Antenna, Method of Manufacturing an Antenna and Apparatus for Manufacturing an Antenna
, 2006 An antenna comprises a plurality of re-radiating elements arranged in at least one plane being parallel to a fixed surface. The arrangement is adapted such that electromagnetic radiation emitted from the re-radiating elements in response to electromagnetic radiation arriving from a predetermined direction interferes constructively at a feed location ...

Structure-Independent Conformal Quasi-Isotropic Antennas for Small Unmanned Aircraft System Applications [PDF]
, 2017 Communication systems for aircraft are often implemented through antennas that protrude from the airframe and contain radiation nulls - which have detrimental effects on the aerodynamics of the craft and its ability to maintain a strong data link with a ...
