Feeding system for antenna with omnidirectional characteristics

摘要

The system includes a feeding network which is arranged in several grooves (10,10') of a metallic profile rod (1). Only inner conductor (4) and the dielectric (5) is used for the feeder line set up. The groove boundary is used as earth. The profile rod is used as the carrier for radiators. Preferably, lateral grooves (11), slant grooves or holes are provided between the grooves for accommodating necessary power divider. The power divider is also located in the profile rod.
