Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] As mentioned in the background section, existing technologies commonly employ a structural design with four or more slots in the metal frame. This divides the metal frame into multiple independent radiating elements, which respectively constitute end-fed antennas, side-fed antennas, and slot-coupled antennas, to achieve independent excitation and radiation control of low-frequency (600–960MHz), mid-frequency (1.7–2.7GHz), high-frequency (3.3–4.2GHz), and Wi-Fi / satellite bands. Existing technologies typically use four to six slots to construct independent radiators, with each additional slot adding an independent antenna element. However, this structure leads to a decrease in the mechanical strength of the metal frame structure as the number of slots increases. Therefore, to address the aforementioned technical problems, the antenna module proposed in this application includes a device frame 110 and multiple antenna components 40. By providing only two physical gaps on the device frame 110, the device frame 110 is divided into a first frame 200 and a second frame 300. The first frame 200 and the second frame 300 are each an integral structure. The first frame 200 serves as a radiator, carrying the signal excitation of the multiple antenna components 40. That is, by setting at least two antenna components 40 on the first frame 200, and at least two antenna components 40 sharing the first frame 200 as a radiator, signal reception or transmission is achieved through frequency band isolation. This application solves the problem in the prior art where the number of gaps in the terminal device is too large, resulting in a weakening of the mechanical strength of the frame structure.

[0026] Please refer to Figures 1 to 18This application provides an antenna module, comprising: a device frame 110, the device frame 110 including a first frame 200 and a second frame 300, the first frame 200 and the second frame 300 being integral structures, the first frame 200 and the second frame 300 forming the device frame 110, a first gap 201 being provided between the first end of the first frame 200 and the first end of the second frame 300, and a second gap 202 being provided between the second end of the first frame 200 and the second end of the second frame 300; a plurality of antenna components 40, at least some of the antenna components 40 being disposed on the device frame 110; wherein, at least two antenna components 40 are disposed on at least one of the first frame 200, and the at least two antenna components 40 disposed on the first frame 200 respectively realize receiving or transmitting signals through frequency band isolation.

[0027] The device frame 110 provided in this application is a metal frame structure, made of aluminum alloy by stamping. The first frame 200 is the long side metal frame of the device, with a length of 150mm to 180mm, and serves as the main radiator of the main communication antenna. The second frame 300 is the short side metal frame of the device, with a length of 90mm to 110mm, and serves as the auxiliary radiator of the positioning and auxiliary antenna. The first frame 200 and the second frame 300 form the device frame 110. The first frame 200 and the second frame 300 are respectively integral structures to form the main mechanical support and electromagnetic radiation platform of the device shell, thereby improving the structural rigidity.

[0028] A first gap 201 and a second gap 202 are provided between the first frame 200 and the second frame 300 to physically isolate the first frame 200 and the second frame 300. The first gap 201 and the second gap 202 are respectively provided at both ends of the first frame 200 and are symmetrically distributed around the long side, which ensures both structural strength and appearance consistency, while also interrupting the continuity of the metal, forming two independent antenna radiation excitation areas.

[0029] By setting the first frame 200 and the second frame 300, and by only setting the first gap 201 and the second gap 202 on the device frame 110, the continuity of the metal body is improved, the structural strength of the body is greatly enhanced, and the problem of fragmented frame structure and poor bending and torsional resistance caused by the need for more than four gaps to isolate antennas in traditional equipment is avoided, thus significantly improving the appearance integrity. At least two antenna components are integrated into the same metal frame (first frame 200), and independent transmission and reception of the same frequency / near frequency antennas are achieved through a dedicated frequency band isolation circuit. Different antenna components do not interfere with each other when operating in the same frequency band, and no additional physical isolation or shielding layer is required, thus improving space utilization. With the first frame 200 as the main radiator, the conductivity is good and the surface area is large, and the radiation efficiency is significantly improved, solving the problem of excessive gaps in the terminal equipment in the prior art, which weakens the mechanical strength of the frame structure.

[0030] Specifically, the width of the first gap 201 is 1mm to 2mm, and the width of the second gap 202 is 1mm to 2mm.

[0031] Specifically, plastic brackets are respectively embedded in the first gap 201 and the second gap 202 to isolate the first frame 200 and the second frame 300.

[0032] In the first embodiment of this application, as Figure 2 As shown, the antenna module further includes: a first DC blocking component 601, the input terminal of which is connected to the first frame 200, the output terminal of which is used for grounding, a first radiating conductor 210 formed at the portion of the first frame 200 between the connection point of the first DC blocking component 601 and the first frame 200 and the first gap 201, and a second radiating conductor 220 formed at the portion of the first frame 200 between the connection point of the first DC blocking component 601 and the first frame 200 and the second gap 202; and a plurality of antenna components 40 including: a first antenna component 400, the output terminal of which is connected to the first radiating conductor 210, and the first antenna component 400 receiving or transmitting signals of the first frequency band through the first radiating conductor 210; and a second antenna component 500, the output terminal of which is connected to the second radiating conductor 220, and the first antenna component 400 receiving signals of the first frequency band through the second radiating conductor 220.

[0033] In this embodiment, by setting a first DC blocking component 601 in the middle of the first frame 200, the original continuous metal frame is divided into two independent resonant radiators (a first radiating conductor and a second radiating conductor), realizing the layout of dual antennas sharing the same metal frame segment; the two antenna components operate in the same frequency band, such as the LTE low-frequency band (Long Term Evolution), and high isolation between the main / diversity antennas of the same frequency is achieved through physical location separation and grounding isolation, effectively suppressing signal coupling, improving SAR (Specific Absorption Rate) performance and receiving sensitivity, overcoming the problem of isolation degradation caused by the small spacing of low-frequency co-frequency antennas in traditional solutions, and realizing the integrated dual antennas and high performance coexistence.

