Detailed implementation manners

[0058] To make the purpose, technical solutions and advantages of the present disclosure clearer and more understandable, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs.

[0060] Electronic devices such as mobile phones, tablet computers, and communication watches have become essential technological products in people's lives, learning, and entertainment. With the development of the diverse functions of electronic devices, there is a wide variety of electronic device types and brands, providing consumers with many choices. How to gain the favor of consumers has become an increasingly important issue for electronic device manufacturers.

[0061] Currently, with the development of electronic devices, the integration of electronic devices is getting higher and higher. At the same time, in order to adapt to miniaturization, the gap between electronic components inside the electronic device is getting smaller and smaller, and the layout is getting more and more compact, which also increases the difficulty of antenna layout in electronic devices.

[0062] However, in related technologies, the number of antennas in electronic devices is increasing, and the structure between adjacent antennas is getting more and more compact. Some antennas of electronic devices are realized through frame antennas, but the space of the frame antennas is limited, resulting in difficulty in improving the radiation performance of the frame antennas. For example, electronic devices usually increase the length of the radiation arm of the antenna to improve the radiation performance of the antenna. If the length of the radiation arm of the frame antenna is increased, the radiation performance of other antennas adjacent to the antenna will be reduced, and even an antenna in a certain frequency band cannot be designed on the frame.

[0063] Based on this, it is necessary to provide an electronic device that uses antennas on other structures to enhance the frame antenna so that the frame antenna has good radiation performance.

[0064] To better understand the electronic device of the present disclosure, the following will be described with reference to the accompanying drawings.

[0065] As Figures 1 to 3 shown, in some embodiments, an electronic device 10 is provided, which includes a housing assembly 100, a circuit board 200, and a support member 300. The housing assembly 100 includes a frame 110 and a carrier plate 120. The frame 110 includes a frame antenna 111. At least a part of the carrier plate 120 is disposed inside the frame 110 and is spaced apart from at least a part of the frame antenna 111 to form an antenna gap 101. The circuit board 200 is disposed in the housing assembly 100. The circuit board 200 includes a first antenna 210. The support member 300 is disposed in the housing assembly 100, and the support member 300 is provided with a second antenna 310. Along the thickness direction of the carrier plate 120, the second antenna 310 is spaced apart from the circuit board 200. Among them, the frame antenna 111 is coupled parasitically with the first antenna 210 and the second antenna 310 respectively.

[0066] The electronic device 10 is provided with a frame antenna 111, which is coupled parasitically with a first antenna 210 disposed on a circuit board 200 and a second antenna 310 disposed on a support member 300 respectively, so as to facilitate using the first antenna 210 and the second antenna 310 to enhance the frame antenna 111 and improve the radiation performance of the frame antenna 111. Along the thickness direction of the carrier board 120, the second antenna 310 is spaced from the circuit board 200, so that there is sufficient clearance space between the first antenna 210 and the second antenna 310, and the thickness space of the electronic device 10 can be fully utilized to arrange the antennas, reducing the difficulty of the structural arrangement of the electronic device 10 and enabling the frame antenna 111 of the electronic device 10 to have good radiation performance.

[0067] In some embodiments, when the frame antenna 111 operates, the first antenna 210 and the second antenna 310 are coupled parasitically with the frame antenna 111 and serve as parasitic branches of the frame antenna 111 to enhance the frame antenna 111. When the frame antenna 111 is not in use, the first antenna 210 and the second antenna 310 can be used separately to radiate other radiation frequency bands, so that the electronic device 10 can cover more frequency bands. At the same time, the first antenna 210 and the second antenna 310 can be fully utilized.

[0068] In some embodiments, the frame 110 and the carrier board 120 cooperate to form the middle frame of the electronic device 10.

[0069] In some embodiments, the frame antenna 111 is coupled parasitically with the first antenna 210 and the second antenna 310 respectively and operates in a first radiation frequency band. Furthermore, the radiation performance of the electronic device 10 in the first radiation frequency band is better.

