[0038] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in the specification are for illustrative purposes only.

[0039] Unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0040] The antenna, as a transceiver device that can receive and transmit electromagnetic waves, is widely used in communication devices to enable the communication device to communicate with the outside world. With the development and application of signals of different frequency bands, antennas limited to specific frequency bands have been difficult to meet the needs of the use of multiple frequency bands in communication devices. Therefore, antennas of different frequency bands are usually placed in groups in communication devices, but the built-in method occupies limited space in the communication device with the antenna group, thereby restricting the development of high integration and miniaturization of the communication device.

[0041] In order to reduce the influence of the antenna group on the limited space in the communication device, the utility model provides a structure which uses the frame of the communication device as the antenna group.

[0042] Please refer to Figures 1 to 4 , the antenna group 1000 includes the conductive frame body 1 and the insulating section 2, wherein the conductive frame body 1 includes a plurality of conductor parts 11, the plurality of conductor parts 11 are annularly arranged to form a frame for mounting the main body B of the communication device 2000, two adjacent conductor parts 11 are arranged with a gap to form a gap 12, and the plurality of conductor parts 11 constitute a plurality of first communication antennas; the conductor part 11 is provided with a grounding end 111 and a communication end 112, which are used for connecting the main body B; the insulating section 2 is filled in the gap 12, thereby physically isolating the two adjacent conductor parts 11 and avoiding the electrical connection between the two adjacent conductor parts 11 to affect the normal operation of each conductor part 11. Through the above structure, the frame of the communication device 2000 is used as the first communication antenna for communication with the outside world, so that the antenna group 1000 is realized externally, the limited space in the communication device 2000 is saved, and the space utilization of the antenna group 1000 in the communication device 2000 is improved. Moreover, the frame as the antenna group 1000 also makes the antenna group 1000 have fewer obstructions in the same working environment compared with the built-in antenna group 1000, thereby improving the stability and continuity of the signal of the communication device 2000 with the antenna group 1000.

[0043] It can be understood that when the conductive frame body 1 is enclosed as a frame, the position of the gap between the two adjacent conductor parts 11 can be selected according to actual needs, and the number of gaps can also be set according to actual needs to meet the coverage requirements of different frequency bands for different communication devices. For example, only 2G, 3G and 4G frequency bands need to be covered, or only WI FI frequency band needs to be covered, etc.

[0044] It should be noted that the material of the conductive frame body 1 is metal material, including but not limited to: aluminum alloy, titanium alloy, etc. The conductive frame body 1 of metal material improves the structural strength of the antenna group 1000 while ensuring the conductivity, and also improves the aesthetics of the communication device 2000 with the antenna group 1000.

[0045] Further, the conductive frame body 1 described above encloses a containing cavity 13, which is used for embedding other components (circuit board, battery, display, etc.) in the containing cavity 13 when the antenna group 1000 is used as the frame of the communication device 2000. The antenna group 1000 further includes a second communication antenna 3, which is accommodated in the containing cavity 13. By embedding the second communication antenna 3, the frequency range that can be covered by the antenna group 1000 is further improved, thereby improving the bandwidth of the antenna group 1000.

[0046] For the second communication antenna 3 described above, please refer to Figure 1 , the second communication antenna 3 includes a first coupling antenna 31 and a second coupling antenna 32, which are respectively used to adapt different communication frequency bands. To ensure the high bandwidth of the antenna group 1000.

[0047] For the first coupling antenna 31 described above, please refer to Figure 3 , the first coupling antenna 31 includes a feed branch 311 and a conductive film 312, which are spaced apart and form a distributed resonance structure through electromagnetic coupling rather than direct electrical connection. The coupling effect can excite multiple resonance modes, thereby expanding the operating bandwidth of the antenna or supporting multi-band communication, and the non-contact feed avoids impedance mismatch caused by welding or contact, and allows flexible tuning of the antenna resonance frequency by adjusting the spacing distance. The spaced apart manner provides an insulation safety distance, while the low loss characteristics of air medium are used to maintain the high frequency signal transmission efficiency of the antenna; the feed branch 311 is fixed to the external main plate to shorten the signal transmission path and reduce transmission loss, which is particularly important in the millimeter wave frequency band. The conductive film 312 is fixed to the external shell to facilitate adjustment of the spacing between the feed branch 311 and the conductive film 312 during actual installation and use.

