[0039] First Embodiment

[0040] See Figures 1-2 This application provides a vertically polarized multi-frequency antenna structure, the main structure of which includes a ground metal layer 1, a first radiating plate 2, a metal support portion 16, a metal bending portion 3, a metal extension portion 4, and a second radiating plate 5.

[0041] Among them, the grounding metal layer 1 is located at the bottom and extends horizontally. The metal grounding layer is used to provide a stable potential reference point for the antenna structure, thereby reducing unnecessary noise interference and improving the clarity of the antenna signal.

[0042] The first radiating plate 2 is located vertically above the grounded metal layer 1 and extends horizontally. A vertically penetrating tuning hole 6 is provided in the first radiating plate 2. The first radiating plate 2 can be responsible for converting electrical signals of the corresponding frequency band into electromagnetic waves for outward transmission. At the same time, it can also receive electromagnetic waves of the corresponding frequency band from the outside and convert them into electrical signals. The vertically penetrating tuning hole 6 in the first radiating plate 2 can adjust the operating frequency and impedance matching parameters of the first radiating plate 2.

[0043] The metal support 16 extends vertically between the grounded metal layer 1 and the first end side of the first radiating plate 2. Figure 2 In the above, the first end side of the ground metal layer 1 and the first radiating plate 2 refers to the side of the ground metal layer 1 and the first radiating plate 2 away from the center of the multi-frequency antenna structure. The bottom end and the top end of the metal support part 16 are fixedly connected to the center of the first end side of the ground metal layer 1 and the first radiating plate 2, respectively. That is, the metal support part 16 is arranged perpendicularly to the ground metal layer 1, and the first radiating plate 2 is further arranged perpendicularly to the metal support part 16.

[0044] The metal bending portion 3 extends vertically downward and is arranged on the second end side of the first radiating plate 2. Figure 2 In the context of the first radiating plate 2, the second end side refers to the side of the first radiating plate 2 that is close to the center of the multi-frequency antenna structure. The top end of the metal bending part 3 is fixedly connected to the center of the second end side of the first radiating plate 2, that is, the metal bending part 3 is arranged perpendicularly to the first radiating plate 2.

[0045] The metal extension 4 faces away from the first radiating plate 2 and extends horizontally at the bottom of the metal bending section 3. The first end of the metal extension 4 near the metal bending section 3 is fixedly connected to the bottom end of the metal bending section 3, that is, the metal extension 4 and the metal bending section 3 are arranged perpendicularly.

[0046] The second radiating plate 5 extends vertically upward and is arranged at the second end of the metal extension 4 away from the metal bending portion 3. The bottom end of the second radiating plate 5 is fixedly connected to the second end of the metal extension 4.

[0047] In summary, this embodiment provides a vertically polarized multi-frequency antenna structure. Through the structural design of the grounding metal layer 1, the first radiating plate 2, the metal bending portion 3, the metal extension portion 4, and the second radiating plate 5, the combination of the first radiating plate 2, the metal support portion 16, and the metal bending portion 3 is used to excite signal resonance for the first frequency band, and the second radiating plate 5 is used to excite signal resonance for the second frequency band. This enables the antenna structure to meet the multi-frequency signal coverage requirements, is suitable for the connection needs of devices in various scenarios, effectively reduces co-channel interference, and, by adopting vertical polarization, optimizes electromagnetic wave propagation efficiency, adapts to signal transmission needs in complex indoor and outdoor environments, and achieves 360° omnidirectional coverage in the horizontal direction with uniform signal distribution, effectively improving the signal connection stability of terminal devices.

[0048] The following will provide a more detailed description of the specific structure and function of the vertically polarized multi-frequency antenna structure provided in this embodiment:

[0049] Preferably, in one embodiment, the first radiating plate 2 includes at least a set of symmetrically arranged first radiating arms 7 and second radiating arms 8, the first radiating arms 7 and the second radiating arms 8 having a rectangular structure, and each of the first radiating arms 7 and the second radiating arms 8 having a corresponding tuning hole 6.

[0050] In this embodiment, the symmetrical arrangement of the first radiating arm 7 and the second radiating arm 8 helps to maintain the symmetry of the antenna structure, reduce the radiation pattern distortion caused by asymmetry, and make the signal transmission more stable and reliable. At the same time, it can effectively adjust the input impedance and bandwidth of the first radiating plate 2 to better suit the target operating frequency range.

[0051] Preferably, in one embodiment, the width of the second radiating plate 5 extends gradually from the bottom end of the second radiating plate 5 toward the top end along the height extension direction of the second radiating plate 5, that is, the second radiating plate 5 has an inverted triangular structure. The special structural design of the second radiating plate 5 helps to adjust the frequency response characteristics of the second radiating plate 5 for the second frequency band, optimize the frequency response and bandwidth of the second radiating plate 5, and improve the directivity and gain of the second radiating plate 5.

