The invention discloses a high-gain ultra-wideband unmanned aerial vehicle antenna, which comprises a dielectric substrate, and a first radiator and a second radiator printed on the front surface of the dielectric substrate, and a feed gap exists between the first radiator and the second radiator. According to the invention, two times of accurate impedance matching are realized through the first radiator, higher impedance bandwidth is realized, and the adaptability and flexibility of the antenna are improved. Besides, the first radiation patch of the first radiator adopts a trident-shaped design, so that a unique radiation mode and performance are provided for the antenna, and the gain and directivity of the antenna are improved. Through the specific layout of the first radiator and the second radiator, the uniform distribution of current in a working frequency band is realized, the antenna is endowed with an omnidirectional radiation characteristic, and the omnidirectional radiation characteristic is crucial to the communication of the unmanned aerial vehicle in various directions.