[0034] Furthermore, the first antenna assembly 400 and the second antenna assembly 500 are symmetrically connected to both ends of the first frame 200, and their connection points are symmetrically arranged relative to the first DC blocking assembly 601. Using this DC blocking component as the central grounding node, a high-isolation co-location design for low-frequency (600–960MHz) main and diversity antennas on a single metal frame is achieved. This solves the technical dilemma of low-frequency co-location isolation, significantly improving MIMO performance and communication stability without shielding, partitions, or additional space occupation. It also enhances receiving sensitivity in weak signal scenarios (subways, basements, high-rise buildings), significantly improving user experience. The first DC blocking assembly 601, connected to the ground plane of the printed circuit board 20, forms a controllable current discharge channel, guiding low-frequency radiated energy to the internal ground plane of the device, rather than flowing towards the human head. This significantly reduces the specific absorption rate, allowing for mandatory certifications such as FCC (Federal Communications Commission), CE (Conformité Européenne), GCF (Global Certification Forum), and SRRC (State Radio Regulation of China) without the need for additional shielding.

[0035] The first antenna assembly 400 and the second antenna assembly 500 are designed as co-radiators for LTE (Long Term Evolution) at the same frequency. In conventional designs, the co-radiating antennas are designed with mid-to-high frequency or ultra-high frequency frequencies to reduce co-frequency interference. This application provides a co-radiator design scheme for a full-band LTE main antenna and diversity antenna layout, covering low-frequency / mid-frequency / high-frequency bands. In the co-frequency antenna design of two antennas, in the limited space of a metal plate, the lower the frequency band and the higher the isolation risk between the two antennas, the more likely it is to lead to a decrease in the performance of the active antenna, which becomes a technical problem for the antennas of the terminal product. This application reduces the number of gaps and provides a solution to the low-frequency co-frequency isolation of the two antennas.

[0036] Specifically, the first antenna assembly 400 is a 5G / 4G cellular main antenna, and its signal feed is connected to the first frame 200 via a microstrip line or a flexible printed circuit board. The first antenna assembly 400 adopts the principle of a loop antenna, and the antenna resonant frequency covers the entire frequency band of 5G and cellular antennas, including low frequency, mid frequency, and high frequency. The low frequency covers 600MHz~960MHz, the mid frequency covers 1710MHz~2170MHz, and the high frequency covers 2300MHz~2690MHz.

[0037] Furthermore, the first antenna assembly 400 includes a first signal feed 420, a first impedance tuning circuit, and a first switching aperture tuning circuit 410 connected in sequence. The first signal feed 420 is used to connect to a first preset chip, and the output terminal of the first switching aperture tuning circuit 410 is connected to the first frame 200. When the communication frequency band is switched, the first switching aperture tuning circuit 410 adjusts the radiation path length of the current on the first frame 200. Then, the first impedance tuning circuit adjusts the input impedance of the first frame 200 so that the first frame 200 transmits and receives signals of the first preset frequency band. By combining the first impedance tuning circuit and the first switching aperture tuning circuit 410, different antenna operating frequencies are tuned to achieve good antenna performance; it supports the B71 / B14 / B17 low-frequency bands and meets the signal master transmission and reception functions of SA (Standalone) and NSA (Non-Standalone).

[0038] Specifically, the second antenna assembly 500 is a 5G / 4G cellular diversity antenna, and its signal feed is connected to the first frame 200. The second antenna assembly 500 adopts the principle of a loop antenna, and the antenna resonant frequency covers the entire frequency band of 5G and cellular antennas, including low frequency, mid frequency, and high frequency. The low frequency covers 600MHz~960MHz, the mid frequency covers 1710MHz~2170MHz, and the high frequency covers 2300MHz~2690MHz.

[0039] Furthermore, the second antenna assembly 500 includes a second signal feed 520, a second impedance tuning circuit, and a second switching aperture tuning circuit 510 connected in sequence. The second signal feed 520 is used for connection to a second preset chip, and the output terminal of the second switching aperture tuning circuit 510 is connected to the first frame 200. When the communication frequency band is switched, the second switching aperture tuning circuit 510 adjusts the radiation path length of the current on the first frame 200. Subsequently, the first impedance tuning circuit adjusts the input impedance of the first frame 200 so that the first frame 200 receives the second preset frequency band signal. By combining the second impedance tuning circuit and the second switching aperture tuning circuit 510, different antenna operating frequencies can be tuned to achieve good antenna performance; it supports the North American B71 / B14 / B17 low-frequency bands and meets the signal reception functions of 4G, 5G SA, and NSA.

[0040] Specifically, such as Figure 2As shown, the first DC blocking component 601 includes a DC blocking member 611, which is a grounding network located at the center of the first frame 200. Its input terminal is directly soldered to the center point of the first frame 200, and its output terminal is connected to the ground plane of the printed circuit board. Further, the antenna module also includes a first filtering DC blocking circuit 620, whose input terminal is connected to the first frame 200 and whose output terminal is used for grounding; and a second filtering DC blocking circuit 630, whose input terminal is connected to the first frame 200 and whose output terminal is used for grounding. The connection points of the first filtering DC blocking circuit 620 and the first frame 200, and the connection points of the second filtering DC blocking circuit 630 and the first frame 200, are symmetrically arranged on both sides of the input terminal of the DC blocking member 611.

[0041] In this way, by setting up symmetrically distributed first and second filter DC blocking circuits 620 and 630, respectively connected to the first frame 200 with the connection points symmetrically arranged around the DC blocking component 611, high isolation and collaborative operation of multiple antennas in the mid-to-high frequency band (1.7–4.2 GHz) on a shared metal frame is achieved. This solves the problem of severe coupling between SUB6G and MHB band antennas, significantly suppresses common-mode radiation, improves the overall EMC performance, reduces interference to modules such as WiFi, Bluetooth, and NFC, and significantly reduces radiated emissions. It also enables independent tuning and frequency band decoupling of multi-band antennas, avoids mutual interference between B21, MHB, and SUB6G bands, and increases the number of carrier aggregation combinations. Replacing the complex structure of traditional multi-slit, multi-shielded, and multi-independent antennas, only two small filter circuits are needed to achieve multi-band and multi-antenna collaboration within a single frame, resulting in a simple structure and low cost.

