Description

Technical Field

[0001] This invention relates to the technical field of drone jamming antennas, and in particular to an omnidirectional multi-band drone jamming antenna. Background Technology

[0002] To combat illegal drone flights and protect our targets, it is necessary to interfere with illegally flying drones, causing them to crash or be captured. Existing technologies disclose various drone jamming antennas. For example, Chinese invention patent CN118431733B proposes an antenna system and a drone jamming gun for a drone jamming gun. This drone jamming gun's antenna system is arranged in a layered configuration of a top, middle, and bottom layer. The structure includes an omnidirectional detection antenna, a detection antenna assembly, a jamming antenna assembly, and a navigation decoy antenna. The detection antenna assembly includes a first detection antenna and a second detection antenna. The jamming antenna assembly includes a first jamming antenna, a second jamming antenna, a third jamming antenna, and a fourth jamming antenna. The first detection antenna, the navigation decoy antenna, and the third jamming antenna are sequentially and alternately arranged on the top layer. The second detection antenna and the fourth jamming antenna share an antenna arrangement on the middle layer. The first and second jamming antennas are arranged coplanarly on the bottom layer. The omnidirectional detection antenna is located in the front area of ​​the top and middle layers. This system can achieve direction finding, attack, and decoy targeting of drones within the 300-6000MHz frequency band, and is compact, small in size, and easy to carry.

[0003] However, the aforementioned jamming antennas only interfere with the drones and not with the drone's ground control terminal. This means that after the drone is interfered with, the ground control terminal can use anti-jamming techniques to salvage the drone, resulting in a decrease in jamming effectiveness. Moreover, the aforementioned jamming antenna system transmits jamming signals in all directions in space, which consumes a lot of energy and can cause false interference to normal equipment, resulting in poor accuracy. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an omnidirectional multi-band UAV jamming antenna capable of simultaneously performing directional jamming on both UAVs and ground control terminals, thereby improving jamming effectiveness, reducing energy consumption, and enhancing accuracy.

[0005] This invention discloses an omnidirectional multi-band UAV jamming antenna, comprising a main unit chassis and a mounting plate, the mounting plate being mounted on the main unit chassis; it also includes multiple columns, multiple receiving antennas, multiple servo motors, multiple transmitting antennas, multiple servo motors, and multiple transmitting antennas. The multiple columns are vertically mounted on the mounting plate in a matrix arrangement. Multiple receiving antennas are evenly mounted circumferentially on the outer walls of each column. Multiple servo motors are respectively mounted on the tops of the multiple columns. Multiple transmitting antennas are respectively mounted on the output shafts of the multiple servo motors, and are concentrically arranged with the multiple columns. Multiple servo motors are respectively mounted on the multiple transmitting antennas. At the top of line one, multiple transmitting antennas are mounted on the output shafts of multiple servo motors. Three columns are arranged in an equilateral triangle, each equipped with thirty-six receiving antennas. Each of the thirty-six receiving antennas receives signals from a specific direction. During operation, the multiple receiving antennas receive signals emitted by the UAV and signals emitted from the UAV's ground station. Based on the strength of the received signals, each receiving antenna generates an electrical signal of varying strength. Simultaneously, the controller in the main unit selects the strongest electrical signal. The three receiving antennas, one generating the strongest electrical signal and the other generating the strongest electrical signal, are all pointed towards the drone. The three receiving antennas generating the strongest electrical signal (signal one) are all pointed towards the drone's ground end. Three servo motors drive the three transmitting antennas (signal one) to rotate, aligning their transmission directions with the three receiving antennas generating the strongest electrical signal (signal one). The three transmitting antennas emit interfering electromagnetic waves to interfere with the drone, and the drone is positioned within the intersection area of ​​these interfering electromagnetic waves, enhancing the interference effect. Simultaneously, the three servo motors (signal two) drive the three transmitting antennas to rotate. The second transmitting antenna rotates so that the transmission directions of the three second transmitting antennas are aligned with the three receiving antennas that generate the strongest electrical signal. The three second transmitting antennas emit interfering electromagnetic wave signals to interfere with the UAV's ground end. The UAV's ground end is located in the intersection area of ​​the interfering electromagnetic wave signals of the three second transmitting antennas, which enhances the interference effect on the UAV's ground end. Compared with the existing technology, it interferes with both the UAV and the ground control end at the same time, improves the interference effect, and has a directional function, concentrating the transmission of interference signals in the direction of the UAV and the direction of the ground control end, reducing energy consumption, improving the interference effect, reducing false interference to normal equipment, and improving accuracy.

