Abstract
A four-wire antenna system is analyzed in a tapered anechoic chamber using a frequency-domain finite-element technique. In the analysis, wedge absorbers are replaced by equivalent dielectric layers to reduce the number of unknowns. To handle the lossy medium (absorbers and loading resistances), full magnetic vector fields are used in the three-dimensional finite-element formulation. The system matrix equation is then solved using the frontal technique.<>
