Title:
BUILT-IN ANTENNA OF UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/157830
Kind Code:
A1
Abstract:
Disclosed are a built-in antenna of an unmanned aerial vehicle, and an unmanned aerial vehicle. The built-in antenna of the unmanned aerial vehicle comprises a substrate and a microstrip antenna provided on the substrate. The substrate is provided with a first face and a second face, which are arranged opposite each other. The microstrip antenna comprises: a microstrip feeder line, an antenna oscillator arm, a ground return line and a first grounding end provided on the first face of the substrate; a second grounding end provided on the second face of the substrate; and a feed coaxial line, wherein a feed end of the feed coaxial line is connected to a first end of the microstrip feeder line, and a grounding end of the feed coaxial line is connected to the first grounding end; a first end of the of the ground return line is connected to a first end of the antenna oscillator arm, and a second end of the ground return line is connected to the first grounding end; the first grounding end is connected to the second grounding end; and the second end of the microstrip feeder line is connected to the antenna oscillator arm. The built-in antenna of an unmanned aerial vehicle provided by the present invention can meet the space and size requirements for building same in the unmanned aerial vehicle, and the influence of the environmental interference is small due to the presence of the second grounding end.
