Abstract

In this work an axially-displaced-ellipse (ADE) dual-reflector antenna is suggested for the achievement of an omnidirectional coverage. Its geometry is briefly presented and some relevant features are compared against previously suggested reflector antennas, designed for the same purpose. The present antenna configuration is capable of yielding the desired aperture illumination with relatively smaller reflector dimensions, providing a compact arrangement suited for use at the base station of point-to-multi-point radio links. Numerical simulations are presented to illustrate the usefulness of the proposed reflector antenna.
