ABSTRACT:
A slot antenna element is provided in the form of a rectangular waveguide including at least one slot situated in the center of one broad side, a rectangular ridge arranged in the center of the interior surface of the other broad side, wherein the slot and the ridge each extend along the longitudinal direction of the waveguide, coupling devices, particularly a pin, arranged in the area of the slot, which excite the slot to emit electromagnetic energy, and compensation devices constructed on the surface of the ridge facing the slot, which compensation devices compensate the mismatch of the waveguide caused by the coupling devices with respect to the generator feeding the waveguide with electromagnetic energy. The compensation devices are constructed such that the ridge has a step-shaped indentation in the area of the slot.
