Abstract: The present invention discloses a dual-band microstrip antenna and an unmanned aerial vehicle using same. The dual-band microstrip antenna includes: a substrate; a first-band microstrip antenna, disposed on a front surface of the substrate and configured to generate first-band resonance; a second-band microstrip antenna, disposed on a back surface of the substrate and configured to generate second-band resonance and high-order resonance of the second-band resonance, the high-order resonance of the second-band resonance being used to be superposed on the first-band resonance; and a coaxial feeder, configured to feed the first-band microstrip antenna and the second-band microstrip antenna. By means of embodiments of the present invention, the beamwidth of the dual-band microstrip antenna on a pitch surface at first-band resonance can be expanded, so that a stable signal can be kept when the antenna tilts.

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.

Abstract: The present application relates to the field of communications, and provides an antenna assembly which is disposed in a wireless communications electronic device. The wireless communications electronic device is provided with a substrate. The antenna assembly includes: a radiation element, disposed at a first surface of the radiation element; a feeder, electrically connected to the radiation element; and a reference ground, disposed at a second surface of the substrate. The antenna assembly in the embodiments of the present application uses the substrate of the wireless communications electronic device as a medium to bear the radiation element, reducing space and costs of the antenna assembly; and because the substrate is relatively thick, a bandwidth of the antenna assembly is also increased. The embodiments of the present application further provide a wireless communications electronic device having the antenna assembly.