[0042] Specifically, the distance between the connection point of the first filter DC blocking circuit 620 and the first frame 200 and the connection point of the DC blocking component 611 and the first frame 200 is A1, where 3mm ≤ A1 ≤ 5mm. Thus, when A1 < 3mm, the antenna resonant frequency shifts significantly, and the radiation efficiency decreases; when A1 > 5mm, the isolation deteriorates significantly, and electromagnetic interference exceeds the standard. By limiting the range of A1, high isolation of the mid-to-high frequency band antenna is achieved, reducing interference.

[0043] Furthermore, such as Figure 5As shown, the first aperture tuning circuit 410 and the second aperture tuning circuit 510 respectively include a SAR functional unit M13, a band-stop functional unit M14 and an impedance functional unit M15 connected in sequence. The input terminal of the SAR functional unit M13 is connected to a preset radio frequency chip, and the output terminal of the impedance functional unit M15 is connected to the first frame 200. The first aperture tuning circuit 410 and the second aperture tuning circuit 510 also include a TVS diode M12. The TVS diode M12 is connected in parallel with the SAR functional unit M13, and the output terminal of the TVS diode M12 is used for grounding.

[0044] like Figure 5 and Figure 6 As shown, the band-stop functional unit M14 includes a first resistive-capacitive-inductive element M141 and a second resistive-capacitive-inductive element M142. The first resistive-capacitive-inductive element M141 and the second resistive-capacitive-inductive element M142 are connected in parallel or in series. In conjunction with impedance tuning, filtering and decoupling are performed to improve the isolation of the dual antennas.

[0045] This application provides an optional embodiment in which the antenna module includes: a filter tuning component 350, the input terminal of which is connected to a second frame 300, the output terminal of which is grounded, and a third radiating conductor 310 formed at the portion of the second frame 300 between the connection point of the filter tuning component 350 and the second frame 300 and a second gap 202; and a first grounding circuit 314, the input terminal of which is connected to the second frame 300, the output terminal of which is grounded, and the portion of the second frame 300 between the connection point of the filter tuning component 350 and the second gap 202. 4. The portion between the connection point of the second frame 300 and the connection point of the filter tuning component 350 and the second frame 300 forms a fourth radiating conductor 320; the plurality of antenna components 40 further includes: a third antenna component 330, the output terminal of the third antenna component 330 being connected to the third radiating conductor 310, the third antenna component 330 transmitting or receiving signals of the second frequency band through the third radiating conductor 310; and a fourth antenna component 340, the output terminal of the fourth antenna component 340 being connected to the fourth radiating conductor 320, the fourth antenna component 340 receiving signals of the second frequency band through the fourth radiating conductor 320.

[0046] In this embodiment, two independent SUB-6G band radiating conductors (the third and fourth radiating conductors) are constructed on the second frame 300 through the coordinated action of the filter tuning component 350 and the first grounding circuit 314. This allows the SUB-6G main and diversity antennas to share the same metal frame segment, and the filter circuit suppresses harmonics and spurious signals, significantly improving antenna directivity and received signal-to-noise ratio. This design avoids the space waste and cost increase caused by adding independent antenna cavities or FPCs (Flexible Printed Circuits), achieving efficient multiplexing of dual antennas on a single frame, meeting the MIMO (Multiple Input Multiple Output) performance requirements of the n77 / n78 / n79 bands, while reducing the overall stacking height and BOM (Bill of Materials) cost.

[0047] Specifically, the third antenna assembly 330 serves as the main antenna, used for transmitting / receiving signals in the second frequency band (B21 1.45–1.52GHz + SUB6G 3.3–4.2GHz). The third antenna assembly 330 employs a loop antenna design principle, with its resonant frequency covering the B21 / B32 / B11 antenna bands and the SUB-6G antenna band for main antenna function. The B21 / B11 / B32 frequencies cover 1447MHz~1520MHz, and the n77 / n78 / n79 frequencies cover 3.3GHz~4.2GHz, supporting B21 / B32 / B11 / n77 / n78 / n79. Its main functions meet 4G communication protocols, supporting main transmission and reception functions in the operator's 4GB21 / B11 bands; the SUB-6G antenna band provides MIMO main signal transmission and reception functions, meeting 5G communication protocols, and supporting SA and NSA signal transmission and reception functions.

[0048] Specifically, the fourth antenna assembly 340 is used to receive signals in the second frequency band, serving as a diversity antenna for the SUB-6G band.

[0049] Specifically, the filtering and tuning component 350 includes: a first filtering and tuning circuit 351, the input terminal of which is connected to the portion of the second frame 300 near the third antenna assembly 330, and the output terminal of which is grounded; a second filtering and tuning circuit 352, the input terminal of which is connected to the portion of the second frame 300 near the fourth antenna assembly 340, and the output terminal of which is grounded; the connection points of the first filtering and tuning circuit 351 and the second frame 300 and the second filtering and tuning circuit 352 are spaced apart on the third radiating conductor; both the first filtering and tuning circuit 351 and the second filtering and tuning circuit 352 are used to block signals in a third frequency band, the frequency of which is lower than the frequency of the second frequency band. In this way, by setting the first filter tuning circuit 351 and the second filter tuning circuit 352 on the second frame 300, and connecting them to the adjacent areas of the third antenna assembly 330 and the fourth antenna assembly 340 respectively, and both of them are used to block the third frequency band signal with a frequency lower than the second frequency band, the blocking of low frequency band signals is realized in the metal co-electrode antenna system, ensuring the stable transmission of high frequency band signals, effectively suppressing low frequency cellular signals such as B28, B5, and B8 from entering the B21 / SUB6G main diversity radiation area, significantly improving the efficiency of the high frequency antenna, improving radiation efficiency, and solving the problem of poor performance caused by low frequency current interference in traditional solutions.

[0050] This application provides an optional embodiment, such as... Figure 3 As shown, the third radiating conductor 310 and the fourth radiating conductor 320 are integrally connected, and the second gap 202 is disposed between the third radiating conductor 310 and the first frame 200; the extension direction of the third radiating conductor 310 and the extension direction of the fourth radiating conductor 320 are set at an angle; and / or, the first frame 200 extends along a straight trajectory, and the extension direction of the third radiating conductor 310 is consistent with the extension direction of the first frame 200.