[0052] Preferably, in one embodiment, a coaxial cable is provided, with an inner conductor inside the coaxial cable. The inner conductor is surrounded by a metal shielding layer, and a non-conductive dielectric layer isolates the inner conductor from the metal shielding layer. The inner conductor transmits electrical signals, and the metal shielding layer prevents external electromagnetic interference from affecting the internal signal, while also preventing the internal signal from interfering with the external environment. In this embodiment, the inner conductor of the coaxial cable is electrically connected to the feed point 9 at the bottom of the second radiating plate 5, and the metal shielding layer of the coaxial cable is electrically connected to the grounded metal layer 1, thereby realizing the signal transmission and isolation functions of the multi-frequency antenna structure.

[0053] Preferably, in one embodiment, the grounding metal layer 1 is provided with a plurality of positioning through holes 10 and fixing through holes 11, and the antenna PCB connecting board is provided with positioning pins. The positioning through holes 10 are adapted to the positioning pins in the antenna PCB connecting board. By making the positioning through holes 10 and the positioning pins fit together, the relative fixed position of the multi-frequency antenna structure and the antenna PCB connecting board during assembly can be quickly determined.

[0054] The fixing through hole 11 is adapted to the mounting hole of the antenna PCB connection board, and the fixing through hole 11 and the mounting hole of the antenna PCB connection board can be fixedly connected to the multi-frequency antenna structure and the antenna PCB connection board by passing through the fastener 12. The fastener 12 includes fastening elements such as bolt assemblies, rivets, and screws.

[0055] Preferably, in one embodiment, the grounding metal layer 1 is provided with a mounting groove 13, and clamps 14 are provided on both sides of the mounting groove 13. The mounting groove 13 is used to place the foam module 15, and the clamps 14 are used to clamp and fix the foam module 15.

[0056] When a foam module 15 is fixedly installed in the grounding metal layer 1, the top surface of the foam module 15 abuts against the bottom surface of the metal extension 4. The foam module 15 has high elasticity and can effectively absorb external vibration and impact, improve the durability of the antenna in outdoor or mobile scenarios, and at the same time maintain the attitude stability of the metal bending part 3, the metal extension 4 and the second radiating sheet 5, thereby reducing the risk of signal interference and ensuring the stability of communication quality.

[0057] Preferably, in one embodiment, the grounding metal layer 1, the metal support portion 16, the first radiating plate 2, the metal bending portion 3, the metal extension portion 4, and the second radiating plate 5 are integrally formed by stamping. By completing the forming process of the multi-frequency antenna structure in one go, the time and steps required to manufacture each component individually are reduced, which greatly improves the production efficiency of the multi-frequency antenna structure, reduces manufacturing costs, and makes the overall structure of the multi-frequency antenna more robust and durable, providing better protection when facing harsh environments such as external impacts and vibrations, and has excellent structural strength and stability.

[0058] Preferably, in one embodiment, the grounding metal layer 1 is defined as having a rectangular structure, with the long side of the grounding metal layer 1 being 27.20 mm and the short side of the grounding metal layer 1 being 18.70 mm.

[0059] The long side of the first radiating plate 2 is defined as 26.20 mm, and the short side of the first radiating plate 2 is defined as 9.00 mm;

[0060] The height of the metal support 16 is limited to 12.20 mm;

[0061] The height of the metal bend 3 is limited to 10.70 mm;

[0062] The length of the metal extension 4 is defined as 4.70 mm;

[0063] The height of the second radiating plate 5 is limited to 10.61 mm.

[0064] By limiting the dimensions of each component in the multi-frequency antenna structure, the combination of the first radiating plate 2, the metal support part 16 and the metal bending part 3 can be used to excite signal resonance for the 2.4GHz frequency band, and the second radiating plate 5 can be used to excite signal resonance for the 5GHz and 6GHz frequency bands.

[0065] In summary, this embodiment provides a vertically polarized multi-frequency antenna structure. The multi-frequency antenna structure includes a grounded metal layer 1, a first radiating plate 2, a metal support portion 16, a metal bending portion 3, a metal extension portion 4, and a second radiating plate 5. These components combine to form a unique antenna arrangement. The combination of the first radiating plate 2, the metal support portion 16, and the metal bending portion 3 is used to excite signal resonance for the 2.4GHz frequency band, while the second radiating plate 5 is used to excite signal resonance for the 5GHz and 6GHz frequency bands. This enables the antenna structure to perform multi-frequency signal reception and transmission, meeting the connection needs of devices in various scenarios and effectively reducing co-channel interference. Furthermore, the multi-frequency antenna structure employs vertical polarization, which effectively optimizes electromagnetic wave propagation efficiency, adapts to signal transmission requirements in complex indoor and outdoor environments, and possesses excellent horizontal omnidirectional characteristics, achieving 360° omnidirectional coverage in the horizontal direction with uniform signal distribution, effectively improving the connection stability of terminal devices.

The multi-frequency antenna structure is compact, has high mechanical strength, and is small in size, making it easy to integrate into various terminal devices (such as routers, IoT devices, etc.). This saves antenna placement space and can significantly reduce production costs, achieving a balance between high performance and low cost.
