Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0038] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0039] A three-band directional antenna includes a mounting base 1, four connectors 2, four high-frequency antenna modules 3, four combiners 4, and four low-frequency antenna modules 5;

[0040] The four connectors 2 are provided on the back of the mounting base plate 1, and the four combiners 4, the four high-frequency antenna modules 3, and the four low-frequency antenna modules 5 are provided on the front of the mounting base plate 1. One connector 2 is connected to one high-frequency antenna module 3 and one low-frequency antenna module 5 through one combiner 4.

[0041] The mounting base plate 1 is a rectangular plate structure, the four low-frequency antenna modules 5 are arranged in the middle of the mounting base plate 1, the four high-frequency antenna modules 3 are arranged at the four corners of the mounting base plate 1, and the four high-frequency antenna modules 3 are arranged on the outside of the four low-frequency antenna modules 5.

[0042] By placing the low-frequency antenna module 5 in the center of the mounting base 1 and the high-frequency antenna modules 3 at the four corners of the mounting base 1, the present invention achieves a compact structure while maintaining excellent electrical performance. This allows for the combined installation of antenna modules of different frequency bands on the limited mounting base 1. Furthermore, this design may help simplify the manufacturing process, thereby reducing costs.

[0043] By integrating four high-frequency antenna modules and four low-frequency antenna modules, adjusting the position and quantity of the high-frequency antenna module 3 and the low-frequency antenna module 5, and selecting a suitable combiner 4, the directional antenna of the utility model can support the operation of multiple frequency bands at the same time, significantly improving the electrical performance, and solving the problem that traditional directional antennas cannot cover a wider operating frequency band; the directional antenna can flexibly adapt to different application scenarios and frequency band requirements, improving the versatility and flexibility of the antenna.

[0044] Furthermore, the high-frequency antenna module 3 includes a first reflector 31, a first microstrip line 32 and six high-frequency oscillators 33;

[0045] The first reflector 31 is a rectangular plate structure. The six high-frequency oscillators 33 are arranged in an array at intervals along the length extension direction of the first reflector 31 . The six high-frequency oscillators 33 are connected by the first microstrip line 32 .

[0046] The combination of the first reflector 31, the first microstrip line 32 and the high-frequency vibrator 33 constitutes a relatively simple and easy-to-manufacture antenna module. This modular design not only simplifies the overall structure of the directional antenna, but also reduces the complexity and cost of the manufacturing process. By arranging six high-frequency vibrators 33 in an array-like manner along the length of the first reflector 31, the radiation energy in the high-frequency band can be more effectively concentrated and directed, thereby improving the gain and radiation efficiency of the antenna in the high-frequency band. The array-type design of the high-frequency vibrator 33 helps to achieve a more uniform frequency response in the high-frequency band, reduce frequency offset and distortion, and ensure the performance consistency of the antenna at different frequencies; using the first microstrip line 32 to connect the high-frequency vibrator 33 can reduce the volume and weight of the antenna while maintaining or improving the electrical performance compared to traditional coaxial cables or other connection methods.

[0047] Furthermore, the low-frequency antenna module 5 includes a second reflector, a second microstrip line 52 and six low-frequency oscillators 53;

[0048] The second reflector is a rectangular plate structure. The six low-frequency oscillators 53 are arranged in an array at intervals along the length extension direction of the second reflector. The six low-frequency oscillators 53 are connected by the second microstrip line 52.

[0049] By arranging six low-frequency oscillators 53 in an array along the length of the second reflector, the radiated energy in the low-frequency band can be more effectively concentrated and directed, thereby improving the antenna's gain and radiation efficiency in the low-frequency band. This design helps ensure stable performance and good coverage of the antenna in the low-frequency band.

[0050] Combined with the design of high-frequency antenna module 3, improvements to low-frequency antenna module 5 further enhance the antenna's multi-band compatibility. By optimizing the arrangement and connection of low-frequency and high-frequency oscillators, the antenna maintains excellent performance across different frequency bands, meeting the needs of a variety of application scenarios.

[0051] Furthermore, the two high-frequency antenna modules 3 are arranged vertically to form a high-frequency antenna module 30, and the two low-frequency antenna modules 5 are arranged horizontally to form a low-frequency antenna module 50;

[0052] The two low-frequency antenna modules 50 are symmetrically arranged on both sides of the vertical symmetry axis of the mounting base 1 , and the two high-frequency antenna modules 30 are symmetrically arranged on both sides of the vertical symmetry axis of the mounting base 1 and are located outside the low-frequency antenna modules 50 .

