in sequence. The second radiating part 14 is closer to the first main antenna 4 than the fifth radiating part 16; the third radiating part 15 is closer to the first main antenna 4 than the sixth radiating part 17; the fourth radiating part 93 is connected to the first radiating part 9; the fifth radiating part 16 is disposed on the first bracket 1 at one end away from the first main antenna 4, and the extension direction of the fifth radiating part 16 is perpendicular to the extension direction of the first bracket 1; the sixth radiating part 17 extends toward the third radiating part 15, and there is a gap between the sixth radiating part 17 and the third radiating part 15; a second bent part 27 is connected to the sixth radiating part 17, and the second bent part 27 is disposed in the recessed area on the bottom surface of the first bracket 1; this arrangement makes the second bent part 27 more suitable for electrical connection with the elastic connector. Specifically, the first bent part 26 can be used as a grounding feed point, and the second bent part 27 can be used as a feed input feed point, thereby realizing the electrical connection of the positioning antenna 5. By setting a recessed area on the bottom surface of the first bracket 1, it is easier for the spring-loaded feeder to contact the power supply point, thereby improving installation efficiency and connection stability.

[0130] like Figure 3 , Figure 4 As shown, in this embodiment, the second radiating part 14 has the following components connected in sequence: a first extension 21, a second extension 20, a third extension 22, a fourth extension 23, a fifth extension 24, and a sixth extension 18; one end of the first extension 21 is perpendicularly connected to the first radiating part 9, and the first extension 21 extends toward the second side 13 of the first support 1; the second extension 20 is perpendicularly connected to the first extension 21, and the second extension 20 extends toward a direction away from the second radiating arm 11; the third extension 22 is perpendicularly connected to the second extension 20, and the third extension 22 extends toward the second side 13 of the first support 1; the fourth extension 23 is perpendicularly connected to the extension end of the third extension 22, and the fourth extension 23 extends toward a direction away from the second radiating arm 11; the fifth extension 24 is perpendicularly connected to the extension end of the fourth extension 23, and the fifth extension 24 extends toward the second side 13 of the first support 1; the sixth extension 18 is perpendicularly connected to the fifth extension 24, and the sixth extension 18 extends toward a direction close to the fifth radiating part 16. The above settings enable the positioning antenna 5 to better meet the transmission requirements of the corresponding frequency band.

[0131] like Figure 3 , Figure 4 As shown, the fifth radiating part 16 of the second radiating arm 11, near the fourth radiating part 93, is an arc-shaped segment 25 whose width gradually decreases.

[0132] In the above scheme, any newly added technical feature enables the positioning antenna 5 to better receive the B1 frequency signal provided by the BeiDou satellite navigation system, improves the reception capability of the 1561MHz band of the B1 frequency signal, and makes the received BeiDou satellite signal more identifiable.

[0133] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the first main antenna 4 has a third radiating arm 29 and a fourth radiating arm 30, and the fourth radiating arm 30 is closer to the positioning antenna 5 on the first bracket 1 than the third radiating arm 29.
