Various drone jamming antennas are disclosed in the prior art, such as the Chinese invention patent publication number CN118431733B, which proposes an antenna system for a drone jamming gun and a drone jamming gun. The drone jamming gun's antenna system is layered with a top layer, a middle layer, and a bottom layer. The structure includes an omnidirectional detection antenna, a detection antenna assembly, a jamming antenna assembly, and a navigation decoy antenna.

When working, multiple receiving antennas 4 receive signals sent by the UAV and signals sent by the UAV ground end. The multiple receiving antennas 4 generate electrical signal 1 of different intensities according to the strength of the signals sent by the UAV received. At the same time, the multiple receiving antennas 4 generate electrical signal 2 of different intensities according to the strength of the signals sent by the UAV ground end received. The controller in the main box 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.

The countermeasure unit first counters the high-probability position. If the drone ground end signal has not disappeared, it counters the probable position and expands the countermeasure range with the high-probability position as the center until the drone ground end signal disappears, completely eliminating the harm of illegal drones.

[0025] Example 3 like Figure 1 、 Figure 2 、 Figure 11 、 Figure 12 and Figure 13As shown, on the basis of embodiment 1, it also includes a radar base 14 and multiple radar modules 15, the radar base 14 is installed in the middle of the mounting plate 2, and multiple radar modules 15 are installed on the radar base 14; it also includes a center column 16, a push rod 17, a lower support arm 18, an upper support arm 19, a ball head rod 20 and a ball seat 21, and three push rods 17, lower support arm 18, upper support arm 19, ball head rod 20 and ball seat 21 are provided. The center column 16 is installed in the middle of the main box 1, and the three push rods 17 are evenly arranged around the circumference of the center column 16. The inner ends of the three push rods 17 are rotatably connected to the center column 16, and the outer ends of the three push rods 17 are rotatably connected to multiple hinge shafts respectively. The lower end of each lower arm 18 is rotatably mounted on the main chassis 1, the upper ends of the three lower arms 18 are rotatably connected to multiple hinge shafts respectively, the lower ends of the three upper arms 19 are rotatably connected to three hinge shafts respectively, the upper ends of the three upper arms 19 are all installed with ball head rods 20, the three ball head rods 20 are movably connected to three ball sockets 21 respectively, and the three ball sockets 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, and the cluster antenna is mounted on the transmitting antenna 6.

[0026] The radar module 15 can be a laser radar, a phased array radar, etc. By installing the radar base 14 and the radar module 15, the drone can be detected from a distance, the drone can be discovered earlier, and the multiple transmitting antennas 6 can be guided to interfere, thereby improving accuracy; the three push rods 17 are respectively extended and retracted, so that the three push rods 17 respectively push the three lower arms 18 and the three upper arms 19 through the three hinged shafts to vertically push the mounting plate 2 up, or the three lower arms 18 and the three upper arms 19 are folded to lower the mounting plate 2, thereby adjusting the pitch angle and direction of the mounting plate 2, thereby adjusting the angle of the multiple transmitting antennas 16 and the multiple transmitting antennas 28 to transmit interfering electromagnetic waves, thereby improving the interference effect. After the multiple transmitting antennas 6 are directed towards the drone, microwaves are emitted to the drone through the microwave pulse antenna. The microwaves heat and damage the electronic components of the drone, thereby damaging the drone. The infrared sensor detects the temperature change of the drone and evaluates the damage effect; The frequency of the electromagnetic waves emitted by the cluster antenna is the same as the natural frequency of the drone's motor coil. The resonant frequency is determined by the inductance (L) and capacitance (C) of the motor coil, and is calculated as: resonant frequency = 1 / (2π√LC). The electromagnetic waves at the resonant frequency cause the drone's motor coil to resonate. When the motor coil resonates, it heats up and loses power, causing the drone to crash and be damaged.

[0027] like Figures 1 to 13As shown, the present invention is an omnidirectional multi-band UAV jamming antenna. When it is working, first, multiple receiving antennas 4 receive signals emitted by the UAV and signals emitted by the UAV ground end. The multiple receiving antennas 4 generate electrical signals of different strengths according to the strength of the signals received by the UAV. At the same time, the multiple receiving antennas 4 generate electrical signals of different strengths according to the strength of the signals received by the UAV ground end. The controller in the main box 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 and highlights the corresponding fixed electrodes 9. At this time, the three receiving antennas 4 that generate the strongest electrical signal 1 are all facing the direction of the UAV, and the three receiving antennas 4 that generate the strongest electrical signal 2 are all facing the direction of the UAV ground end. Then, three servo motors 15 respectively drive the three transmitting antennas 6 to rotate. When the multiple servo motors 15 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 respectively aligned with the multiple fixed electrodes 9 that are highlighted, 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 a servo motor 27 drives the multiple transmitting antennas 28 to rotate, the multiple transmitting antennas 28 respectively drive the multiple brackets 11 and the movable electrodes 212 to rotate synchronously. When the multiple movable electrodes 212 are respectively aligned with the multiple fixed electrodes 9 with prominent marks, the multiple servo motors 27 stop rotating. At this time, the transmission directions of the multiple transmitting antennas 28 are all towards the direction of the ground end of the drone. Then the three transmitting antennas 16 emit interfering electromagnetic wave signals to interfere with the drone, and the drone is in the intersection area of the interfering electromagnetic wave signals of the three transmitting antennas 16, thereby enhancing the interference effect on the drone. At the same time, the three servo motors 27 respectively drive the three transmitting antennas 28 to rotate, so that the transmission directions of the three transmitting antennas 28 are respectively aligned with the three receiving antennas 4 that generate the strongest electrical signals 2. The three transmitting antennas 28 emit interfering electromagnetic wave signals to interfere with the ground end of the drone, and the ground end of the drone is in the intersection area of the interfering electromagnetic wave signals of the three transmitting antennas 28, thereby enhancing the interference effect on the ground end of the drone. Finally, the ground end positioning module marks the position of the ground end on the map, so that the countermeasure unit can counter the ground end of the drone, and the drone damage module can physically damage the drone.

[0028] The main functions achieved by the present invention are: 1. It can simultaneously carry out directional interference on the UAV and the ground control terminal, improve the interference effect, reduce energy consumption, improve the interference effect, and have better accuracy; 2. Ability to locate the ground terminal of the drone and support countermeasure units to counter the ground terminal; 3. The pitch angle and orientation of the mounting plate 2 can be adjusted, thereby adjusting the angles at which the multiple transmitting antennas 1 6 and the multiple transmitting antennas 2 8 transmit interfering electromagnetic waves, thereby improving the interference effect; 4. It can destroy drones and interfere with and counter-interference drones such as fiber-optic drones that are resistant to interference.
