DUAL-FREQUENCY-BAND MICRO-STRIP ANTENNA AND UNMANNED AERIAL VEHICLE USING SAME

摘要

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.
