GNSS antenna for unmanned aerial vehicle jammer

The invention discloses a GNSS antenna for an unmanned aerial vehicle jammer, the antenna comprises a feed panel, a radiation panel, a feed column and a metal plate, the feed panel is arranged on the metal plate, the feed panel is provided with a feed network and a directional coupler, the directional coupler is connected with the feed network, the radiation panel is provided with a radiation unit, and the radiation unit is connected with the feed column. One end of the feed column is connected with the directional coupler, the other end of the feed column is connected with the radiation unit, the radiation plate is located above the feed plate, the metal plate is provided with a signal interface, and the signal interface is connected with the feed network; the feed network comprises a main line and four branch lines, and the four branch lines are connected with the main line. Interference signals emitted by the antenna are narrow in wave beam, the antenna gain is high, the effective distance is farther, and
