The following describes in detail the schemes provided in the embodiments of the present application with reference to the accompanying drawings.

With the popularity of intelligent devices, intelligent finger rings are gradually known, and the intelligent finger rings are usually connected with terminals such as mobile phones through bluetooth or WiFi to transmit signals, so that antenna designs on the finger rings also become new hot spot problems.

In some embodiments of the present disclosure, a ring is presented, as shown in fig. 1, the ring 1 in some embodiments of the present disclosure includes a ring body 10. In some embodiments, the finger ring body 10 is made of a conductive material and is the radiating main portion of the antenna. In some embodiments, the ring body 10 has a slit 11 and a notch 12.

In some embodiments, the finger ring 1 may further include a circuit assembly (not shown), a first end of the circuit assembly being electrically connected to the first end of the finger ring body 10, a second end of the circuit assembly being electrically connected to the second end of the finger ring body 10, the first and second ends of the finger ring body 10 being located on opposite sides of the slit 11. In some embodiments, one of the first and second ends of the circuit assembly is a feed end and the other of the first and second ends of the circuit assembly is a ground end.

In some embodiments, the ring 1 may further include first and

second metal branches

13 and 14, respectively, the first and

second metal branches

13 and 14 filling portions of the recess 12 of the ring body 10 and each being electrically connected with the ring body 10. In some embodiments, the finger ring body 10, the first metal branch 13, and the second metal branch 14 may constitute an antenna circuit of the finger ring. For example, the feeding end of the circuit assembly may feed the finger ring body 10 on one side of the slot 11, and the current may flow through the finger ring body 10 through the first metal branch 13, then through the finger ring body 10 with the notch 12, then through the second metal branch 14, and finally back through the finger ring body 10 to the ground end of the circuit assembly, forming a closed loop. In some embodiments, some current may pass through only one of the first metal branch 13 and the second metal branch 14. In some embodiments, some current may flow from one end of the finger ring body 10 to the other end of the finger ring body 10 after flowing out of the feed end of the circuit assembly without passing through the first metal branch 13 and the second metal branch 14, forming a closed loop.

In some embodiments, phase diagrams of the current distribution of the finger ring at 2.45GHz are shown in fig. 5-8. Therefore, the finger ring 1 disclosed by the invention is tuned through the first metal branch 13 and the second metal branch 14, so that the path of current in the finger ring is lengthened on one hand, and the miniaturization of the finger ring antenna is realized. The resonant frequency can be expressed by the following formula:

wherein L can be represented as the effective radiation length of the ring, W can be represented as the effective radiation width of the ring, c is the speed of light, ε _r The dielectric constant of the filled dielectric is shown. By increasing the effective radiating length and the effective radiating width of the finger ring, the resonant frequency of the finger ring antenna can be reduced, and coverage of a low frequency band (e.g., 2.4G bluetooth band) can be achieved on a finger ring of small volume.

On the other hand, the finger ring body 10, the first metal branch 13 and the second metal branch 14 of the present disclosure function as a radiating antenna of the finger ring, do not require additional antenna parts, and can achieve dual band coverage.

In some embodiments, as shown in fig. 2, the finger ring 1 may further include a first dielectric 15 filling the gap 11, with the circuit components embedded within the first dielectric 15. The circuit component is embedded in the first dielectric body 15, and the first dielectric body 15 can protect the circuit component from being damaged; on the other hand, the space of the finger ring is fully utilized, and the miniaturization design of the finger ring is promoted.

In some embodiments, as shown in fig. 2, the finger ring 1 may further include a second dielectric 16, the second dielectric 16 filling the remainder of the recess 12. By filling the second dielectric 16 in the gap 11, the overall aesthetics and smoothness of the finger ring 1 are improved.