[0048] Further, please refer to Figure 3 , the feed branch 311 is L-shaped; the feed branch 311 includes a first branch 3111 and a second branch 3112, which are perpendicular to each other; one end of the first branch 3111 is fixed to the external main plate, and the other end of the first branch 3111 is fixed to the second branch 3112, and the second branch 3112 is spaced apart and parallel to the conductive film 312. Through the L-shaped structure of the feed branch 311, the three-dimensional space inside the device is fully utilized, so that the first coupling antenna 31 is compact in layout when applied to the communication device 2000, saving space inside the communication device 2000. And the first branch 3111 and the second branch 3112 can respectively support different resonance frequencies, for example, the first branch 3111 (vertical part) is usually used for low frequency band (such as Sub-6GHz), and the second branch 3112 (horizontal part) is used for high frequency band (such as millimeter wave). By adjusting the length and width of the branch, the resonance points of each frequency band can be accurately controlled, further enhancing the bandwidth of the antenna group 1000. Furthermore, the first branch 3111 (vertical part) mainly generates a vertically polarized radiation field, and the second branch 3112 (horizontal part) generates a horizontally polarized radiation field. The combination of the two forms an omnidirectional radiation characteristic, which improves the signal reception capability of the antenna in complex environments.

[0049] In some embodiments, the antenna group 1000 further comprises a support frame 4 for supporting the conductive frame body 1 and connecting with the main body B of the communication device 2000, so as to ensure the structural strength of the frame of the communication device 2000 enclosed by the conductive frame body 1.

[0050] Further, the support frame 4 is provided with a plurality of limiting grooves, and the conductive frame body 1 is arranged in the limiting grooves to fix and limit the conductive frame body 1.

[0051] It should be noted that the structure of the support frame 4 includes but is not limited to: a frame structure, which is adapted to the shape of the conductive frame body 1; and a flat plate structure, which is used for placing the circuit board and can also be fixedly connected with the conductive frame body 1.

[0052] It should be noted that the limiting grooves are arranged to be adapted to the shape of the grounding end 111 of the conductor 11, so as to ensure that the conductive frame body 1 enclosed by the plurality of conductors 11 can form a complete frame.

[0053] In the embodiment, the antenna group 1000 comprises the conductive frame body 1 and the insulating section 2, wherein the conductive frame body 1 comprises a plurality of conductors 11, the plurality of conductors 11 are annularly arranged to form a frame for mounting the main body B of the communication device 2000, two adjacent conductors 11 are arranged to be spaced apart to form an avoiding opening 12, and the plurality of conductors 11 constitute a plurality of first communication antennas; the conductor 11 is provided with a grounding end 111 and a communication end 112, which are used for connecting with the main body B; and the insulating section 2 fills the avoiding opening 12, so as to physically isolate the two adjacent conductors 11 and avoid the electrical connection of the two adjacent conductors 11 to affect the normal work of each conductor 11. Through the above structure, the frame of the communication device 2000 is used as the first communication antenna for communication with the outside, so that the antenna group 1000 is realized to be external, the limited space in the communication device 2000 is saved, and the space utilization of the antenna group 1000 in the communication device 2000 is improved. Moreover, the frame as the antenna group 1000 also makes the antenna group 1000 have less shielding objects in the same working environment compared with the built-in antenna group 1000, and improves the stability and continuity of the signal of the communication device 2000 applied with the antenna group 1000.

[0054] The utility model also provides a communication device 2000 embodiment, please refer to Figure 1 , including backboard A, main body B, display screen C and above-mentioned antenna group 1000;The conductive frame body 1 is fixed to the backboard A, and the conductive frame body 1 and the backboard A jointly constitute lower shell, and the conductive frame body 1 and the backboard A enclose accommodating groove (not marked), and the main body B is fixed to the accommodating groove, and the conductive frame body 1 is arranged around the main body B, and the display screen C is fixed to the side of the conductive frame body 1 away from the backboard A, and the display screen C closes the slot opening of the accommodating groove.

[0055] It should be noted that the specific structure and function of the antenna group 1000 are described above, and will not be repeated here.

