Abstract

High frequency asymptotic techniques (HFAT) were used to analyze large reflector antenna systems. An equivalence surface was used to separate the low-frequency domain from the high frequency domain. A dielectric sphere was used to validate the hybrid formulation. The method's capability was tested by feeding the reflector with a dielectric loaded waveguide. The absolute gain pattern of the given configuration was computed by using the hybrid method and compared with the pure finite element method (FEM). The prediction of the iteration method exhibited excellent agreement after three to four iterations.
