Resumo:
The characteristics of a reflector antenna radiating omnidirectionally in azimuth with a cosecant-squared power pattem in vertical planes, as intended for point-tomultipoint services in the millimetric wave range and comprising a single circularly symmetrical shaped reflector surface fed by an axial horn, were presented in [I], as an altemative to configurations reported elsewhere, involving nodal stations with up to four antennas for quadrant sectors coverage [2] or dual reflector arrangements for omnidirectional coverage [3]. Reported results, considering a rigorous feed model for the constructed prototype, then highlighted the main features of the proposed design. The present work extends the previous investigation by considering the effect of employing larger feed apertures yielding more collimated primary fields, with a view towards synthesizing more compact reflector surfaces.