[0006] Preferably, the main unit includes a signal amplifier, a clock module, an analysis module, a storage module, a ground positioning module, and a UAV damage module. The signal amplifier amplifies the signals received by multiple receiving antennas. The clock module modifies the timestamp of the amplified signal, which is then transmitted through multiple transmitting antennas (one and two). The analysis module analyzes the received signal information and categorizes the signals. The storage module stores the categorized signals. The ground positioning module locates the position of the ground terminal. The UAV damage module damages the UAV. After receiving signals from the UAV and the ground terminal, the signal amplifier amplifies the signals, and the clock module... The block modifies the timestamp of the amplified signal to generate a repeating strong signal of the same type as the signal emitted by the UAV and the ground terminal. These strong signals will block the communication channel between the UAV and the ground terminal, increase the amount of signals that the processors of the UAV and the ground terminal have to process, causing the processors to overload and lag, or insert interference signals into the command list of the UAV, causing the UAV to execute incorrect commands, thereby interfering with the UAV and the ground terminal. The interference signal will switch at any time according to the frequency hopping of the signals received by multiple receiving antennas, realizing full-band and all-round interference. The ground terminal positioning module locates the position of the ground terminal, thereby countering the ground terminal. The UAV damage module physically damages the UAV to ensure the stability of the interference effect.

[0007] Preferably, it also includes multiple fixed electrodes and multiple moving electrodes. Multiple fixed electrodes are evenly installed on the upper end of multiple columns, and the multiple fixed electrodes are respectively aligned with multiple receiving antennas. Multiple moving electrodes are respectively installed on the lower end of multiple transmitting antennas, and the multiple moving electrodes are respectively located in the transmission direction of multiple transmitting antennas, and the multiple moving electrodes are respectively aligned with multiple fixed electrodes. The analysis module of the main unit will highlight the multiple fixed electrodes that are aligned with the multiple receiving antennas that generate the strongest electrical signal. When multiple servo motors drive multiple transmitting antennas to rotate, the multiple transmitting antennas drive multiple moving electrodes to rotate synchronously. When the multiple moving electrodes are respectively aligned with the multiple marked fixed electrodes, the multiple servo motors stop rotating. At this time, the transmission direction of the multiple transmitting antennas is all facing the direction of the UAV, thereby improving the sensitivity of the multiple transmitting antennas.

[0008] Preferably, it also includes multiple brackets and multiple moving electrodes II. The upper ends of the multiple brackets are respectively connected to multiple transmitting antennas II, and the lower ends of the multiple brackets are all equipped with moving electrodes II. The multiple moving electrodes II are respectively aligned with multiple fixed electrodes. The multiple moving electrodes II are located outside the multiple fixed electrodes to avoid collision with the moving electrodes I. The analysis module of the main unit will highlight the multiple fixed electrodes that are aligned with the multiple receiving antennas that generate the strongest electrical signal II. When the multiple servo motors II drive the multiple transmitting antennas II to rotate, the multiple transmitting antennas II will drive the multiple brackets and moving electrodes II to rotate synchronously. When the multiple moving electrodes II are aligned with the multiple marked fixed electrodes, the multiple servo motors II stop rotating. At this time, the transmission direction of the multiple transmitting antennas II is all towards the ground end of the UAV, improving the sensitivity of the multiple transmitting antennas II.

