Abstract In this work, an axially‐displaced‐ellipse (ADE) dual‐reflector antenna for the achievement of an omnidirectional coverage is proposed. Its geometry is briefly presented and some relevant features are compared against previously suggested reflector antennas, designed for the same purpose. The present ADE configuration is capable of yielding the desired aperture illumination with relatively smaller reflector dimensions, thus providing a compact arrangement suited for use at base stations of point‐to‐multi‐point radio links. Numerical simulations are presented to illustrate the usefulness and advantages of the proposed reflector antenna. © 2004 Wiley Periodicals, Inc.