[0053] By arranging two high-frequency antenna modules 3 vertically to form a high-frequency antenna module 30, and arranging two low-frequency antenna modules 5 horizontally to form a low-frequency antenna module 50, the antenna's directivity and gain can be further optimized. This design helps ensure that the antenna has stronger radiation capability in a specific direction, thereby improving communication quality and coverage.

[0054] By symmetrically placing the low-frequency antenna module 50 and the high-frequency antenna module 30 on either side of the vertical axis of symmetry of the mounting base 1, with the high-frequency antenna module 30 positioned outside the low-frequency antenna module 50, the antenna's structural layout can be further optimized. This not only helps reduce the antenna's overall size and weight, but also improves its aesthetics and ease of installation. The symmetrical arrangement of the high-frequency antenna module 30 and the low-frequency antenna module 50 reduces performance variations in different directions, improving the antenna's overall stability and anti-interference capabilities. This design helps ensure the antenna maintains excellent performance in a variety of environments, reducing communication interruptions or degradation due to external interference.

[0055] This improved design further enhances the directional antenna's multi-band compatibility. By optimizing the arrangement and connection of the high-frequency antenna module 30 and the low-frequency antenna module 50, the antenna maintains stable performance and good coverage across different frequency bands, meeting the needs of a variety of application scenarios. This improvement demonstrates significant advantages in improving antenna directivity and gain, enhancing stability and anti-interference capabilities, optimizing structural layout, improving multi-band compatibility, reducing manufacturing costs, and increasing scalability and adaptability.

[0056] Furthermore, the two second reflectors of the same low-frequency antenna module 50 are an integral reflector 51 , the length of the reflector 51 is L2 , and the length of the first reflector 31 is L1 , wherein 2L1 ≤ L2 .

[0057] Integrating the second reflectors of the two low-frequency antenna modules 5 into a single, integrated reflector 51 can more effectively concentrate the radiated energy in the low-frequency band and reduce energy loss caused by the segmented reflectors. This design helps improve the antenna's gain and radiation efficiency in the low-frequency band, thereby optimizing low-frequency radiation performance. The integrated reflector reduces the structural complexity and instability associated with multiple independent reflectors. The integrated reflector design helps enhance the overall structural stability of the antenna and reduce performance degradation caused by structural looseness or deformation.

[0058] By setting the relationship between the length L2 of the reflector 51 and the length L1 of the first reflector 31 to 2L1≤L2, the space on the mounting base for the antenna module can be more efficiently utilized. This design helps optimize the overall layout of the antenna, reducing space waste, while ensuring appropriate spacing between the high-frequency and low-frequency antenna modules to reduce mutual interference. Integrating the reflector 51 and optimizing its length relationship with the first reflector 31 helps further enhance the multi-band compatibility of the directional antenna. By optimizing the arrangement and connection of the low-frequency antenna module 50 and the high-frequency antenna module 30, it is possible to ensure that the antenna maintains stable performance and good coverage across different frequency bands.

[0059] Furthermore, the first reflector 31 and the reflector 51 are mounted on the front of the mounting base 1 through support columns, and the first reflector 31 and the reflector 51 are arranged parallel to the mounting base 1;

[0060] The combiner 4 is installed on the front of the mounting base 1. Two combiners 4 are provided between one low-frequency antenna module 50 and the mounting base 1. The other two combiners 4 are provided between another low-frequency antenna module 50 and the mounting base 1. The positions of the two combiners 4 correspond to the positions of the upper and lower high-frequency antenna modules 3 of the high-frequency antenna module 30, respectively.

[0061] The positions of the four connectors 2 on the back side of the mounting base 1 correspond one to one with the positions of the four combiners 4 on the front side of the mounting base 1 .

[0062] First reflector 31 and reflector 51 are mounted parallel to the front of mounting base 1 and secured with support posts, making more efficient use of space and optimizing the overall antenna structure. This design helps reduce the size and weight of the antenna while ensuring appropriate spacing between components to minimize mutual interference.

[0063] Combiner 4 is mounted on the front of mounting base 1, corresponding to the positions of high-frequency antenna module 30 and low-frequency antenna module 50. This simplifies combiner installation and improves installation convenience. This design also helps ensure a stable and reliable connection between the combiner and antenna modules.

[0064] Aligning the four connectors 2 on the back of the mounting base 1 with the four combiners 4 on the front optimizes the signal transmission path and reduces signal loss. This design helps ensure the stability and clarity of the antenna's received and transmitted signals, improving communication quality.

[0065] By installing the first reflector 31 and reflector 51 parallel to the front of the mounting base 1 and optimizing the installation position and connection method of the combiner 4 and connector 2, the antenna structure layout is optimized, installation convenience is improved, the signal transmission path is optimized, overall performance is enhanced, reliability and stability are strengthened, and the degree of manufacturing automation is increased. These improvements further enhance the market competitiveness and application value of the tri-band directional antenna.