[0009] Preferably, the ground-end positioning module is installed in the main unit chassis. This module is used to determine the geographical location of the ground unit. It includes a self-localization unit, a marker model unit, a fitting unit, a reading unit, and a navigation map unit. The self-localization unit determines the geographical location of the main unit chassis. The navigation map module understands the surrounding geographical environment of the main unit chassis and, in conjunction with the self-localization unit, positions the main unit chassis on the map. The marker model unit contains a built-in positioning model. This positioning model numbers multiple pillars and multiple receiving antennas, and divides the area around the main unit chassis into several positioning grids, which are based on the pillars. The antennas are labeled with their numbers. The fitting unit fits several positioning grids of the labeled model unit to the map, thus corresponding each positioning grid to a geographical location on the map. The reading unit reads the numbers of multiple receiving antennas facing the UAV and multiple receiving antennas on multiple pillars facing the UAV on the ground, and determines the corresponding positioning grid number. The determined positioning grid is the probabilistic location on the ground. The specific construction method of the positioning model is as follows: three pillars are set up, and thirty-six receiving antennas are set on the pillars. The three pillars are labeled A, B, and C, and the thirty-six receiving antennas on A are labeled a1, a2, a3, and a4 respectively. a2, a3...a36, a1, a2, a3...a36 divide the space around A into thirty-six sectors, labeled A1, A2, A3...A36 respectively; the thirty-six receiving antennas on B are labeled b1, b2, b3...b36, b1, b2, b3...b36 divide the space around B into thirty-six sectors, labeled B1, B2, B3...B36 respectively; the thirty-six receiving antennas on C are labeled c1, c2, c3...c36, c1, c2, c3...c36 divide the space around C into thirty-six sectors, labeled C1...c36 respectively. Let Ax be any one of A1, A2, A3...A36; By be any one of B1, B2, B3...B36; Cz be any one of C1, C2, C3...C36. Mark the area where Ax and By intersect (the secondary positioning grid) as AxBy; mark the area where Ax and Cz intersect (the secondary positioning grid) as AxCz; mark the area where By and Cz intersect (the secondary positioning grid) as ByCz; mark the area where Ax, By, and Cz intersect (the primary positioning grid) as AxByCz. The primary positioning grid represents the high-probability location on the ground, and the secondary positioning grid represents the probability location on the ground.

[0010] The fitting unit locates the main unit in the map provided by the navigation map unit based on the positioning information from the self-localization unit, and fits the positioning model onto the navigation map with the main unit as the center. The reading unit reads the numbers Ax, By, and Cz of the receiving antennas facing the ground on the three pillars A, B, and C, thereby determining the number of the main positioning cell AxByCz, and the numbers of the secondary positioning cells AxBy, AxCz, and ByCz. The specific location areas of the corresponding main positioning cell AxByCz and the secondary positioning cells AxBy, AxCz, and ByCz are obtained in the navigation map to complete the probabilistic positioning of the UAV on the ground. The method is simple and improves the positioning speed by using pre-marking.

[0011] Preferably, it also includes a communication module, which is installed on the main unit and is connected to the ground positioning module. The communication module is used to send the location data of the UAV ground terminal obtained by the ground positioning module. The communication module sends the obtained location information of the UAV ground terminal to the countermeasure unit. The countermeasure unit first countermeasures the high-probability location. If the UAV ground terminal signal does not disappear, it countermeasures the probability location and expands the countermeasure range with the high-probability location as the center until the UAV ground terminal signal disappears, thus completely eliminating the harm of illegal UAVs.

[0012] Preferably, it also includes a radar mount and multiple radar modules. The radar mount is installed in the middle of the mounting plate, and multiple radar modules are installed on the radar mount. The radar modules can be lidar, phased array radar, etc. By installing the radar mount and radar modules, the UAV can be detected at a long distance, the UAV can be detected earlier, and multiple transmitting antennas can be guided to interfere, thereby improving accuracy.