[0070] It should be noted that the first radiation frequency band is one of the MHB frequency band, N79 frequency band, N78 frequency band, N77 frequency band, and WIFI 5G frequency band.

[0071] Among them, the MHB frequency band is 1700 MHz to 2700 MHz, including 3G and 4G frequency bands. In addition, the 5G frequency band of China Mobile is 4800 MHz to 4900 MHz, a total of 100 MHz, and the frequency band number is N79. The 5G frequency band of China Telecom is 3400 MHz to 3500 MHz, a total of 100 MHz, and the frequency band number is N78. The 5G frequency band of China Unicom is 3500 MHz to 3600 MHz, a total of 100 MHz, and the frequency band number is N77. The WIFI 5G frequency band includes CH149.

[0072] Optionally, in some embodiments, the first radiation frequency band includes a first sub-band, and the frame antenna 111 operates in the first sub-band. The first radiation frequency band includes a second sub-band different from the first sub-band, and the first antenna 210 operates in the second sub-band. And / or, the first radiation frequency band includes a third sub-band different from the first sub-band, and the second antenna 310 operates in the third sub-band. In this way, it is convenient to use the first antenna 210 and / or the second antenna 310 to couple parasitically with the frame antenna 111 to achieve cooperation between different sub-bands, so as to increase the bandwidth of the first radiation frequency band and improve the radiation efficiency of the frame antenna 111.

[0073] For example, the first sub-band is the middle frequency band of the first radiation frequency band, and the second sub-band and / or the third sub-band is one of the low frequency band and the high frequency band of the first radiation frequency band.

[0074] In an example, the frequency of the third sub-band is less than the frequency of the first sub-band, and the frequency of the first sub-band is less than the frequency of the second sub-band. In this way, the operating sub-bands of the three antennas are different, which can further increase the bandwidth of the first radiation frequency band and improve the radiation efficiency of the frame antenna 111.

[0075] For example, the first sub-band is the middle frequency band of the first radiation frequency band, the second sub-band is the high frequency band of the first radiation frequency band. The third sub-band is the low frequency band of the first radiation frequency band.

[0076] Optionally, in some embodiments, the first radiation frequency band is the wifi5G frequency band. At this time, the first sub-band is a sub-band of the wifi5G frequency band, and the second sub-band and / or the third sub-band are other sub-bands of the wifi5G frequency band.

[0077] In an example, for example, the first sub-band is the middle frequency band of the wifi5G frequency band, the second sub-band is the high frequency band of the wifi5G frequency band. The third sub-band is the low frequency band of the wifi5G frequency band.

[0078] In some embodiments, the radiation length of the frame antenna 111 is 5 mm to 7 mm. In this way, the radiation arm length of the frame antenna 111 can be flexibly designed according to the actual situation, reducing the antenna design difficulty of the electronic device 10.

[0079] Optionally, the radiation length of the frame antenna 111 is 6 mm to 6.5 mm.

[0080] Optionally, the radiation length of the frame antenna 111 is one of 5 mm, 5.25 mm, 5.5 mm, 5.75 mm, 6 mm, 6.1 mm, 6.2 mm, 6.25 mm, 6.3 mm, 6.4 mm, 6.5 mm, 6.75 mm, 7 mm, etc.

[0081] In some embodiments, the radiation length of the first antenna 210 is 2 mm to 4 mm. In this way, the radiation arm length of the first antenna 210 can be flexibly designed according to the actual situation, as long as it can enhance the border antenna 111, thus reducing the difficulty of antenna design for the electronic device 10.

[0082] Optionally, the radiation length of the first antenna 210 is 2.9 mm to 3.3 mm.

[0083] Optionally, the radiation length of the first antenna 210 is one of 2 mm, 2.25 mm, 2.5 mm, 2.75 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.25 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.75 mm, 4 mm, etc.

