[0037] In the description of the utility model, it needs to be explained that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between the two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0038] A directional array antenna comprises a mounting plate 1, a first frequency band radiating unit 2, a second frequency band radiating unit 3 and a third frequency band radiating unit 4.

[0039] A GPS receiving unit 5 is mounted above the mounting plate 1, the GPS receiving unit 5 is electrically connected with the radiating unit, and the GPS receiving unit 5 is used for receiving satellite signals.

[0040] A plurality of mounting grooves 11 parallel to each other and arranged along the left and right directions are formed on the surface of the mounting plate 1, and the mounting grooves 11 are arranged in the up and down directions.

[0041] The two mounting grooves 11 on both sides have a single mounting position respectively, and the mounting grooves 11 in the middle have two mounting positions arranged in the up and down directions respectively.

[0042] A pair of the first frequency band radiating units 2, a pair of the second frequency band radiating units 3 and a pair of the third frequency band radiating units 4 are installed in the installation positions in sequence and staggered obliquely.

[0043] As shown in the figure, the directional array antenna is mainly composed of an installation plate 1, first frequency band radiating units 2, second frequency band radiating units 3 and third frequency band radiating units 4, wherein these radiating units are arranged on the installation plate 1 to form directional signal receiving and transmitting capabilities. Figures 1-3

[0044] Above the installation plate 1, a GPS receiving unit 5 is installed, which establishes an electrical connection with each radiating unit. When satellite signals come from the sky, the GPS receiving unit 5 will receive or each frequency band radiating unit will capture these satellite signals, process these signals from different frequency bands by the GPS receiving unit 5, and extract useful positioning information, and then radiate them out through each frequency band radiating unit.

[0045] Further, the surface of the installation plate 1 is designed with installation grooves 11 arranged in parallel and along the left and right directions, and the installation grooves 11 are all arranged in the up and down directions, providing a basic guide for the installation of the radiating units. Each of the installation grooves 11 on both sides has one installation position, and the installation groove 11 in the middle is provided with two installation positions arranged in the up and down directions. The radiating units of each frequency band are compactly arranged in the adjacent installation grooves 11 and installation positions, so that the antenna can more flexibly configure the radiating units of different frequency bands, and at the same time, can maximize the use of space to receive and process signals.

[0046] In particular, a pair of first frequency band radiating units 2, a pair of second frequency band radiating units 3 and a pair of third frequency band radiating units 4 are installed in the installation positions in sequence and staggered obliquely. Specifically, a pair of first frequency band radiating units 2, a pair of second frequency band radiating units 3 and a pair of third frequency band radiating units 4 are installed in the installation positions in sequence according to the order of the installation grooves 11 from left to right and from top to bottom. Through the above layout, the two groups of radiating units of each frequency band do not share the same installation groove 11. Such a layout ensures the physical isolation between the radiating units of each frequency band, reducing mutual interference. Since the radiating units of each frequency band are designed to receive or transmit signals within a specific frequency range. When the antenna is working, signals of different frequency bands will be captured or transmitted by the corresponding radiating units. Since these radiating units are physically separated, they can more effectively process their respective frequency band signals without interference from other frequency band signals.

[0047] The installation groove 11 in the middle is designed to install radiating units of two different radiating frequencies. This configuration allows the antenna to simultaneously receive and process signals from different frequency bands in the same space, thereby enhancing the versatility and flexibility of the antenna.​

[0048] Therefore, the beneficial effects of the present application are as follows:

[0049] 1. Comprehensive frequency band coverage: By integrating radiation units of different frequency bands, the antenna can achieve comprehensive coverage of multiple frequency bands, meeting different communication and positioning needs.

[0050] 2. Stable signal reception: Since the radiation units of each frequency band are arranged on the mounting plate 1 and integrated by the GPS receiving unit 5, the antenna can provide more stable and accurate signal reception capability.

[0051] 3. High space utilization: The design of parallel and vertically arranged mounting grooves 11 on the mounting plate 1, as well as the double mounting position configuration of the middle mounting groove 11, allows the antenna to maximize space utilization while maintaining a compact structure.

[0052] 4. Flexible configuration: Due to the diagonal and staggered installation of units of different frequency bands, the antenna can be flexibly configured according to the needs of different application scenarios, improving the adaptability and scalability of the antenna.

[0053] In summary, the directional array antenna has significant advantages in frequency band coverage, signal reception stability, space utilization, and configuration flexibility, providing a new solution for the development of wireless communication and positioning technology.

[0054] Further explanation, the second frequency band radiation unit 3 includes a second power amplifier plate 31 and two groups of second radiation dipoles 32;

[0055] The second power amplifier plate 31 is installed on the mounting position, and two groups of second radiation dipoles 32 are installed on the second power amplifier plate 31 in a vertical direction in a linear form. The second power amplifier plate 31 is provided with a second feed network 33, and the second feed network 33 is electrically connected with the two groups of second radiation dipoles 32.

