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, so that the supportable frequency band of the antenna device can be expanded on the premise that the size and the structural complexity of the antenna device are not increased.
本申请涉及一种天线装置和具有该天线装置的无人飞行器。该天线装置包括:介质基板;以及偶极子单元,设于介质基板上,并包括沿第一对称轴对称的一对振臂,其中每个振臂具有第一辐射边缘和第二辐射边缘,第一辐射边缘相较第二辐射边缘距离馈电点较近。由于第一辐射边缘相较第二辐射边缘距离馈电点较近,因此偶极子单元既能够通过第一辐射边缘实现在频率较高的第一工作频段内谐振,又能够通过第二辐射边缘实现在频率较低的第二工作频段内谐振。通过这种实现方式,天线装置既能够在频率较高的第一工作频段内工作,又能在频率较低的第二工作频段内工作,从而能够在不增加天线装置的尺寸和结构复杂程度的前提下,扩展天线装置的可支持的频带。
