Numerical investigation of end- and centre-loaded slots

Abstract

The equivalence principle and the generalized network formulation are used to model the tangential electric field of arbitrary apertures backed by a rectangular waveguide or cavity, in terms of equivalent magnetic currents. The result is an integral equation for the unknown aperture current. This integral equation is then reduced to a matrix equation using the method of moments. Specifically, the numerical technique is applied to end- and center-loaded slot antenna configurations backed by a rectangular waveguide.<>