[0056] The second radiation dipole 32 includes a second vertical polarization dipole 321 and a second horizontal polarization dipole 322, and the second vertical polarization dipole 321 and the second horizontal polarization dipole 322 are arranged perpendicular to each other.

[0057] Specifically, as shown in Figure 2 The second frequency band radiation unit 3 mainly consists of a second power amplifier plate 31 and two groups of second radiation dipoles 32, which are used to transmit and receive radio signals within a specific frequency band. In an optional embodiment, the radiation frequency band of the second frequency band radiation unit 3 is 5150-5850MHz.

[0058] The second power amplifier board 31 is the control and power amplification core of the entire radiation unit. It is responsible for receiving satellite signals from the GPS receiving unit 5, processing the signals through internal circuits, and amplifying the signals to a sufficient power level to drive the second radiation oscillator 32 for signal transmission. At the same time, the second power amplifier board 31 is also responsible for receiving receiving signals from the second radiation oscillator 32, performing preliminary signal processing and amplification, and then transmitting them to the GPS receiving unit 5 for processing.

[0059] The second radiation oscillator 32 is the component that actually transmits and receives signals. Two groups of second radiation oscillators 32 are used, each group including a second vertical polarization oscillator 321 and a second horizontal polarization oscillator 322, which are arranged perpendicular to each other to achieve vertical and horizontal polarization transmission and reception of signals. The second vertical polarization oscillator 321 is mainly responsible for the transmission and reception of vertically polarized signals, while the second horizontal polarization oscillator 322 is responsible for the transmission and reception of horizontally polarized signals. This design enables the third frequency band radiation unit 3 to handle more diverse signals, improving flexibility and coverage.

[0060] The second feed network 33 is a key component that connects the second power amplifier board 31 and the second radiation oscillator 32. It is responsible for efficiently transmitting the signal power output by the second power amplifier board 31 to the second radiation oscillator 32, while ensuring that the phase and amplitude of the signal remain consistent to achieve optimal transmission and reception effects. The second feed network 33 is also responsible for transmitting signals received by the second radiation oscillator 32 back to the second power amplifier board 31 for further processing.

[0061] Further explanation, the second power amplifier board 31 of the second frequency band radiation unit 3 located below is inclinedly arranged in the mounting position, and the inclined arrangement is that the second power amplifier board 31 gradually approaches the mounting plate 1 from top to bottom;

[0062] The second power amplifier board 31 of the second frequency band radiation unit 3 located above is arranged in parallel in the mounting position.

[0063] Specifically, as shown in Figure 3 The two groups of second radiation oscillators 32 have different installation attitudes: the second power amplifier board 31 located below is arranged obliquely, specifically gradually approaching the mounting plate 1 from top to bottom; and the second power amplifier board 31 located above is arranged in parallel.

[0064] By setting a downward angle for the second power amplifier board 31 located below, the reflection and scattering of signals on the ground can be effectively reduced, thereby reducing the multipath effect. The multipath effect refers to the phase difference and amplitude difference produced when signals pass through different paths to reach the receiving end, which can cause signal distortion and interference. At the same time, the setting of the downward angle also helps to reduce co-frequency interference, as the inclined signal transmission direction reduces direct interaction with other co-frequency signal sources.

[0065] The second power amplifier board 31 located above is arranged in parallel, which means that the transmission and reception directions of its second radiating element 32 are horizontal, in order to supplement the signal coverage of the radiating unit located below, or to provide additional signal directionality in certain situations.

[0066] To further explain, the second power amplifier board 31 located below is tilted at an angle α of 7°.

[0067] like Figure 3 As shown, when the second signal is emitted at a certain downward tilt angle, the lower second-band radiation unit 3 can more effectively cover the target area while reducing the interference of ground-reflected signals on the original signal, thereby reducing multipath effects. In a preferred embodiment, the lower second power amplifier board 31 is tilted at an angle α of 7°.

[0068] To further explain, the first frequency band radiating unit 2 includes a first power amplifier board 21 and three sets of first radiating elements 22;

[0069] The first power amplifier board 21 is arranged in parallel at the mounting position. Three sets of the first radiating elements 22 are installed in a straight line along the vertical direction on the first power amplifier board 21. The first power amplifier board 21 is provided with a first power supply network 23. The first power supply network 23 is electrically connected to the three sets of the first radiating elements 22. The first power amplifier board 21 is used to distribute the power of the three sets of the first radiating elements 22.

[0070] The first radiating oscillator 22 includes a first vertically polarized oscillator 221 and a first horizontally polarized oscillator 222, which are arranged perpendicularly to each other.

