Abstract (en)
[origin: US4513291A] Each radiating slot having a length L in the vicinity of the operating wavelength lambda of a direct-radiation slotted rectangular waveguide is placed on one side of the waveguide so as to be parallel to the lines of current flow and is provided with a transverse stepped section formed at the center of the slot at right angles to the current lines.