[0051] In this embodiment, by designing the third radiating conductor 310 and the fourth radiating conductor 320 as an integral connection with an angled structure, spatial polarization isolation (such as vertical polarization and horizontal polarization) is achieved in a limited space, which significantly improves the polarization isolation between the SUB-6G main / diversity antennas and effectively suppresses MIMO signal mutual coupling. At the same time, by making the extension direction of the third radiating conductor 310 consistent with that of the first frame 200, a reasonable structural layout and unified processing technology are achieved, which facilitates stamping and assembly, improves production yield, reduces mold complexity, and achieves dual optimization of performance and manufacturing cost.

[0052] An optional embodiment provided in this application, such as Figure 2As shown, the antenna module further includes: a first housing 120, with a device frame 110 surrounding the periphery of the first housing 120; the plurality of antenna components 40 further include: a sixth antenna component 710, disposed on the first housing 120, used to receive or transmit signals of the fifth frequency band; a seventh antenna component 720, disposed on the first housing 120, used to receive or transmit signals of the sixth frequency band; an eighth antenna component 730, disposed on the first housing 120, used to receive or transmit signals of the seventh frequency band; and a ninth antenna component 740, disposed on the first housing 120, used to receive or transmit signals of the eighth frequency band; wherein, the sixth antenna component 710, the eighth antenna component 730, and the seventh antenna component 720 are spaced apart along the length direction of the first housing 120, and the ninth antenna component 740 and the seventh antenna component 720 are spaced apart along the width direction of the first housing 120, with the sixth antenna component 710 and the seventh antenna component 720 disposed at both ends of the first housing 120.

[0053] In this embodiment, the first housing 120 is the non-metallic main structure inside the device, serving as the mounting platform for the antenna components. The sixth antenna component 710 is a B21+5G / 4G MHB (Mid-High Band, a mid-to-high frequency MIMO diversity antenna, with resonant frequencies covering 5G antennas, mid-frequency / high-frequency / sub-6G antennas, and frequency coverage of the B21 band 1447MHz~1520MHz and 1710MHz~4.2GHz, supporting multi-frequency 5G MIMO technology and meeting SA and NSA signal reception requirements. The seventh antenna component 720 is a WiFi antenna, implemented using FPC (Flexible Printed Circuit) technology, covering a frequency band of 5.15GHz~7.2GHz, supporting WiFi 5 / WiFi 6 / WiFi 6E / WiFi 7. The structural area maximizes the excitation of good WiFi antenna performance, meeting the usage scenarios and performance indicators of users in different countries. The eighth antenna component 730 is a 5G / 4G MHB ENDC antenna, using FPC technology and PIFA (Planar Inverted-Functional) technology. Designed based on the principle of a planar inverted F-shaped antenna, its main function is to serve as an ENDC (End-of-Card) transmitting antenna for mid-to-high frequencies in 5G / 4G networks. It covers a frequency bandwidth of 1710MHz to 2.69GHz, covering B1 / 2 / 3 and supporting multi-frequency 5G MIMO technology, meeting the requirements of SA (Standalone) and NSA (Non-Standalone) network architectures. It features non-standalone (NSA) signal transmission and reception capabilities. The ninth antenna assembly 740 is a SUB6G band MIMO diversity antenna. Its primary function is as an ENDC (End-of-Card) transmission antenna for mid-to-high frequencies in 5G / 4G, covering a frequency bandwidth of 1710MHz~2690MHz. The ninth antenna assembly 740 is vertically polarized. Through the sixth to ninth antenna assemblies 710, high-frequency WiFi, satellite enhancement, and other non-cellular antennas are systematically integrated onto a non-metallic casing (such as engineering plastic). Using a dual-track antenna architecture of a metal frame and a plastic casing, low frequencies are handled by the metal frame, while high frequencies are radiated independently by the casing antennas, avoiding interference from metal shielding on high-frequency signals and improving the radiation efficiency of high-frequency antennas such as WiFi 7, millimeter wave, and ultra-wideband. All antenna assemblies (sixth to ninth antenna assemblies 740) are completely hidden inside the casing, with no openings or metal patches on the exterior, enhancing the aesthetics and unibody design of the device.

[0054] In a second embodiment of this application, the antenna module further includes: a first DC blocking component 601, the input terminal of which is connected to the first frame 200, the output terminal of which is grounded, and a first radiating conductor 210 formed at the portion of the first frame 200 between the connection point of the first DC blocking component 601 and the first frame 200 and the first gap 201; and a second DC blocking component 602, the input terminal of which is connected to the first frame 200, the output terminal of which is grounded, and a first radiating conductor 210 formed at the portion of the first frame 200 between the connection point of the first DC blocking component 601 and the first gap 201; and a second DC blocking component 602, the input terminal of which is connected to the first frame 200, the output terminal of which is grounded, and a first radiating conductor 210 formed at the portion of the first frame 200 between the connection point of the first DC blocking component 601 and the first gap 201. The portion between the connection point of the first frame 200 and the connection point of the first DC blocking component 601 and the first frame 200 forms a second radiating conductor 220; the plurality of antenna components 40 include: a first antenna component 400, the output terminal of the first antenna component 400 being connected to the first radiating conductor 210, the first antenna component 400 receiving or transmitting signals of the first frequency band through the first radiating conductor 210; a second antenna component 500, the output terminal of the second antenna component 500 being connected to the second radiating conductor 220, the second antenna component 500 receiving signals of the first frequency band through the second radiating conductor 220.

[0055] In this embodiment, dual DC blocking components are spaced apart in the middle of the first frame 200, dividing the metal frame into three independent regions. The central region forms the second radiating conductor 220, and the two side regions form the first radiating conductors 210, realizing a three-segment antenna radiation structure. This structure can support dual antennas to operate simultaneously in the same low-frequency band (such as B71 / B28). By precisely controlling the position of the DC blocking components and the grounding path, better impedance matching and radiation efficiency are achieved, and near-field coupling between antennas is significantly reduced. This allows the low-frequency main / diversity antennas to still meet the operator's OTA (Over-The-Air) certification requirements in a compact space, improving communication reliability.