[0013] Preferably, it also includes a center column, push rods, lower support arms, upper support arms, ball joints, and ball seats. Three push rods, three lower support arms, three upper support arms, three ball joints, and three ball seats are provided. The center column is installed in the middle of the main unit housing. The three push rods are evenly arranged around the circumference of the center column. The inner ends of the three push rods are rotatably connected to the center column, and the outer ends of the three push rods are rotatably connected to multiple hinge shafts. The lower ends of the multiple lower support arms are rotatably mounted on the main unit housing, and the upper ends of the three lower support arms are rotatably connected to multiple hinge shafts. The lower ends of the three upper support arms are rotatably connected to three hinge shafts. Ball-head rods are installed at the upper ends of the three upper arms, and the three ball-head rods are movably connected to the three ball seats. The three ball seats are evenly installed on the lower end surface of the mounting plate. The three push rods extend and retract, so that the three push rods push the three lower arms and three upper arms vertically through the three hinge shafts to raise the mounting plate, or the three lower arms and three upper arms fold to lower the mounting plate, thereby adjusting the pitch angle and orientation of the mounting plate, thereby adjusting the angle at which multiple transmitting antennas one and multiple transmitting antennas two transmit interfering electromagnetic waves, and improving the interference effect.

[0014] Preferably, the UAV damage module includes a microwave pulse antenna and an infrared sensor. The microwave pulse antenna is mounted on a transmitting antenna, and the infrared sensor is mounted on a mounting plate. Multiple transmitting antennas face the rear of the UAV and emit microwaves to the UAV through the microwave pulse antenna. The microwaves heat and damage the electronic components of the UAV, thus damaging the UAV. The infrared sensor detects the temperature change of the UAV and evaluates the damage effect.

[0015] Preferably, the UAV damage module includes a cluster antenna, which is mounted on the transmitting antenna. The frequency of the electromagnetic waves emitted by the cluster antenna is the same as the natural frequency of the UAV's motor coil. The resonant frequency of the motor is determined by parameters such as its inductance and capacitance, and the specific calculation formula is as follows:

[0016] Resonance frequency = Electromagnetic waves at resonant frequencies cause the drone's motor coils to resonate. When the motor coils resonate, they generate heat, resulting in a decrease in power, which can cause the drone to crash and be damaged.

[0017] Compared with the prior art, the beneficial effects of the present invention are: it can simultaneously interfere with the UAV and the ground control terminal, improve the interference effect, and has a directional function, and concentrates the transmission of interference signals in the direction of the UAV and the direction of the ground control terminal, thereby reducing energy consumption, improving the interference effect, reducing false interference to normal equipment, and improving accuracy.

[0032] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0033] Example 1

[0034] like Figures 1 to 9 and Figure 11As shown, an omnidirectional multi-band UAV jamming antenna includes a main unit 1 and a mounting plate 2, with the mounting plate 2 mounted on the main unit 1. It also includes multiple pillars 3, multiple receiving antennas 4, multiple servo motors 5, multiple transmitting antennas 6, multiple servo motors 7, and multiple transmitting antennas 8. The pillars 3 are vertically mounted on the mounting plate 2 in a matrix arrangement. Multiple receiving antennas 4 are evenly mounted circumferentially on the outer walls of each pillar 3. Multiple servo motors 5 are mounted on the tops of the pillars 3. Multiple transmitting antennas 6 are mounted on the output shafts of the servo motors 5, and are concentrically arranged with the pillars 3. Multiple servo motors 7 are mounted on the tops of the transmitting antennas 6, and multiple transmitting antennas 8 are mounted on the output shafts of the servo motors 7. The main unit 1 includes a signal amplifier, a clock module, an analysis module, a storage module, a ground-based positioning module, and a UAV damage module. The signal amplifier amplifies the signals received by the multiple receiving antennas 4. The system includes a clock module for modifying the timestamp of the amplified signal, which is then transmitted through multiple transmitting antennas 6 and 8. An analysis module analyzes the received signal information and categorizes the signals. A storage module stores the categorized signals. A ground-end positioning module locates the ground-end position. A drone damage module damages the drone. The system also includes multiple fixed electrodes 9 and multiple moving electrodes 10. Multiple fixed electrodes 9 are evenly installed circumferentially on the upper ends of multiple columns 3, and are aligned with multiple receiving antennas 4. Multiple moving electrodes 10 are installed at the lower ends of transmitting antennas 6, located in the transmission direction of transmitting antennas 6, and aligned with the fixed electrodes 9. Furthermore, the system includes multiple brackets 11 and multiple moving electrodes 12. The upper ends of multiple brackets 11 are connected to multiple transmitting antennas 8, and moving electrodes 12 are installed at the lower ends of multiple brackets 11, aligned with the fixed electrodes 9.