In some embodiments, as shown in FIG. 1, the second dielectric 16 is T-shaped. In some embodiments, the first dielectric 15 is symmetrically disposed with respect to the leg of the T of the second dielectric 16. That is, the first dielectric 15 faces the leg of the T-shape of the second dielectric 16. In some embodiments, the leg of the T of the second dielectric 16 is near the edge of the finger ring 1 in the width direction (up-down direction in fig. 1). That is, a lateral portion of the T-shape is away from the widthwise edge of the finger ring 1, and it is understood that the widthwise direction of the finger ring refers to the extending direction of the finger when the finger ring is worn on the finger. In this way, the first metal branch 13 and the second metal branch 14 are separated from the finger ring body 10 in the width direction of the finger ring 1, when the current from the feed end of the circuit assembly flows to the first metal branch 13 through the finger ring body 10, then flows to the second metal branch 14 through the finger ring body 10, and finally flows back to the ground end of the circuit assembly through the finger ring body 10, the configuration can increase the length of the current path, can realize a lower frequency band on the finger ring antenna, and is also beneficial to miniaturization design of the finger ring.

In some embodiments, the outer edges of the first metal dendrites 13 and the second metal dendrites 14 are flush with the outer edge of the ring body 10 in the width direction of the ring 1. In this way, not only is the aesthetic design of the finger ring 1 facilitated, but the current path length through the first metal branch 13 and the second metal branch 14 can be maximized.

In some embodiments, the ring body 10, the first metal knuckle 13, and the second metal knuckle 14 are integrally formed. By integrally molding the ring body 10, the first metal branch 13 and the second metal branch 14, not only is the aesthetic degree of the ring enhanced, but also the strength of the ring is enhanced.

It should be appreciated that the second dielectric 16 may be positioned at any suitable location for tuning the resonant frequency. In addition, the dimensions and positions of the first metal stub 13, the second metal stub 14, and the second dielectric 16 may also be adjusted accordingly to obtain corresponding resonant frequencies, as shown in fig. 3-4.

In some embodiments, the inner surface of the first dielectric 15 forms a smooth surface with the inner surface of the finger ring body 10 and the outer surface of the first dielectric 15 forms a smooth surface with the outer surface of the finger ring body 10. In some embodiments, the inner surfaces of the first and

second metal knuckles

13, 14 form a smooth surface with the inner surface of the ring body 10, and the outer surfaces of the first and

second metal knuckles

13, 14 form a smooth surface with the outer surface of the ring body 10. In some embodiments, the inner surface of the second dielectric 16 forms a smooth surface with the inner surface of the finger ring body 10 and the outer surface of the second dielectric 16 forms a smooth surface with the outer surface of the finger ring body 10. Thus, the wearing comfort of the finger ring and the beautiful appearance of the finger ring can be improved.

In some embodiments, the lengths of the first metal dendrite 13 and the second metal dendrite 14 in the circumferential direction of the ring 1 are the same or different. The lengths of the first metal branch 13 and the second metal branch 14 in the circumferential direction of the finger ring 1 can be used for adjusting the lengths of the two current paths, so that the resonant frequency band of the antenna can be adjusted, and better radiation performance of the corresponding frequency band can be obtained.

In some embodiments, the ring body 10, the first metal stem 13, and the second metal stem 14 each independently comprise one or more of gold, silver, platinum, and an alloy. These materials can improve the aesthetics and quality of the ring. In some embodiments, the first dielectric 15 and the second dielectric 16 each independently include one or more of FR4 resin, cyanate resin, and polyurethane resin. These resin materials have a high dielectric constant, for example, a dielectric constant of 4.3 for FR4 resin, and can further promote miniaturization of the finger loop antenna. It should be understood that the above materials are exemplary only and are not intended to limit the present disclosure.

The finger ring is completely utilized as the antenna, and the finger ring is the antenna without additional materials. The schematic diagrams of the radiation current of the antenna of the finger ring proposed in the embodiment of the present disclosure are shown in fig. 5 to 8, and the resonance schematic diagram of the finger ring antenna is shown in fig. 9, and it can be seen from the figure that the finger ring proposed in the embodiment covers 2.2GHz to 2.7GHz and 3.4GHz to 4.2GHz dual bands, and each band has better broadband characteristics and radiation characteristics. Because the size of the finger ring is relatively small, the traditional mode is difficult to realize the coverage of a 2.4GHz frequency band on the size, and the introduction of the tuning metal branch knot leads to the lengthening of the path of the current in the intelligent finger ring, thereby realizing the miniaturization of the antenna; the second dielectric is designed to fit the tuning metal stub in order to enable a further reduction in the size of the antenna by loading the dielectric in the vicinity of the metal.
