Abstract :
In this paper, a new concept to obtain an azimuthal shaping of an omnidirectional antenna pattern for MM-waves is presented. A dual reflector antenna with parabolic subreflector, conical main reflector and a suitable feed exhibits an omnidirectional pattern: here the conical main reflector is modified in its azimuthal shape in order to produce a nonuniform power distribution in azimuth. Examples and design criteria are presented.