[0056] This application provides an optional embodiment in which the antenna module includes: a filter tuning component 350, the input terminal of which is connected to a first frame 200, the output terminal of which is grounded, and a third radiating conductor 310 formed at a portion of the first frame 200 between the connection point of the filter tuning component 350 and the first frame 200 and the connection point of the second DC blocking component 602 and the first frame 200; and a fourth radiating conductor 320 formed at a portion of the first frame 200 between the connection point of the filter tuning component 350 and the first frame 200 and the second gap 202. The plurality of antenna components 40 further include: a third antenna component 330, the output terminal of which is connected to the third radiating conductor 310, and the third antenna component 330 transmitting or receiving signals of a second frequency band through the third radiating conductor 310; and a fourth antenna component 340, the output terminal of which is connected to the fourth radiating conductor 320, and the fourth antenna component 340 receiving signals of the second frequency band through the fourth radiating conductor 320.

[0057] In this embodiment, by arranging the filter tuning component 350 on the first frame 200, a cross-frame integrated design of the SUB-6G main / diversity antenna is achieved, breaking the traditional layout limitation of concentrating the SUB-6G antenna on the short side. By using a shared metal structure to construct dual radiating conductors, the SUB-6G antenna can be distributed in the middle and end of the long side, significantly improving the antenna radiation area and ground return path, and enhancing the high-frequency band radiation efficiency. At the same time, the filter circuit accurately suppresses the mutual interference between the B21 and n77 frequency bands, achieving multi-frequency band coexistence without interference, meeting the frequency band combination requirements of global multi-operator networks, and improving the global roaming capability of the terminal.

[0058] This application provides an optional embodiment in which the third radiating conductor 310 and the fourth radiating conductor 320 are integrally connected, and the second gap 202 is disposed between the fourth radiating conductor 320 and the second frame 300; the extension direction of the third radiating conductor 310 and the extension direction of the fourth radiating conductor 320 are set at an angle; and / or, the first radiating conductor 210 and the second radiating conductor 220 extend along a straight trajectory, and the extension direction of the third radiating conductor 310, the extension direction of the first radiating conductor 210 and the extension direction of the second radiating conductor 220 are consistent.

[0059] In this implementation, by unifying the extension of the SUB-6G radiating conductor and the LTE radiating conductor along a straight line (the extension direction of the third radiating conductor 310, the extension direction of the first radiating conductor 210, and the extension direction of the second radiating conductor 220), a linear layout of multi-band antennas in the same plane is achieved, improving the overall structural rationality and electromagnetic consistency. The angled design further enhances polarization isolation, enabling the SUB-6G main / diversity antennas to achieve spatial decoupling within the same metal frame segment. This avoids signal obstruction and enhanced coupling problems caused by traditional short-side dense layouts, improves the overall antenna efficiency, and optimizes the overall EMC (Electromagnetic Compatibility) performance, meeting FCC / CE (Federal Communications Commission and European Conformity) certification requirements.

[0060] This application provides an optional embodiment in which the antenna module further includes: a second grounding circuit 362, the input terminal of which is connected to the second frame 300, the output terminal of which is used for grounding, and a fifth radiating conductor 370 formed at the portion of the second frame 300 located between the first gap 201 and the connection point between the second grounding circuit 362 and the second frame 300; the plurality of antenna assemblies 40 further includes: a fifth antenna assembly 361, the output terminal of which is connected to the fifth radiating conductor 370, and the fifth antenna assembly 361 receiving or transmitting signals of the fourth frequency band through the fifth radiating conductor 370; wherein, the fifth radiating conductor 370 has a zigzag structure.

[0061] In this embodiment, by setting a zigzag radiating conductor (fifth radiating conductor 370) in the short side region, the GPS / BDS / Galileo satellite navigation antenna is efficiently integrated. The zigzag structure effectively extends the electrical length, making up for the problem of insufficient space in the short side, without the need for an additional FPC or independent antenna module.

[0062] Furthermore, the fifth antenna assembly 361 is a satellite positioning antenna. The antenna adopts the principle of loop antenna design, and its main functions are satellite positioning and navigation. It supports GPS, BDS (BeiDou Navigation Satellite System), and Galileo (European Union Global Navigation Satellite System) covering the frequency band of 1575MHz~1620MHz. The fifth antenna assembly 361 also includes the function of SUB-6G MIMO diversity antenna. The circuit is designed as a two-in-one unit to maximize the application of structural space to improve the performance of sub6G antenna. By setting up a fifth antenna assembly 361 and a second grounding circuit 362, and arranging them spaced apart on the second frame 300, an independent fourth radiating conductor 320 is formed, constructing a controllable current loop. Through spatial isolation between the feed point and the grounding point, the current is forced to radiate only in the fourth radiating conductor 320, improving the isolation between antennas. High-efficiency passive radiation in the satellite positioning frequency band (1575MHz) is achieved. The fourth radiating conductor 320, as a λ / 4 monopole structure, requires no additional patch and supports GPS / BDS / Galileo multi-mode positioning, improving positioning accuracy. The second grounding circuit 362 is an intelligent impedance matching network that integrates inductor-capacitor filtering and matching functions, improving the accuracy of the antenna input impedance and significantly enhancing weak signal reception and anti-interference capabilities.

[0063] In the third embodiment of this application, as Figure 4As shown, the antenna module further includes: a first DC blocking component 601, the input terminal of which is connected to the first frame 200, and the output terminal of which is grounded; a second DC blocking component 602, the input terminal of which is connected to the first frame 200, and the output terminal of which is grounded, wherein the portion of the first frame 200 located between the connection point of the second DC blocking component 602 and the first frame 200 and the second gap 202 forms a second radiating conductor 220; and a third DC blocking component 603, the input terminal of which is connected to the first frame 200, and the output terminal of which is grounded, wherein the second DC blocking component 602 and the first DC blocking component 601... The first and third DC blocking components 601 and 603 are sequentially and spaced apart on the first frame 200. The portion of the first frame 200 located between the connection point of the first DC blocking component 601 and the first frame 200 and the connection point of the third DC blocking component 603 and the first frame 200 forms a first radiating conductor 210. The plurality of antenna components 40 include: a first antenna component 400, the output terminal of which is connected to the first radiating conductor 210, and the first antenna component 400 receiving or transmitting signals of the first frequency band through the first radiating conductor 210; and a second antenna component 500, the output terminal of which is connected to the second radiating conductor 220, and the second antenna component 500 receiving signals of the first frequency band through the second radiating conductor 220.

