Conformal end-fire antennas for unmanned aerial vehicles

摘要

This paper introduces three types of conformai low-profile end-fire antennas that can be mounted on the unmanned aerial vehicles. They include a narrow H-plane waveguide horn, a log-periodic top-hat monopole antenna, and a planar helix antenna of circular polarization. Experimental models and measurement results are presented to verify the design concepts and assess their radiation performance. These conformal, wideband, and low-profile antennas are conductor-backed, and can obtain nearly end-fire radiations over an ultra-wide bandwidth, which are potentially very useful in airborne communication applications.
