Bandwidth Behavior of Omnidirectional Dual-Reflector Antennas Synthesized for Uniform Coverage

José R. Bergmann, Fernando J. S. Moreira

Abstract


This work presents a study on the electromagnetic behavior of omnidirectional dual-reflector antennas synthesized to provide uniform coverage. Special attention is paid to the antenna radiation pattern across a 10% bandwidth, in order to establish limits for the applicability of omnidirectional dual-reflector antennas in broadband communication services. Several case studies involving classical and shaped configurations are investigated. The results are validated by method-of-moments analysis.
