Abstract
This work presents a simple formulation to synthesize amplitude and phase distributions at cylindrical apertures of omnidirectional dual-reflector antennas. Adopting a tapered amplitude, the phase is obtained to provide an omnidirectional cosecant-squared radiation pattern with low sidelobe levels. Initially, the synthesis formulation is validated by the aperture method. Then, two distinct omnidirectional dual-reflector configurations are shaped and their radiation patterns are simulated by full-wave method-of-moments analyses and by ANSYS HFSS, to illustrate the usefulness of the synthesis technique.
