Directional countering unmanned aerial vehicle antenna

Abstract

The invention discloses a directional countering unmanned aerial vehicle antenna, and belongs to the technical field of antennae, the directional countering unmanned aerial vehicle antenna comprises a takeoff and landing support, two fixed cross rods are installed on the takeoff and landing support, an adjusting mechanism is arranged between the two fixed cross rods, three receiving and transmitting antennas are connected to the adjusting mechanism at intervals, and the adjusting mechanism comprises an elliptical track. The fixing transverse rod is sleeved with the oval track, electromagnetic attraction pieces are evenly arranged on the surface of the oval track, a limiting guide rail is fixedly arranged on the periphery of the outer side of the oval track, a sliding base is slidably connected to the limiting guide rail, and movable chain plates are arranged on the two sides of the bottom end of the sliding base. Fixed side rods are connected to the two sides of the movable chain plate, and a magnetic rod is embedded into one side of the interior of each fixed side rod, so that the electromagnetic adjustment function of the receiving and transmitting antenna at the elliptical orbit position can be quickly realized, and the anti-interference performance of the unmanned aerial vehicle is improved.

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
