| description | The invention relates to an antenna device and an unmanned aerial vehicle with the antenna device. The antenna device comprises a dielectric substrate; and the dipole unit is arranged on the dielectric substrate and comprises a pair of vibration arms which are symmetrical along the first symmetric axis, each vibration arm is provided with a first radiation edge and a second radiation edge, and the first radiation edge is closer to the feeding point than the second radiation edge. Since the first radiation edge is closer to the feeding point than the second radiation edge, the dipole unit can realize resonance in a first working frequency band with higher frequency through the first radiation edge, and can also realize resonance in a second working frequency band with lower frequency through the second radiation edge. Through the implementation mode, the antenna device can work in the first working frequency band with higher frequency and can also work in the second working frequency band with lower frequency, |
