The theory of diffraction by a perfectly conducting wedge of arbitrary angle applied to antenna patterns
Abstract
The complex integral equation derived from the theory of diffraction of light at a wedge limited by two perfectly conducting half planes is dealt with. (W. Pauli, 1938). This theory was applied to an electromagnetic wave and further developed and improved. The general complex integral equation of diffraction is stated, plotted numerically, and examined for the exterior as well as for the interior wedge. In case of a spherical incoming wave a number of far field diagrams of diffraction are plotted. The electrical field intensity is polarized vertically or horizontally to the edge. The fields are calculated for a vertical incidence of the spherical wave to the edge, for a distance from radiation point of 3 lambda and for several incidence angles to one half plane. The radiation fields of a mono respectively dipole are calculated using the diffraction field in the presence of a conducting plate with finite dimensions, of a rectangular conducting parallelepiped and of a 120 deg respectively 270 deg corner reflector. The theoretical results are partly compared with experimentally obtained patterns.
