Abstract
The present invention provides an unmanned aerial vehicle built-in antenna. The unmanned aerial vehicle built-in antenna includes a substrate and a microstrip antenna disposed on the substrate. The substrate is provided with a first surface and a second surface disposed opposite to each other. The microstrip antenna includes a microstrip feeder, an antenna element arm, a grounding wire and a first grounding terminal that are disposed on the first surface of the substrate, a second grounding terminal disposed on the second surface of the substrate and a feeding coaxial line. A feed terminal of the feeding coaxial line is connected to a first terminal of the microstrip feeder, and a grounding terminal of the feeding coaxial line is connected to the first grounding terminal. A first end of the grounding wire is connected to a first terminal of the antenna element arm, and a second end of the grounding wire is connected to the first grounding terminal. The first grounding terminal is connected to the second grounding terminal.
