Abstract :
Dual-reflector antennas have been investigated for omnidirectional coverage, where the reflector surfaces are bodies of revolution obtained by spinning confocal conic sections or shaped generating curves about a common symmetry axis. The aim of this work is to complement the previous investigations by deriving the GO aperture held of omnidirectional axis-displaced dual-reflector antennas with an arbitrary main-beam direction in the elevation plane.
