[0024] With the popularization of smart devices, smart rings have gradually become well-known to people. Smart rings are usually connected to terminals such as mobile phones via Bluetooth or WiFi to transmit signals. For example, data is transmitted back through the smart ring to operate a remote-controlled drone or control a car, etc. With the rise of smart rings, the antenna design on smart rings has also become a new problem.

[0025] Please refer to Figure 1 and Figure 2 , in some embodiments of this disclosure, a ring is proposed, which includes a first ring segment 1, a second ring segment 2, and a connecting portion 3. The first ring segment includes a conductive wall body and a circuit module. The conductive wall body covers the outside of the circuit module and is electrically connected to the circuit module. The circuit module includes, for example, a power supply, a baseband, a chip, and radio frequency components. The conductive wall body is prepared by using, for example, a metal material; the second ring segment 2 is arranged at a circumferential interval from the first ring segment 1, and the second ring segment 2 is conductive and electrically connected to the circuit module; the connecting portion 3 is respectively connected to the first ring segment 1 and the second ring segment 2, and can be connected by physical connection means such as welding or bonding; wherein, the circuit module, the conductive wall body, and the second ring segment 2 form an antenna circuit. In some embodiments of this disclosure, the circuit module, the conductive wall body, and the second ring segment 2 form an antenna circuit, so as to be able to transmit or receive antenna signals. In some embodiments, the antenna circuit can be, for example, a Bluetooth antenna circuit or a 2.4G antenna circuit, or an antenna circuit of other frequency bands, and this is not limited.

[0026] In some embodiments, the conductive wall can mainly serve as the reference ground in the antenna and can be electrically connected to the ground terminal of the circuit module. The second ring segment 2 electrically connected to the circuit module can serve as the radiation component in the antenna. The second ring segment 2 can be electrically connected to the feeding terminal of the circuit module. By cooperating with the circuit module, the second ring segment 2 and the conductive wall, the function of the antenna is realized. Therefore, no additional material is required, and the function of the antenna is directly realized by using the finger ring itself. Moreover, the circuit module is located inside the conductive wall, and the circuit module does not occupy the antenna radiation clearance. Since the conductive wall covers the circuit module, on the one hand, the conductive wall can protect the circuit module from being damaged. On the other hand, the conductive wall can shield the influence of the circuit module on the radio frequency signal. The radiation current of the antenna is located on the second ring segment, while the signal of the circuit module is inside the conductive wall, and the internal and external signals are in a state of mutual isolation, thus preventing the internal and external signals from interfering with each other. The finger ring provided in this embodiment not only prevents the internal and external signals from interfering, but also makes full use of the second ring segment 2 and the conductive wall, saving the space for additionally arranging the antenna. In addition, the first ring segment 1 and the second ring segment 2 can cooperate to form a circular structure. While realizing the function of the antenna, the finger ring itself also ensures the aesthetic appearance.

[0027] In some embodiments of the present disclosure, the second ring segment 2 and the conductive wall may not be electrically connected. At this time, the circuit module, the conductive wall and the second ring segment form a Monopole antenna. In some other embodiments of the present disclosure, the connecting portion 3 is made of a conductive material and is electrically connected to the conductive wall and the second ring segment 2 respectively. At this time, the conductive wall and the second ring segment 2 are electrically connected, and the circuit module, the conductive wall, the connecting portion 3 and the second ring segment can form an IFA antenna (Inverted F Antenna). At this time, the connecting portion 3 can be equivalent to an inductor component with respect to high-frequency electromagnetic waves.

[0028] In some embodiments of the present disclosure, the conductive wall, the connecting portion 3 and the second ring segment 2 are integrally formed. In this embodiment, through the integrated design, the whole finger ring has a complete mechanical structure, high structural strength, can well support the first ring segment 1 and the second ring segment 2, and protect each component in the finger ring. At the same time, the aesthetic appearance of the whole finger ring can be improved. In some embodiments of the present disclosure, the conductive wall, the connecting portion 3 and the second ring segment 2 are made of a metal material, for example. Using a metal material can ensure that the finger ring has a strong connection strength, and the metal material has good antenna performance and beautiful texture. In some embodiments, the metal material can be silver, for example. By using silver metal, it can not only have good aesthetic appearance, but also reduce the resistance to improve the antenna power.

[0029] In some embodiments of the present disclosure, the circuit module is electrically connected to the second ring segment 2 through a conductive elastic sheet or a conductive screw. In some embodiments, the circuit module is located inside the conductive wall body. At this time, an electrical connection can be established with the conductive module located inside the conductive wall body through a conductive elastic sheet or a conductive screw. Small holes can be opened on the conductive wall body, and the conductive elastic sheet or the conductive screw electrically connected to the circuit module passes through the small holes and is connected to the second ring segment 2. After the second ring segment 2 is electrically connected to the circuit module, it can serve as a radiator of the antenna.

[0030] In some embodiments of the present disclosure, please continue to refer to Figure 1 and Figure 2 , the connecting portion 3 is located inside the ring formed by the first ring segment 1 and the second ring segment 2. In some embodiments, the first ring segment 1 and the second ring segment 2 are located on the same ring. Since the connecting portion 3 is located inside the ring, the radiation space outside the finger ring is not blocked, thereby reducing the influence of the connecting portion 3 on the radiation performance.