[0035] Three pillars 3 are set up in an equilateral triangle arrangement. Thirty-six receiving antennas 4 are mounted on each pillar 3. Each of the three pillars 3 receives a signal from a specific direction. During operation, multiple receiving antennas 4 receive signals emitted by the UAV and signals emitted from the UAV's ground station. Based on the strength of the received signals from the UAV, multiple receiving antennas 4 generate electrical signals of varying strengths (either signal 1 or signal 2). The controller in the main unit 1 selects the receiving antenna 4 that generates the strongest electrical signal 1 and the receiving antenna 4 that generates the strongest electrical signal 2. At this time, the three receiving antennas 4 generating the strongest electrical signal 1 all point towards... The three receiving antennas 4 that generate the strongest electrical signal 2 are all oriented towards the ground end of the drone. The analysis module of the main unit 1 highlights the multiple fixed electrodes 9 that are aligned with the multiple receiving antennas 4 that generate the strongest electrical signal 1. When the multiple servo motors 5 drive the multiple transmitting antennas 6 to rotate, the multiple transmitting antennas 6 respectively drive the multiple moving electrodes 10 to rotate synchronously. When the multiple moving electrodes 10 are aligned with the highlighted fixed electrodes 9, the multiple servo motors 5 stop rotating. At this time, the transmission direction of the multiple transmitting antennas 6 is all towards the drone, improving the sensitivity of the multiple transmitting antennas 6. The multiple moving electrodes 12 are located outside the multiple fixed electrodes 9 to avoid collision with the moving electrodes 10. The analysis module of the main unit 1 highlights the multiple fixed electrodes 9 that are aligned with the multiple receiving antennas 4 that generate the strongest electrical signal 2. When the multiple servo motors 2 7 drive the multiple transmitting antennas 2 8 to rotate, the multiple transmitting antennas 2 8 respectively drive the multiple brackets 11 and the moving electrodes 2 12 to rotate synchronously. When the multiple moving electrodes 2 12 are aligned with the highlighted fixed electrodes 9, the multiple servo motors 2 7 stop rotating. At this time, the transmission directions of the multiple transmitting antennas 2 8 are all facing the ground end of the UAV, so that the transmission directions of the three transmitting antennas 1 6 are aligned with the three receiving antennas 4 that generate the strongest electrical signal 1. The three transmitting antennas 1 6 emit interfering electromagnetic wave signals to interfere with the UAV, and the UAV is in the position of the three transmitting antennas 1 6. In the area where the interfering electromagnetic wave signals of transmitting antenna 16 converge, the interference effect on the UAV is enhanced. At the same time, the transmission directions of the three transmitting antennas 28 are aligned with the three receiving antennas 4 that generate the strongest electrical signal 2. The three transmitting antennas 28 emit interfering electromagnetic wave signals to interfere with the UAV's ground end. Since the UAV's ground end is located in the area where the interfering electromagnetic wave signals of the three transmitting antennas 28 converge, the interference effect on the UAV's ground end is enhanced. Compared with the existing technology, it interferes with both the UAV and the ground control end at the same time, improves the interference effect, and has a directional function. It concentrates the transmission of interference signals in the direction of the UAV and the direction of the ground control end, reduces energy consumption, improves the interference effect, and reduces false interference to normal equipment.