[0071] Specifically, such as Figure 2 As shown, the first frequency band radiating unit 2 mainly consists of a first power amplifier board 21 and three sets of first radiating elements 22, used to transmit and receive signals within a specific frequency band. In an optional embodiment, the radiation frequency band of the first frequency band radiating unit 2 is 5925-6425MHz.

[0072] The first power amplifier board 21, positioned parallel to the mounting location, is a key component for signal amplification. It receives the modulated signal from the GPS receiver unit 5 and amplifies it to a sufficient power level for radiation through the antenna. Furthermore, the first power amplifier board 21 houses a first feed network 23, which is responsible for evenly distributing the amplified signal power to the three sets of first radiating elements 22. The design of the first feed network 23 ensures phase and amplitude consistency of the signal, which is crucial for directional radiation and reducing signal distortion.

[0073] Further, the three groups of first radiation dipoles 22 are installed in a linear manner along the up-down direction on the first power amplifier board 21. These dipoles are the components that actually radiate and receive signals. They convert the electrical signals output by the first power amplifier board 21 into electromagnetic waves and radiate them into space. Each group of first radiation dipoles 22 includes a first vertically polarized dipole 221 and a first horizontally polarized dipole 222, which are arranged perpendicular to each other. This dual-polarization design enables the first frequency band radiating unit 2 to handle both vertically polarized and horizontally polarized signals simultaneously, improving the capacity and flexibility of the antenna.

[0074] Further, the third frequency band radiating unit 4 includes a third power amplifier board 41 and three groups of third radiation dipoles 42.

[0075] The third power amplifier board 41 is arranged in parallel to the mounting position. The three groups of third radiation dipoles 42 are installed in a linear manner along the up-down direction on the third power amplifier board 41. The third power amplifier board 41 is provided with a third feed network 43, which is electrically connected to the three groups of third radiation dipoles 42. The third power amplifier board 41 is used to distribute power to the three groups of third radiation dipoles 42.

[0076] The third radiation dipoles 42 include a third vertically polarized dipole 421 and a third horizontally polarized dipole 422, which are arranged perpendicular to each other.

[0077] Specifically, as shown in Figure 2 The third frequency band radiating unit 4 is mainly composed of a third power amplifier board 41 and three groups of third radiation dipoles 42, which are used to transmit and receive signals within a specific third frequency band. In an optional embodiment, the radiation frequency band of the third frequency band radiating unit 4 is 6525-7125 MHz.

[0078] The third power amplifier board 41, as a power amplifier circuit board, is arranged in parallel to the mounting position. Its main function is to amplify signal power so that the signal can be transmitted further or drive a larger load. The third power amplifier board 41 receives the modulated signal from the GPS receiving unit 5 and amplifies it to an appropriate power level. The amplified signal is transmitted to the three groups of third radiation dipoles 42 through the third feed network 43. The third feed network 43 is a connecting bridge between the third power amplifier board 41 and the third radiation dipoles 42. It is responsible for evenly distributing the amplified signal power to the three groups of third radiation dipoles 42, ensuring that each dipole can receive sufficient power for radiation.

[0079] Three sets of third radiating elements 42 are mounted in a straight line along the vertical direction on the third power amplifier board 41. These elements are responsible for converting electrical signals into electromagnetic waves and radiating them into space. Each set of third radiating elements 42 includes a third vertically polarized element 421 and a third horizontally polarized element 422, which are arranged perpendicularly to each other. This design allows the third-band radiating element 4 to process both vertically and horizontally polarized signals simultaneously, improving the antenna's capacity and flexibility.

[0080] To further explain, protrusions 12 are provided on both sides of the mounting groove 11.

[0081] like Figure 1 As shown, in order to optimize wireless performance, especially to reduce interference between radiating units of different radiation frequency bands, a mounting groove 11 with a specific structure and protrusions 12 on both sides are designed in the mounting structure.

[0082] The mounting groove 11 is a structural part in wireless communication equipment used to install and fix radiating units of different radiation frequency bands. It is designed with a certain depth and width to accommodate the physical size and installation requirements of the radiating units. The protrusions 12 are located on both sides of the mounting groove 11, and their main function is to act as physical barriers to reduce or block direct signal interaction between radiating units from different radiation frequency bands. Such interaction may cause signal interference and affect the overall performance of the wireless communication.

[0083] To further explain, support plates 13 are provided on both sides of the mounting plate 1 extending outward.

[0084] like Figure 1 As shown, the mounting plate 1 is the main structural component supporting multiple sets of radiating units. The support plate 13 extends outwards from both sides of the mounting plate 1. It is designed with sufficient strength and rigidity to bear the weight of the mounting plate 1 and its structure, and also significantly increases the contact area between the mounting plate 1 and the external structure, thereby improving installation stability. This helps prevent loosening or damage caused by vibration or external forces during installation and use.