[0066] Furthermore, the distance from the low-frequency vibrator 53 to the front surface of the mounting base 1 is greater than the distance from the high-frequency vibrator 33 to the front surface of the mounting base 1 .

[0067] By adjusting the distance between the low-frequency oscillator 53 and the high-frequency oscillator 33 relative to the mounting base 1, the radiation performance of the antenna can be further optimized. The low-frequency oscillator is farther away from the mounting base, which can reduce the loss of low-frequency signals during propagation and improve the gain and radiation efficiency of the low-frequency band. The high-frequency oscillator is closer to the mounting base, which helps ensure the stability and clarity of high-frequency signals during transmission. Placing the low-frequency oscillator and the high-frequency oscillator at different heights can reduce signal interference between them. This design helps ensure that the antenna maintains clear signal quality and stable communication when receiving and transmitting signals.

[0068] Furthermore, a reflective strip 6 is also included;

[0069] The reflective strips 6 are disposed on the left and right sides of the high-frequency antenna module 30 , and the reflective strips 6 extend along the length direction of the high-frequency antenna module 30 .

[0070] The setting of the reflection strip 6 can guide the electromagnetic waves emitted by the high-frequency antenna module 30 to radiate in a specific direction, thereby enhancing the directivity of the antenna. This design helps to ensure that the antenna has a stronger radiation capability in the target direction, improving the communication quality and coverage range. Through the reflection effect of the reflection strip 6, some of the electromagnetic waves that may have been lost can be redirected back to the target direction, thereby increasing the gain of the high-frequency antenna. The increase in gain means that the antenna can more effectively utilize electromagnetic wave energy when receiving and transmitting signals, thereby improving communication efficiency. The setting of the reflection strip 6 can also reduce the impact of interference signals from other directions on the high-frequency antenna module 30 to a certain extent. By guiding the electromagnetic waves to radiate in a specific direction, the reflection strip 6 can reduce the interference signals from non-target directions from entering the antenna, thereby improving the antenna's anti-interference ability.

[0071] Furthermore, the high frequency vibrator 33 is a 5G vibrator and / or a 6G vibrator;

[0072] The low-frequency vibrator 53 is a 2.4G vibrator;

[0073] The combiner 4 is a one-to-two combiner.

[0074] High-frequency oscillator 33 uses a 5G oscillator and / or a 6G oscillator, meaning the antenna can support 5G and potentially future 6G communication frequency bands. This helps the antenna adapt to future communication technology developments and provide users with faster and more stable network connections. Furthermore, the corresponding frequencies of high-frequency oscillator 33 are 5150MHz-5850MHz and 5850MHz-7150MHz.

[0075] Low-frequency oscillator 53 uses a 2.4GHz oscillator to ensure the directional antenna performs well within the 2.4GHz frequency band. The 2.4GHz band is commonly used by many wireless network technologies (such as Wi-Fi and Bluetooth), so this design helps the antenna maintain stable communication quality in a variety of application scenarios. Furthermore, the corresponding frequency of low-frequency oscillator 53 is 2400MHz-2500MHz.

[0076] The use of a one-to-two combiner enables the antenna to process low-frequency (2.4GHz) and high-frequency (5G / 6G) signals simultaneously. This design helps to simplify the antenna structure and improve signal processing capabilities. Further explanation: combiner 4 includes an L end and an H end, corresponding to low-frequency and high-frequency channels, respectively. The L end can filter out high-frequency signals to ensure that 2.4GHz low-frequency signals pass through; the H end can filter out low-frequency signals to ensure that 5G / 6G high-frequency signals pass through. This design helps to reduce signal interference and improve signal transmission quality.

[0077] The antenna can simultaneously support multiple frequency bands, including 2.4GHz, 5G, and 6G, making it suitable for a variety of communication scenarios and devices. This helps enhance the antenna's adaptability and flexibility to meet users' diverse communication needs.

[0078] Furthermore, it also includes an antenna housing 7, which is detachably mounted on the front of the mounting base 1, and the antenna housing 7 covers the outside of the high-frequency antenna module 30 and the low-frequency antenna module 50.

[0079] The antenna housing 7 provides physical protection for the high-frequency antenna module 30 and the low-frequency antenna module 50 inside the antenna. On the one hand, it can prevent external objects from directly contacting the antenna components, reducing damage caused by physical factors such as collision and friction. On the other hand, it can resist the impact of harsh environments on the internal components of the antenna, such as dustproof, waterproof, moisture-proof, etc., thereby improving the service life and stability of the antenna outdoors or in harsh conditions.

[0080] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