[0064] In this embodiment, a three-segment DC blocking component layout forms three independent electrical zones on the first frame, supporting the parallel operation of multiple groups of antennas at the same frequency (such as main antenna + diversity antenna + auxiliary antenna), significantly improving the flexibility of antenna configuration. This structure enables regional control of multiple antenna functions, supports dynamic frequency band switching and MIMO mode switching, and provides a structural foundation for supporting 5G-Advanced carrier aggregation in the future. At the same time, the three DC blocking structure enhances the symmetry of the ground return path, reduces common-mode interference, and improves the overall EMC performance and SAR compliance capability.

[0065] This application provides an optional embodiment in which the first radiating conductor 210 extends in a straight trajectory; the second radiating conductor 220 includes a first connecting segment 221 and a second connecting segment 222 of an integral structure, the end of the second connecting segment 222 away from the first connecting segment 221 is connected to the second blocking component 602, and the end of the first connecting segment 221 away from the second connecting segment 222 forms a second gap 202 with the second frame 300; wherein the extension direction of the first connecting segment 221 and the extension direction of the second connecting segment 222 are set at an angle, and the extension direction of the second connecting segment 222 is consistent with the extension direction of the first radiating conductor 210.

[0066] In this embodiment, the second radiating conductor adopts an L-shaped bending structure, which achieves a natural connection between the antenna radiator and the corner of the frame without increasing the size of the metal frame. This effectively utilizes the corner space as a radiation extension, improving the radiation efficiency of the low-frequency band (B71 / B28). The L-shaped structure makes the antenna current path closer to the edge of the device, enhancing near-field coupling performance and significantly improving the low-frequency radiation gain (+1.5~2.5dB). At the same time, it avoids the decrease in structural strength caused by the close proximity of the seam, maximizing space utilization and structural reliability.

[0067] This application provides an optional embodiment in which the antenna module further includes: a filter tuning component 350, the input terminal of which is connected to the first frame 200, and the output terminal of which is grounded; a third radiating conductor 310 is formed at the portion of the first frame 200 between the connection point of the filter tuning component 350 and the first frame 200 and the connection point of the first DC blocking component 601 and the first frame 200; a fourth radiating conductor 320 is formed at the portion of the first frame 200 between the connection point of the filter tuning component 350 and the first frame 200 and the connection point of the second DC blocking component 602 and the first frame 200; the plurality of antenna components 40 further includes: a third antenna component 330, the output terminal of which is connected to the third radiating conductor 310, and the third antenna component 330 transmits or receives signals of the second frequency band through the third radiating conductor 310; and a fourth antenna component 340, the output terminal of which is connected to the fourth radiating conductor 320, and the fourth antenna component 340 receives signals of the second frequency band through the fourth radiating conductor 320.

[0068] In this embodiment, the layout achieves the sequential distribution of the SUB-6G main and diversity antennas (third antenna assembly 330 and fourth antenna assembly 340) on the same long side. The third antenna assembly 330 transmits or receives signals of the second frequency band through the third radiating conductor 310, and the fourth antenna assembly 340 receives signals of the second frequency band through the fourth radiating conductor 320. The length and impedance of the radiator are precisely controlled by the filtering and tuning assembly 350, enabling the two antennas to achieve precise frequency resonance and high isolation, avoiding the decrease in MIMO throughput caused by poor antenna symmetry in traditional solutions. This structure is compatible with global B21 / B32 / B11 and n77 / n78 / n79 frequency bands, supports 5G SA / NSA modes, and significantly improves the global applicability and market competitiveness of the terminal.

[0069] This application provides an optional embodiment in which a fifth radiating conductor 370 is formed at the portion of the first frame 200 located between the connection point of the third blocking component 603 and the first frame 200 and the first gap 201; the plurality of antenna components 40 further include: a fifth antenna component 361, the output terminal of the fifth antenna component 361 being connected to the fifth radiating conductor 370, the fifth antenna component 361 receiving or transmitting signals of the fourth frequency band through the fifth radiating conductor 370; wherein, the fifth radiating conductor 370 has a zigzag structure.

[0070] In this embodiment, a zigzag-shaped fifth radiating conductor 370 is provided near the first gap 201 to integrate B21 / B11 / B32 LTE band antennas. Its zigzag structure effectively extends the electrical length, allowing the B21 antenna, which should be placed on the short side, to be deployed at the long side end, achieving spatial decoupling from the SUB-6G antenna; avoiding mutual interference when the B21 and n77 bands share the same radiator, improving the radiation efficiency and S11 performance of the B21 band, meeting the operator's coverage requirements for the B21 band, and achieving multi-country band compatibility design.

[0071] In a first embodiment of this application, the device frame 110 includes two first connecting frames 111 and two second connecting frames 112, which are sequentially and alternately connected to form the device frame 110; a first gap 201 and a second gap 202 are spaced apart on one of the two first connecting frames 111, wherein the length of the first connecting frame 111 is greater than the length of the second connecting frame 112.

[0072] The device frame 110 is a rectangular frame structure formed by alternatingly connecting two first connecting frames 111 and two second connecting frames 112. The two first connecting frames 111 are located on the long side of the device, and the two second connecting frames 112 are located on the short side. A first gap 201 and a second gap 202 are provided on one of the first connecting frames 111, and they are spaced apart along the length of the first connecting frame 111, so that both gaps are located on the same long side structure of the device, making effective use of the length of the antenna radiator. One of the first connecting frames 111 forms a continuous metal radiating segment between the first gap 201 and the second gap 202, serving as the main structure of the high-frequency antenna. The first gap 201 and the second gap 202 serve as the current breakpoint and the boundary of the feed path, respectively. This layout avoids the problems of reduced radiation efficiency and enhanced antenna coupling caused by the dispersion of gaps in multi-slot structures, simplifies the freedom of antenna design, and allows the main and diversity antennas to be arranged symmetrically along the radiating segment, realizing a common radiator structure using the same metal frame.

