Abstract (en)
[origin: CA2857658A1] Described is a waveguide radiator which comprises a slotted waveguide (10; 30) with a plurality of transverse or longitudinal slots (23; 32) provided in the waveguide (10; 30) and which comprises an additional inner conductor (14; 34) provided in the waveguide (10; 30), wherein the inner conductor (14; 34) is formed, depending on the alignment of the slots (12, 32) in such a manner that the result is a feed according to the traveling wave principle, wherein all slots (12; 32) of the waveguide (10; 30) can be excited with identical phase.
