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.

Abstract: The present invention provides an unmanned aerial vehicle built-in dual-band antenna and an unmanned aerial vehicle. The unmanned aerial vehicle built-in dual-band antenna includes a first frequency band microstrip antenna and a second frequency band microstrip antenna. The first frequency band microstrip antenna includes a first substrate, a first microstrip feeder and a grounding terminal that are disposed on a first surface of the first substrate, a grounding terminal disposed on a second surface of the first substrate and a feeding coaxial line. A feed terminal of the feeding coaxial line is connected to a first terminal of the first microstrip feeder, and a grounding terminal of the feeding coaxial line is connected to the grounding terminal of the first surface. The grounding terminal of the first surface is connected to the grounding terminal of the second surface. The second frequency band microstrip antenna includes a second substrate and a second microstrip feeder disposed on the second substrate. The first frequency band microstrip antenna is connected to the second frequency band microstrip antenna.
