Abstract
An expression for the electric field of a dipole near a perfectly conducting wedge has been derived to appraise the Uniform Theory of Diffraction (UTD) in regions where it is expected to deviate from the exact solution, e.g. the near field. This expression, obtained using the theory of Green’s functions, has been evaluated using numerical integration. First the solution is verified for the case of a dipole near a ground plane, which can also be calculated using image theory. Next the numerical solution for the near field is compared to results obtained with the UTD-method for different parameter configurations. The most striking difference occurs when the angle of the wedge is sharp and both the source and observer are located within a few wavelengths from the edge.