[0073] In a second embodiment of this application, the device frame 110 includes two first connecting frames 111 and two second connecting frames 112, which are sequentially and alternately connected to form the device frame 110; a first gap 201 is disposed on one of the two first connecting frames 111, and a second gap 202 is disposed on one of the two second connecting frames 112; wherein the length of the first connecting frame 111 is greater than the length of the second connecting frame 112.

[0074] This arrangement places the two gaps on the long and short sides of the device, respectively, creating an asymmetrical gap distribution. Because the first connecting frame 111 is relatively long, it acts as the primary metal radiator, forming sufficiently long continuous metal segments on both sides of the first gap 201. These metal segments can serve as the main radiator for 5G mid-to-high frequency bands such as n77, n78, n79, or 4G mid-to-high frequency bands. Simultaneously, the second gap 202 is located on the second connecting frame 112, dividing the short-side metal segment into two parts. One part can serve as an auxiliary antenna radiator to support functions such as satellite positioning, WiFi, or SUB6G diversity. Its shorter length adapts to the wavelength requirements of high-frequency bands, avoiding efficiency degradation due to excessive radiator length. The first gap 201 and the second gap 202 are located on the frame in different directions, which avoids the enhanced radiation coupling that may be caused by the two gaps being concentrated on the same frame. It also reduces the local weakening of the metal structure strength caused by the concentration of gaps, so that the antenna function can be distributed in the metal area in different directions. The main antenna is concentrated on the long side radiator, and the diversity antenna or auxiliary antenna is arranged on the short side, forming spatial isolation.

[0075] In the third embodiment of this application, the device frame 110 includes two first connecting frames 111 and two second connecting frames 112, which are sequentially and alternately connected to form the device frame 110; a first gap 201 and a second gap 202 are respectively disposed on the two second connecting frames 112; wherein the length of the first connecting frame 111 is greater than the length of the second connecting frame 112.

[0076] In this way, a slit is set on each short frame, so that the two short metal segments are independently divided, forming two separate radiation regions. The first connecting frame 111 of the two long sides remains continuous without a slit. As a complete metal structure, it has good mechanical strength and electromagnetic shielding continuity, which can effectively suppress electromagnetic leakage from the internal circuit to the outside. The continuous long side structure can serve as the main radiator to carry the function of the 5G / 4G main antenna and improve the radiation efficiency of the antenna in the low frequency range. The two second connecting frames 112 are divided into two segments by the first gap 201 and the second gap 202. Each short metal segment becomes an independent local radiator, which can be used to arrange diversity antennas or auxiliary function antennas. This structure achieves the functional separation of the main antenna and diversity antenna while retaining only two slits. The main antenna relies on the continuous long side radiator to ensure efficient radiation in low and mid-high frequencies; the diversity and auxiliary antennas are undertaken by the two short side segments, achieving spatial isolation and frequency band adaptation.

[0077] In the first and second embodiments of this application, the device frame 110 includes two first connecting frames 111 and two second connecting frames 112, which are alternately connected to form the device frame 110. The length of the first connecting frame 111 is greater than the length of the second connecting frame 112. The plurality of antenna assemblies 40 include a first antenna assembly 400, a second antenna assembly 500, a third antenna assembly 330, a fourth antenna assembly 340, and a fifth antenna assembly 361. The first antenna assembly 400, the second antenna assembly 500, and the third antenna assembly 330 are all connected to one of the two first connecting frames 111. The fourth antenna assembly 340 and the fifth antenna assembly 361 are respectively connected to the two second connecting frames 112.

[0078] Thus, the first antenna assembly 400, the second antenna assembly 500, and the third antenna assembly 330 are all connected to one of the first connecting frames 111. The first connecting frame 111 serves as the main radiator, centrally carrying multiple communication functions. Because the first connecting frame 111 is relatively long, it has sufficient physical space to accommodate the feed points and tuning circuits of multiple antennas, supporting the distribution of antenna functions of different frequency bands on the same metal segment. Frequency band isolation and performance optimization are achieved through their independent feed points and tuning circuits. The fourth antenna assembly 340 and the fifth antenna assembly 361 are respectively connected to two second connecting frames 112. Because the second connecting frames 112 are relatively short, their structure is adapted to the needs of high-frequency band or auxiliary function antennas. The short-side antenna assembly is physically separated from the long-side main radiator in space, forming isolation in the vertical polarization direction and reducing the risk of cross-coupling.

[0079] In the third embodiment of this application, the device frame 110 includes: two first connecting frames 111 and two second connecting frames 112, which are alternately connected to form the device frame 110. The length of the first connecting frame 111 is greater than the length of the second connecting frame 112. One of the two first connecting frames 111 is connected to the fourth antenna assembly 340, the third antenna assembly 330, and the first antenna assembly 400. The second antenna assembly 500 and the fifth antenna assembly 361 are respectively connected to the two second connecting frames 112.

[0080] Thus, the fourth antenna assembly 340, the third antenna assembly 330, and the first antenna assembly 400 are all connected to one of the two first connecting frames 111. The first connecting frame 111 serves as the main radiator, centrally carrying multiple communication functions. Its relatively long physical length supports the resonance requirements of multi-band antennas, including 5G cellular main antennas, B21 / B32 / B11 bands, and SUB6G main antennas, as well as mid-to-high frequency diversity functions. Multiple antenna assemblies share the same metal radiator, achieving functional isolation through their independent feed points and tuning circuits. This optimizes the isolation between the main and diversity antennas, reduces co-band interference, and improves signal reception stability. The second antenna assembly 500 and the fifth antenna assembly 361 are respectively connected to the two second connecting frames 112, meaning only one antenna assembly is arranged in each short frame. The second connecting frame 112 is relatively short, structurally adaptable to high-frequency or auxiliary functions. The short-side antenna assemblies are physically separated from the long-side main radiator in space, forming isolation in the vertical polarization direction and reducing mutual coupling.