[0036] After multiple receiving antennas 4 receive signals from the UAV and the ground terminal, the signal amplifier amplifies the signals, and the clock module modifies the timestamp of the amplified signals to generate repeating strong signals of the same type as those emitted by the UAV and the ground terminal. These strong signals will block the communication channels between the UAV and the ground terminal, increase the amount of signals that the processors of the UAV and the ground terminal have to process, causing the processors to overload and lag, or insert interference signals into the command list of the UAV, causing the UAV to execute incorrect commands, thereby interfering with the UAV and the ground terminal. The interference signal changes at any time according to the frequency hopping of the signals received by the multiple receiving antennas 4, realizing full-band and all-round interference. The ground terminal positioning module locates the position of the ground terminal, thereby counteracting the ground terminal. The UAV damage module physically damages the UAV to ensure stable interference effect.

[0037] Example 2

[0038] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, based on Embodiment 1, a ground-end positioning module is installed in the main unit chassis 1. The ground-end positioning module is used to locate the geographical location of the ground end. The ground-end positioning module includes a self-localization unit, a marker model unit, a fitting unit, a reading unit, and a navigation map unit. The self-localization unit is used to locate the geographical location of the main unit chassis 1. The navigation map module is used to understand the surrounding geographical environment of the main unit chassis 1 and, in conjunction with the self-localization unit, locates the main unit chassis 1 on the map. The marker model unit has a built-in positioning model. The positioning model numbers multiple pillars 3 and multiple receiving antennas 4. The positioning model divides the area around the main unit chassis 1 into several positioning grids, which are based on the pillars 3 and 4. The column 3 and receiving antenna 4 are numbered and marked. The fitting unit is used to fit several positioning grids of the marked model unit with the map, so that each positioning grid corresponds to a geographical location on the map. The reading unit is used to read the numbers of multiple receiving antennas 4 facing the UAV and multiple receiving antennas 4 on multiple columns 3 facing the UAV ground end, and determine the number of the corresponding positioning grid. The determined positioning grid is the probabilistic position of the ground end. It also includes a communication module 13, which is installed on the main unit 1 and is connected to the ground end positioning module. The communication module 13 is used to send the UAV ground end position data obtained by the ground end positioning module.

[0039] The specific construction method of the positioning model is as follows: Three pillars 3 are set up, and thirty-six receiving antennas 4 are set on the pillars 3. The three pillars 3 are labeled A, B, and C. The thirty-six receiving antennas 4 on A are labeled a1, a2, a3...a36, and a1, a2, a3...a36 divide the space around A into thirty-six sectors, labeled A1, A2, A3...A36, respectively. The thirty-six receiving antennas 4 on B are labeled b1, b2, b3...b36, and b1, b2, b3...b36 divide the space around B into thirty-six sectors, labeled B1, B2, B3...B36, respectively. The thirty-six receiving antennas 4 on C are labeled c1, c2, c3...c36, c...c ... 1. Divide the space around C into thirty-six sectors, c1, c2, c3...c36, and label them C1, C2, C3...C36 respectively. Let Ax be any one of A1, A2, A3...A36; By be any one of B1, B2, B3...B36; and Cz be any one of C1, C2, C3...C36. The area where Ax and By intersect, i.e., the secondary positioning grid, is labeled AxBy; the area where Ax and Cz intersect, i.e., the secondary positioning grid, is labeled AxCz; the area where By and Cz intersect, i.e., the secondary positioning grid, is labeled ByCz; and the area where Ax, By, and Cz intersect, i.e., the primary positioning grid, is labeled AxByCz. The primary positioning grid represents the high-probability position at the ground end, and the secondary positioning grid represents the probability position at the ground end.

