Abstract

A waveguide radiator includes a slotted waveguide with a plurality of transverse or longitudinal slots provided in the waveguide and an additional inner conductor provided in the waveguide. The inner conductor is formed, depending on the alignment of the slots in such a manner that the result is a feed according to the traveling wave principle, wherein all slots of the waveguide can be excited with identical phase.