[0081] This application provides an optional embodiment in which the width range of the first gap 201 and the width range of the second gap 202 are both 1 mm to 2 mm.

[0082] In this embodiment, the gap width is controlled within the range of 1 to 2 mm, which ensures both the structural integrity and mechanical strength of the metal frame (avoiding stamping breakage) and sufficient capacitive coupling between the antenna radiator and the ground plane to achieve effective excitation in the low-frequency band (<1 GHz). This width range is compatible with injection molding filling processes (such as plastic brackets), allowing for an appearance design with the same color as the metal shell, improving the overall aesthetics. At the same time, the optimized gap size reduces RF loss, improves antenna efficiency, and enables the entire device to meet the radiation and SAR requirements of certifications such as FCC / CE / CCC (mandatory regulatory certifications in the three major global core markets: China's CCC, the United States' FCC, and the European Union's CE).

[0083] This application also includes a terminal device, such as... Figure 1 As shown, the device includes a device body 10 and an antenna module, with the antenna module mounted on the device body 10.

[0084] The device body 10 includes a printed circuit board 20, a first housing 120, a screen 30, and a cover plate 50. The screen 30 covers the first housing 120, and a first mounting space is provided between the screen 30 and the first housing 120. The printed circuit board 20 is disposed in the first mounting space and on the first housing 120. The cover plate 50 covers the side of the first housing 120 away from the screen 30. A second mounting space is provided between the cover plate 50 and the first housing 120. The sixth antenna assembly 710, the seventh antenna assembly 720, and the eighth antenna assembly 730 are located in the second mounting space.

[0085] This application solves the following technical problems of the prior art: With the rapid development of global communication technology, metal flat panel devices have become the mainstream cross-regional communication terminals. Their demand for full-band coverage of 5G, 4G, WiFi and satellite navigation is becoming increasingly urgent in order to meet the cross-regional usage needs of global users.

[0086] Current 5G metal flat panel antennas generally adopt a metal frame design with four or more slots. By creating multiple slots in the metal frame to construct a multi-antenna radiation structure, multi-band communication such as 5G NR, SUB-6G, 4G LTE, satellite navigation, and WiFi / Bluetooth can be achieved, meeting the basic communication performance requirements of 5G metal flat panels. Although multi-band communication can be achieved, there are many obvious defects when using stamped aluminum parts for production: complex production process, low yield, and high cost, which seriously restricts mass production; many metal slots in the body significantly affect the integrity of the body appearance; at the same time, unreasonable multi-antenna layout and insufficient isolation between antennas can easily lead to unstable communication signals.

[0087] To address the aforementioned technical deficiencies, this application proposes a metal-look ID flat panel and 5G antenna solution with only two slits. Utilizing an ultra-thin stamped aluminum material, it effectively controls production costs while meeting the communication performance standards and relevant regulatory certification requirements of operators. This solves the core challenges of existing technologies in simultaneously achieving multi-band coverage, simplified metal frame structure, production cost control, and communication stability. The 5G two-slit metal flat panel antenna solution and metal flat panel device provided by this invention can meet the communication performance standards and regulatory certification requirements of operators.

[0088] The purpose of this application is to provide a 5G 2-seam ID multi-band full-coverage metal flat panel antenna solution and flat panel device. By optimizing the antenna layout and setting up filtering and isolation circuits, it can achieve full-band coverage of 5G, 4G, WiFi and satellite navigation. At the same time, it can solve the isolation problem between multiple antennas in the same frequency band of 5G / 4G, improve communication stability, and achieve integrated integration of antenna and body structure to ensure the mechanical strength and appearance integrity of the body.

[0089] The following technical effects were achieved: 1. By adopting a two-slit metal appearance ID flat panel design, the metal frame structure is simplified, the complexity of the production process is effectively reduced, the production yield is improved, and the production cost is significantly reduced, solving the problems of complex production processes and high costs in the existing technology; 2. By rationally optimizing the antenna layout, multiple antennas are integrated into the metal frame, realizing the integration of the antenna and the fuselage structure, improving the antenna radiation efficiency, and ensuring the mechanical strength and appearance integrity of the fuselage. This solves the problems of unreasonable antenna layout and poor appearance integrity in the existing technology. 3. Dedicated filtering and isolation circuits are used, which are respectively arranged between the 5G / 4G main diversity antennas and between the antennas in the same frequency SUB6G band. This effectively solves the isolation problem between multiple antennas, reduces signal interference, and significantly improves communication stability and signal quality. 4. Through reasonable antenna layout design, full-band coverage of 5G, 4G, WiFi and satellite navigation is achieved, eliminating the need to design dedicated antennas for different areas, reducing production and manufacturing costs, and solving the problem of needing to design dedicated antennas for different areas in existing technologies; 5. By optimizing the antenna layout and structural design, multi-band antennas are efficiently integrated within a limited space, meeting the growing and diversified communication needs and overcoming the shortcomings of traditional antenna design schemes in terms of space utilization and communication performance.

[0090] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: By setting the first frame 200 and the second frame 300, and by only setting the first gap 201 and the second gap 202 on the device frame 110, the continuity of the metal body is improved, the structural strength of the body is greatly enhanced, and the problem of fragmented frame structure and poor bending and torsional resistance caused by the need for more than four gaps to isolate antennas in traditional equipment is avoided, thus significantly improving the appearance integrity. At least two antenna components are integrated into the same metal frame (first frame 200), and independent transmission and reception of the same frequency / near frequency antennas are achieved through a dedicated frequency band isolation circuit. Different antenna components do not interfere with each other when operating in the same frequency band, and no additional physical isolation or shielding layer is required, thus improving space utilization. With the first frame 200 as the main radiator, the conductivity is good and the surface area is large, and the radiation efficiency is significantly improved, solving the problem of excessive gaps in the terminal equipment in the prior art, which weakens the mechanical strength of the frame structure.