[0084] In some embodiments, the radiation length of the second antenna 310 is 3 mm to 5 mm. In this way, the radiation arm length of the second antenna 310 can be flexibly designed according to the actual situation, as long as it can enhance the border antenna 111, thus reducing the difficulty of antenna design for the electronic device 10.

[0085] Optionally, the radiation length of the second antenna 310 is 4 mm to 4.4 mm.

[0086] Optionally, the radiation length of the second antenna 310 is one of 3 mm, 3.25 mm, 3.5 mm, 3.75 mm, 4 mm, 4.1 mm, 4.15 mm, 4.2 mm, 4.25 mm, 4.3 mm, 4.35 mm, 4.4 mm, 4.5 mm, 4.75 mm, 5 mm, etc.

[0087] In an example, the radiation frequency band of the border antenna 111 is the middle frequency band of the wifi5G frequency band. The radiation frequency band of the first antenna 210 is the high frequency band of the wifi5G frequency band. The radiation frequency band of the second antenna 310 is the low frequency band of the wifi5G frequency band. At this time, the radiation length of the border antenna 111 is 6.25 mm, the radiation length of the first antenna 210 is 3.1 mm, and the radiation length of the border antenna 111 is 4.2 mm.

[0088] In some embodiments, the first radiation frequency band includes a fourth sub - frequency band, and at least two of the border antenna 111, the first antenna 210, and the second antenna 310 operate in the fourth sub - frequency band. In this way, when the border antenna 111 operates in the fourth sub - frequency band, by setting the sizes of the first antenna 210 and the second antenna 310, the resonance of the first antenna 210 and / or the second antenna 310 can be made to fall into the fourth sub - frequency band, so that all the power is directed in one place, thereby making the radiation efficiency of the fourth sub - frequency band higher and the radiation farther.

[0089] Further combining the foregoing embodiments, the radiation direction of at least one of the first antenna 210 and the second antenna 310 is different from that of the frame antenna 111, so that the radiation area of the first radiation frequency band is larger, the radiation ability is stronger, and the radiation is farther.

[0090] In one example, the first radiation frequency band is the wifi5G frequency band, and the fourth sub-frequency band is the CH149 frequency band.

[0091] Optionally, in some embodiments, the second antenna 310 includes one of an FPC antenna and an LDS antenna and can be flexibly disposed on the support member 300.

[0092] As Figure 3 shown, in some embodiments, the support member 300 includes an antenna bracket. The antenna bracket includes a first bearing surface 301 disposed close to the circuit board 200 and a second bearing surface 302 disposed opposite to the first bearing surface 301. The second antenna 310 is disposed on at least one of the first bearing surface 301 and the second bearing surface 302. In this way, the second antenna 310 can be flexibly fixed on the antenna bracket, so that the positions of the second antenna 310, the first antenna 210, and the frame antenna 111 are relatively fixed, so as to better enhance the frame antenna 111.

[0093] As Figure 4 shown, in some other embodiments, the support member 300 includes a support column 320 and a support plate 330. One end of the support column 320 is fixed to the circuit board 200, and the other end of the support column 320 is fixed to the support plate 330. The second antenna 310 is disposed on the support plate 330. In this way, through the cooperation of the support column 320 and the support plate 330, the cooperation between the second antenna 310, the first antenna 210, and the frame antenna 111 is closer, so as to better enhance the frame antenna 111.

[0094] As Figure 3 and Figure 4 shown, in some embodiments, the circuit board 200 is provided with a feeding circuit 220, and the frame antenna 111 is conductively fed by the feeding circuit 220. In this way, the impedance can be reduced, and the radiation performance of the frame antenna 111 can be further improved.

[0095] Optionally, in some embodiments, the first antenna 210 and the frame antenna 111 are coupled for feeding. In this way, it is convenient to form a coupled parasitic relationship, and it is convenient to adjust the resonance of the first antenna 210 so as to enhance the frame antenna 111.

