The wedge-diffraction theory in combination with the creeping wave theory is used to compute the radiation pattern of an axial slot on a circular conducting cylinder. The slot is excited by a parallel-plate waveguide operating in the TEM-mode. The total field in the “lit” region is obtained by the superposition of the wedge-diffracted and creeping wave fields. The total field in the “shadow” region is obtained solely from the creeping wave con-tribution.
