A microwave transmitting antenna with omnidirectional pattern in the horizontal plane is described which consists of six horn radiators and six plane reflectors arranged in a hexagonal configuration. Each reflector illuminates an azimuthal sector of approximately 60°. If therefore, a sector-shaped horizontal pattern is required, less than six reflectors need to be provided.
