Problems solved by technology

[0004] However, since the entire radiation unit and antenna ground unit of the prior art drone antenna are all located on the same side of the substrate, the efficiency of the antenna is low; moreover, when the thickness of different positions of the substrate is inconsistent, it will cause resonance of the antenna Frequency offset, which in turn reduces antenna efficiency

Abstract

The invention provides an antenna and an unmanned aerial vehicle. The antenna can be installed outside a vehicle body of the unmanned aerial vehicle, and the antenna comprises a substrate, a coaxial line, a first radiating unit and a first antenna unit; the substrate is provided with a first face and a second face which are back to each other; the first radiating unit comprises a first radiating part arranged on the first face and a second radiating part which is arranged on the second face and electrically connected with the first radiating part, and the current path lengths of the first radiating part and the second radiating part are equal; the first antenna ground unit comprises a first antenna ground part arranged on the first face and a second antenna ground part which is arranged onthe second face and electrically connected with the first antenna ground part, and the current path lengths of the first antenna ground part and the second antenna ground part are equal; the first radiating unit and the first antenna ground unit feed through the coaxial line, therefore, it is guaranteed that electromagnetic waves on the two sides of the antenna substrate can perform harmonic vibration at the same resonant frequency, and the radiant efficiency of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna and an unmanned aerial vehicle.