[0040] The fitting unit positions the main unit 1 on the map provided by the navigation map unit based on the positioning information from the self-localization unit, and fits the positioning model onto the navigation map with the main unit 1 as the center. The reading unit reads the numbers Ax, By, and Cz of the receiving antennas 4 facing the ground on the three pillars 3 (A, B, and C) to determine the number of the main positioning cell AxByCz, and the numbers of the secondary positioning cells AxBy, AxCz, and ByCz. The specific location areas of the corresponding main positioning cell AxByCz and the secondary positioning cells AxBy, AxCz, and ByCz are obtained from the navigation map to complete the probabilistic positioning of the UAV on the ground. The method is simple and improves the positioning speed by using pre-marking.

[0041] The communication module 13 will send the obtained location information of the UAV ground terminal to the countermeasure unit. The countermeasure unit will first countermeasure the high-probability location. If the UAV ground terminal signal does not disappear, it will countermeasure the probability location and expand the countermeasure range with the high-probability location as the center until the UAV ground terminal signal disappears, thus completely eliminating the harm of illegal UAVs.

[0042] Example 3

[0043] like Figure 1 , Figure 2 , Figure 11 , Figure 12and Figure 13 As shown, based on Embodiment 1, it also includes a radar mount 14 and multiple radar modules 15. The radar mount 14 is installed in the middle of the mounting plate 2, and multiple radar modules 15 are installed on the radar mount 14. It also includes a central column 16, push rods 17, a lower support arm 18, an upper support arm 19, a ball joint rod 20, and a ball seat 21. Three push rods 17, three lower support arms 18, three upper support arms 19, three ball joint rods 20, and three ball seats 21 are provided. The central column 16 is installed in the middle of the main unit housing 1. The three push rods 17 are evenly arranged around the circumference of the central column 16. The inner ends of the three push rods 17 are rotatably connected to the central column 16, and the outer ends of the three push rods 17 are rotatably connected to multiple hinge shafts respectively. The lower ends of the three lower support arms 18 are rotatably mounted on the main unit housing 1. The upper ends of the three lower support arms 18 are rotatably connected to multiple hinge shafts. The lower ends of the three upper support arms 19 are rotatably connected to three hinge shafts. Ball head rods 20 are mounted on the upper ends of the three upper support arms 19. The three ball head rods 20 are movably connected to three ball seats 21. The three ball seats 21 are evenly mounted on the lower end surface of the mounting plate 2. The UAV damage module includes a microwave pulse antenna and an infrared sensor. The microwave pulse antenna is mounted on the transmitting antenna 6, and the infrared sensor is mounted on the mounting plate 2. The UAV damage module includes a cluster antenna, which is mounted on the transmitting antenna 6.

[0044] The radar module 15 can be a lidar, phased array radar, etc. By installing the radar mount 14 and the radar module 15, the UAV can be detected at a long distance, the UAV can be detected earlier, and multiple transmitting antennas 1-6 can be guided to interfere, improving accuracy. The three push rods 17 extend and retract respectively, so that the three push rods 17 push the three lower support arms 18 and the three upper support arms 19 vertically through the three hinge shafts to raise the mounting plate 2, or the three lower support arms 18 and the three upper support arms 19 fold to lower the mounting plate 2, thereby adjusting the pitch angle and orientation of the mounting plate 2, thereby adjusting the angle at which the multiple transmitting antennas 1-6 and multiple transmitting antennas 2-8 emit interference electromagnetic waves, improving the interference effect. After the multiple transmitting antennas 1-6 are oriented towards the UAV, they emit microwaves to the UAV through microwave pulse antennas. The microwaves heat and damage the electronic components of the UAV, damaging the UAV. Infrared sensors detect the temperature change of the UAV and assess the damage effect.

[0045] The frequency of the electromagnetic waves emitted by the cluster antenna is the same as the natural frequency of the UAV's motor coils. The resonant frequency of the motor is determined by parameters such as its inductance L and capacitance C, and the specific calculation formula is as follows:

[0046] Resonance frequency = Electromagnetic waves at resonant frequencies cause the drone's motor coils to resonate. When the motor coils resonate, they generate heat, resulting in a decrease in power, which can cause the drone to crash and be damaged.

