Abstract :
Some radiation characteristics of a narrow nonresonant slot close to, or straddling, the centre line of a notched-wall dual-mode waveguide are presented, and compared with the behaviour of similar slots in the corresponding single-mode guide. The theoretical results have been evolved using Bethe´s small-hole diffraction theory. They are supported by some experimental evidence.