[0031] In some embodiments of the present disclosure, the connecting portion 3 includes a first sub-portion 31 and a second sub-portion 32; both ends of the first sub-portion 31 are respectively connected to the inner wall of the first ring segment 1; one end of the second sub-portion 32 is connected to the first sub-portion 31, and the other end of the second sub-portion 32 is connected to the inner wall of the second ring segment 2. As Figure 1 shown, both ends of the first sub-portion 31 can be connected to both ends of the opening of the first ring segment 1, so that the first ring segment 1 and the first sub-portion 31 form a ring to enhance the mechanical strength of the finger ring. The second sub-portion 32 is respectively connected to the first sub-portion 31 and the second ring segment 2 to support the second ring segment 2.

[0032] In some embodiments of the present disclosure, the central angle corresponding to the first ring segment 1 is greater than 180°, and the central angle corresponding to the second ring segment 2 is less than 180 degrees. In some embodiments, the length of the first ring segment is greater than half of the circle it is on, and the length of the second ring segment is less than half of the circle it is on. The first ring segment 1 and the second ring segment 2 form the main structure of the finger ring. The conductive wall body of the first ring segment 1 serves as the reference ground of the antenna, so a larger length is required.

[0033] In some embodiments of the present disclosure, as Figure 3 and Figure 4 shown, the finger ring further includes: a filling portion 5. The filling portion 5 is made of a non-metallic material, and the filling portion 5 is filled between the first ring segment 1 and the second ring segment 2. As Figure 3 and Figure 4As shown, the wall surface of the filling portion 5 close to the outer side of the finger ring, the outer wall surface of the first ring segment 1, and the outer wall surface of the second ring segment 2 can form a smooth toroidal surface. By providing a filling portion made of a non-metallic material between the first ring segment 1 and the second ring segment 2, the appearance of the finger ring can be improved, making the appearance of the finger ring present as a complete ring, and at the same time increasing the connection strength between the first ring segment 1 and the second ring segment 2.

[0034] In some embodiments of the present disclosure, please refer to Figure 2 , the second ring segment 2 is electrically connected to the circuit module through a conductive branch 4. The conductive branch 4 can be connected to the inner wall of the second ring segment 2. The circuit module is electrically connected to the conductive branch 4 through a conductive screw or a spring piece passing through the conductive wall body; the conductive branch 4 is located inside the filling portion. In some embodiments, since the conductive branch is located inside the filling portion 5, on the one hand, the appearance is improved and the conductive branch is prevented from being seen from the outside. On the other hand, the electromagnetic interference of the current on the conductive branch to the second ring segment 2 as an antenna radiator can be reduced.

[0035] In some embodiments, as Figure 3 and Figure 4 shown, the filling portion 5 also fills between the second ring segment 2 and the connecting portion 3, so as to further strengthen the connection strength between the second ring segment 2 and the connecting portion 3. The filling portion 5 can adopt an organic binder.

[0036] In order to better illustrate the finger ring proposed in the embodiments of the present disclosure, a specific embodiment is proposed below. Please refer to Figures 1 to 4, the finger ring proposed in this embodiment includes a first ring segment 1, a connecting portion 3, a second ring segment 2, and a filling portion 5. The first ring segment 1 includes a conductive wall body and a circuit module. The circuit module is encapsulated inside the conductive wall body, and the ground terminal of the circuit module is electrically connected to the conductive wall body. The first ring segment 1 is a section of a circular ring, and the second ring segment 2 is a section of a circular ring. The first ring segment 1 and the second ring segment 2 are located on the same ring and are spaced apart. The inner wall surface of the second ring segment 2 is connected to the first ring segment through a connecting portion 3 made of metal. There is a conductive branch 4 serving as a feed point terminal on the inner wall surface of the second ring segment 2, and the conductive branch 4 is electrically connected to the feed terminal of the circuit module. The conductive wall body, the connecting portion 3, and the second ring segment 2 are all made of metal materials and are integrally connected. The circuit module is electrically connected to the conductive branch 4 through a metal shrapnel or a metal screw, etc. In this way, the circuit module, the conductive wall body, and the second ring segment 2 form an antenna circuit. The conductive wall body mainly serves as a reference ground, and the second ring segment 2 mainly serves as a radiator. The filling portion 5 fills the space between the first ring segment 1 and the second ring segment 2, and also fills the space between the second ring segment 2 and the connecting portion 3. The finger ring antenna proposed in some embodiments of the present disclosure can, for example, operate in the working frequency bands (2.4 GHz - 2.5 GHz) of a Bluetooth antenna and a WiFi 2.4G antenna, and the working frequency band can also be adjusted as needed. The finger ring proposed in this embodiment fully utilizes the finger ring as an antenna. The finger ring itself is the antenna, no additional materials are required, the circuit module does not occupy the antenna radiation clearance, and the antenna performance is good. The connecting portion 3 made of metal is hidden inside the non-metallic filling portion 5, and the appearance is neat and generous. The outer side of the circuit module of the finger ring is encapsulated with a conductive wall body made of metal, which completely shields the influence of the circuit module on the antenna. The radiation current of the antenna is on the conductive wall body, and the circuit module is inside the conductive wall body. Therefore, the internal and external signals are in a separated state. The structure of the finger ring and the antenna in this embodiment are integrally designed, taking into account both the structural strength and the antenna radiation performance. The schematic diagram of the antenna radiation current of the finger ring proposed in this embodiment is as Figure 5 shown, and the resonance schematic diagram of the finger ring antenna is as Figure 6 shown. The antenna in this embodiment operates in the working frequency band (2.4 GHz - 2.5 GHz) of a WiFi 2.4G antenna. The radius of the second ring segment is 12 mm. From Figure 6 , it can be seen that the return values between point 1 and point 2 are all lower than -6 dB, which indicates that the antenna radiation performance of the finger ring is excellent. Thus, it can be seen that the finger ring proposed in this embodiment has good performance in the frequency band from 2.4 GHz to 2.5 GHz and meets the usage requirements.