[0096] Optionally, in some embodiments, the second antenna 310 and the frame antenna 111 are coupled for feeding. In this way, it is convenient to form a coupled parasitic relationship, and it is convenient to adjust the resonance of the second antenna 310 so as to enhance the frame antenna 111.

[0097] In one example, the first antenna 210 is conductively fed by the feeding circuit 220 and has a first feeding energy. The first antenna 210 is coupled and fed by the frame antenna 111 and has a second feeding energy, and the second feeding energy is greater than the first feeding energy. In this way, the first antenna 210 is conductively fed by the feeding circuit 220, which is convenient for improving the radiation efficiency of the first antenna 210. At the same time, making the second feeding energy greater than the first feeding energy is convenient for coupling parasitically with the frame antenna 111 to enhance the frame antenna 111.

[0098] Referring to Figures 1 to 6 As shown, the length direction of the carrier board 120 is set in the same direction as the length direction of the electronic device 10, which is the X-axis direction. The width direction of the carrier board 120 is set in the same direction as the width direction of the electronic device 10 as the Y-axis direction. The thickness direction of the carrier board 120 is set in the same direction as the thickness direction of the electronic device 10, which is the Z-axis direction.

[0099] As Figure 5 and Figure 6 As shown, in some embodiments, the radiation direction of the first antenna 210 is different from the radiation direction of the frame antenna 111. In this way, the first antenna 210 can be used to supplement the radiation direction of the frame antenna 111, so that the frame antenna 111 and the first antenna 210 form a larger radiation range, enabling the electronic device 10 to have good communication performance in various postures.

[0100] As Figure 5 and Figure 6 As shown, in some embodiments, the radiation direction of the second antenna 310 is different from at least one of the radiation directions of the frame antenna 111 and the first antenna 210. In this way, the second antenna 310 can be used to supplement the radiation direction of the frame antenna 111 or be in the same direction as the frame antenna 111 to enhance the radiation distance of the frame antenna 111.

[0101] As Figure 6 As shown, in some embodiments, the radiation direction of the frame antenna 111 is in the first plane 102, the radiation direction of the first antenna 210 is in the second plane 103, and the radiation direction of the second antenna 310 is in the third plane 104. The first plane 102, the second plane 103, and the third plane 104 are perpendicular to each other in pairs. In this way, the three antennas are mutually coupled, and the radiation directions are complementary, forming a sphere that radiates outward in all directions, forming a stronger, more circular, and larger coverage radiation frequency band. Furthermore, whether the electronic device 10 is used in the vertical screen or the horizontal screen, it has good communication performance.

[0102] As Figure 6 As shown, in one example, the first plane 102 is the xoz plane. The second plane 103 is the xoy plane. The third plane 104 is the yoz plane.

[0103] As Figure 3 and Figure 4 shown, in some embodiments, along the thickness direction of the carrier board 120, the first antenna 210 is disposed above the frame antenna 111, and the second antenna 310 is disposed above the first antenna 210. This facilitates making full use of the thickness space of the electronic device 10 to arrange the antennas, and it is easy to stagger the radiation directions of the first antenna 210 and the second antenna 310 from the radiation direction of the frame antenna 111, so as to increase the bandwidth.

[0104] Optionally, in some embodiments, along the thickness direction of the carrier board, the distance between the first antenna and the frame antenna is L1, and the distance between the second antenna and the first antenna is L2, and L2 = L1. In this way, the three antennas are arranged at equal intervals in the thickness direction of the carrier board, so that the radiation directions of the three antennas in the thickness direction of the carrier board are staggered in sequence, which is beneficial to improving the radiation performance.

[0105] Optionally, in some embodiments, along the thickness direction of the carrier board, the distance between the first antenna and the frame antenna is L1, and L1 = 0.4 mm to 1 mm. In this way, the distance between the first antenna and the frame antenna can be flexibly adjusted in the thickness direction of the carrier board, the arrangement is more regular, and the arrangement difficulty is reduced.
