GO shaping of omnidirectional dual-reflector antennas for maximum gain

This work presents the formulation for the reflector shaping of dual-reflector antennas designed to offer an omnidirectional coverage. The shaping is based on geometrical optics (GO) principles and assumes a uniform phase distribution for the aperture field. Two distinct dual-reflector arrangements (based on the ADC and ADE configurations) are investigated. The GO shaping results are validated by accurate analyses provided by the moment-method technique.
