A directional countermeasure drone antenna

Abstract

The invention discloses a UAV antenna for directional countermeasures, which belongs to the technical field of antennas, and comprises a landing bracket. Two fixed cross bars are installed on the landing bracket, and an adjustment mechanism is arranged between the two fixed cross bars. , the adjustment mechanism is connected with three transmitting and receiving antennas at intervals, the adjustment mechanism includes an elliptical track, and the elliptical track is sleeved outside the fixed crossbar, and the surface of the elliptical track is evenly provided with electromagnetic suction pieces, so The outer periphery of the elliptical track is fixed with a limit guide rail, and a sliding seat is slidably connected to the limit guide rail. Movable chain plates are arranged on both sides of the bottom end of the slide seat, and fixed chain plates are connected to both sides of the movable chain plate. The side rod, the inner side of the fixed side rod is embedded with a magnetic rod, which can quickly realize the electromagnetic adjustment function of the transceiver antenna at the position of the elliptical orbit, and improve the anti-jamming performance of the drone.

Description

technical field [0001] The present invention relates to the technical field of antennas, and more specifically, relates to a directional counter-measure drone antenna. Background technique [0002] As we all know, drones have been widely used in civil, industrial, military and other fields in recent years. Because drones are low in cost, easy to obtain, easy to operate, and easy to form black flights, lawbreakers use drones to illegally shoot key areas , Spy surveying and mapping, illegal delivery, sabotage explosions and other illegal activities have triggered a series of security incidents, so there is a directional counter drone. [0003] Among them, the authorized announcement number is (CN213184562U), a directional anti-drone antenna type, by pressing down the movable rod until the first antenna rod and the two second antenna rods are received inside the straight groove, and then rotate the movable rod to make the two The two limit blocks are snapped into the card slot...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a directional counter-response UAV antenna, which can realize the electromagnetic adjustment function of the transmitting and receiving antenna at the position of the elliptical orbit quickly, so that the UAV can be easily adjusted during flight. Make the transceiver antenna in the best position for signal reception, improve the anti-jamming performance of the UAV, and solve the problems of traditional antenna drive structure complex and high equipment failure rate
