Abstract :
A waveguide slot element, excited by a thin strip, printed and kept behind the slot is presented. The slot is vertical and non-wrap around, whereas the strip is inclined with respect to the slot or takes an L-shape. The strip and the slot are printed simultaneously on a dielectric substrate and replaces the narrow wall of the guide. The use of printed circuit technique leads to good accuracy and square ended slots. A wide range of admittance can be realised by choosing the strip parameters
