Abstract

The invention discloses a GNSS antenna for interfering an unmanned aerial vehicle. The antenna comprises a feed panel, a radiant panel, a coupling plate, a feed column, a metal plate and a support column, the feed panel is arranged on the metal plate, a feed network and a directional coupler are arranged on the feed panel, the directional coupler is connected with the feed network, a radiation unit is arranged on the radiation panel, two ends of the feed column are respectively connected with the directional coupler and the radiation unit, and the directional coupler is connected with the radiation unit. The radiation plate is located above the feed plate, a coupling unit is arranged on the coupling plate, one end of the supporting column is arranged on the feed plate, the other end of the supporting column penetrates through the radiation unit and is connected to the coupling unit, and the coupling plate is located above the radiation plate; the metal plate is provided with a signal interface, and one end of the signal interface is connected with the feed network. The GNSS antenna for interfering the unmanned aerial vehicle disclosed by the invention is narrow in wave beam, high in antenna gain and farther in effective distance of interference signals, and circular polarization of a broadband is realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle signal interference, in particular to a GNSS antenna for an unmanned aerial vehicle jammer. Background technique [0002] At present, the existing unmanned aerial vehicle jammers on the market all interfere with three frequency bands: WIFI2.4GHz, WIFI5.8GHz, and GPSL1, 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 the take-off, navigation, hovering and returning of the UAV...