[0047] like Figures 1 to 13As shown, this invention discloses an omnidirectional multi-band UAV jamming antenna. During operation, multiple receiving antennas 4 first receive signals emitted by the UAV and signals emitted from the UAV's ground terminal. The multiple receiving antennas 4 generate electrical signals of varying strengths based on the strength of the received signals from the UAV's ground terminal. Simultaneously, the multiple receiving antennas 4 generate electrical signals of varying strengths based on the strength of the received signals emitted from the UAV's ground terminal. The controller in the main unit 1 selects the receiving antennas 4 that generate the strongest electrical signal 1 and the receiving antennas 4 that generate the strongest electrical signal 2, and highlights the corresponding fixed electrodes 9. At this time, the three receiving antennas 4 generating the strongest electrical signal 1 are all facing the direction of the UAV, and the three receiving antennas 4 generating the strongest electrical signal 2 are all facing the direction of the UAV's ground terminal. Then, three servo motors 5 drive three transmitting antennas 6 to rotate. When the multiple servo motors 5 drive the multiple transmitting antennas 6 to rotate, the multiple transmitting antennas 6 drive multiple moving electrodes 10 to rotate synchronously. When the multiple moving electrodes 10 are aligned with the highlighted fixed electrodes 9, the multiple servo motors 5 stop rotating. At this time, the transmission directions of the multiple transmitting antennas 6 are all facing the direction of the UAV. When servo motor 27 drives multiple transmitting antennas 28 to rotate, the multiple transmitting antennas 28 drive multiple brackets 11 and moving electrodes 22 to rotate synchronously. When the multiple moving electrodes 22 are aligned with the multiple fixed electrodes 9 that are highlighted, the multiple servo motors 27 stop rotating. At this time, the transmission directions of the multiple transmitting antennas 28 are all facing the direction of the UAV ground end. Then, three transmitting antennas 16 emit interference electromagnetic wave signals to interfere with the UAV. The UAV is located in the intersection area of ​​the interference electromagnetic wave signals of the three transmitting antennas 16, which enhances the interference effect on the UAV. At the same time, the three servo motors 27 drive the three transmitting antennas 28 to rotate, so that the transmission directions of the three transmitting antennas 28 are aligned with the three receiving antennas 4 that generate the strongest electrical signal 2. The three transmitting antennas 28 emit interference electromagnetic wave signals to interfere with the UAV ground end. The UAV ground end is located in the intersection area of ​​the interference electromagnetic wave signals of the three transmitting antennas 28, which enhances the interference effect on the UAV ground end. Finally, the ground end positioning module marks the position of the ground end on the map, so that the countermeasure unit can counter the UAV ground end. The UAV damage module can then physically damage the UAV.

[0048] The main functions achieved by this invention are:

[0049] 1. It can simultaneously perform directional jamming on both UAVs and ground control terminals, improving jamming effectiveness, reducing energy consumption, and increasing accuracy;

[0050] 2. It can locate the ground-based drone, supporting countermeasures by ground-based units;

[0051] 3. The pitch angle and orientation of the mounting plate 2 can be adjusted, thereby adjusting the angle at which multiple transmitting antennas 6 and 8 emit interfering electromagnetic waves, thus improving the interference effect;

[0052] 4. It can damage drones and counteract interference with anti-jamming drones such as fiber optic drones.

[0053] The omnidirectional multi-band UAV jamming antenna of this invention uses common mechanical methods for installation, connection, or setup, and any method that achieves the desired beneficial effect can be implemented. The main unit 1, mounting plate 2, column 3, receiving antenna 4, servo motor 1 5, transmitting antenna 1 6, servo motor 2 7, transmitting antenna 2 8, fixed electrode 9, moving electrode 1 10, moving electrode 2 12, communication module 13, radar mount 14, radar module 15, push rod 17, ball joint rod 20, ball mount 21, signal amplifier, clock module, analysis module, storage module, microwave pulse antenna, infrared sensor, and cluster antenna are all commercially available.