[0056] It can be understood that the communication device 2000 described above includes but is not limited to a mobile phone, a router, a wireless network card, a car audio system, and other devices that need to communicate with the outside world.

[0057] It should be noted that the conductor part 11 in the antenna group 1000 described above can be arranged according to actual use requirements, and the corresponding frequency band can be divided according to the use scenario of the communication device 2000. For example, when the antenna group 1000 is applied to a mobile phone, multiple conductor parts 11 need to cover multiple working frequency bands such as 2G, 3G, 4G, 5G, WiFi, and GPS. The number of conductor parts 11 is set according to the frequency band to be covered.

[0058] In order to facilitate understanding of the present application, the present application provides an embodiment of applying the antenna group 1000 to a mobile phone. Please refer to Figure 5 , the number of the plurality of conductor parts 11 of the conductive frame body 1 of the antenna group 1000 is 7, and the two coupling antennas are respectively the first coupling antenna 31 and the second coupling antenna 32, which together constitute nine antennas: one 4G low frequency (LB) antenna: ant(antenna) 1; three 4 / 5G medium-high frequency (MHB) antennas: ant(antenna) 2, ant(antenna) 5, ant(antenna) 9, one WiFi and GPS shared antenna: ant(antenna) 8, and four sub-6G MIMO antennas: ant(antenna) 3, ant(antenna) 4, ant(antenna) 6, ant(antenna) 7. Among them, ant(antenna) 3 is the first coupling antenna 31, and ant(antenna) 5 is the second coupling antenna 32.

[0059] It should be noted that each antenna is realized by controlling the Π-type matching circuit of the communication end 112 to realize the broadband of the frequency band.

[0060] Further, in the mobile phone, there is a material that uses a glass back cover, so in some embodiments, the conductive film 312 of the first coupling antenna 31 uses a light-transmitting material to improve the aesthetics when attached to the glass back cover of the mobile phone and other light-transmitting materials. The second coupling antenna 32 is arranged on the outer shell (i.e. the glass back cover of the mobile phone and other light-transmitting materials), and the second coupling antenna 32 also uses a light-transmitting material to improve the aesthetics of the second coupling antenna 32 applied to the mobile phone.

[0061] Specifically, in some embodiments, the conductive film 312 adopts ITO transparent conductive film 312. The ITO film is coated on the transparent glass by using a sputtering coating technology, and has high light transmittance and conductivity.

[0062] It should be noted that when the shell of the communication device 2000 such as a mobile phone is not a light-transmitting material, the conductive film 312 of the first coupling antenna 31 and the conductive film 312 of the second coupling antenna 32 can both adopt a light-blocking material.

[0063] Based on the application of the antenna group 1000 on the mobile phone, simulation experiments are also carried out, please refer to the drawings, the overall size of the antenna group 1000 is 165mm*75mm*7.5mm, and the position of the avoiding opening 12 (i.e. the position of the broken seam) and the position of the grounding end 111 (i.e. the position of the feed grounding point) can be adjusted according to needs. The size of the ant3 antenna is 20mm*6mm.

[0064] The RL curve of the antenna is as shown in Figure 6 and Figure 7 As can be judged from the S parameter curve, the sub-6G MIMO antenna, the 4 / 5G medium-high frequency (MHB) antenna, the 4G low frequency (LB) antenna and the WiFi and GPS shared antenna are all below the reference level of-6dB, which meets the actual use requirements.

[0065] The isolation degree of the antenna group 1000 is as shown in Figure 8 , Figure 9 and Figure 10 The isolation degree of the sub-6G MIMO antenna group 1000 is all below-10dB, the isolation degree between the three 4 / 5G medium-high frequency (MHB) antennas is below-20dB, the interference between the antennas is small, the required signals can be more accurately received, and the quality and reliability of the signal transmission are high.

[0066] It should be noted that the specification and drawings of the utility model give the preferred embodiments of the utility model, but the utility model can be realized by many different forms, and is not limited to the embodiments described in the specification, and the embodiments are not as additional limitations on the content of the utility model, and the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Furthermore, the above technical features continue to combine, form various embodiments not listed above, and are considered to be within the scope of the utility model specification; further, those skilled in the art can improve or transform according to the above description, and all these improvements and transformations should belong to the protection scope of the utility model claims.
