Abstract

The invention discloses a GNSS (Global Navigation Satellite System) antenna array for an interference device. The antenna array comprises a first antenna, a second antenna and a metal plate, the first antenna and the second antenna are both arranged on the metal plate, the metal plate is provided with two signal interfaces, and the first antenna and the second antenna are respectively connected with one signal interface. The antenna array can interfere with most frequency bands in the GNSS of the unmanned aerial vehicle, so that the interference frequency band is wide, interference signals emitted by the antenna array are narrow in wave beam, the antenna gain is high, the effective distance is longer, and due to the fact that the interference signals are narrow in wave beam, the antenna interference direction angle is small and is within 25 degrees. And interference to other equipment can be avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle signal interference, in particular to a GNSS antenna array for jammers. Background technique [0002] At present, the existing UAV jammers on the market all interfere with WIFI2.4GHz, WIFI5.8GHz, GPSL1 three frequency bands, but the actual control and image transmission frequency bands of UAVs on the market are not only WIFI, there are 400MHz, 900MHz , 1.4GHz and other public frequency bands, and the positioning system is not only GPS L1, but also BD, GLONASS, GALIEO, QZSS and other positioning systems. At present, the GNSS positioning system is one of the key technologies to support the safe flight of UAVs. The UAV knows its precise position when it transmits video and images, so the UAV is equipped with a GNSS signal receiver, that is, a built-in GNSS module. In any stage of take-off, sailing, hovering, and returning of the UAV, the GNSS module is required for real-time precise...
