Resumen
Proposing a novel hybrid uniform theory of diffraction-physical optics (UTD-PO) formulation,
we develop a method to calculate the E-plane radiation pattern of corrugated E-plane rectangular horn
antennas with rectangular corrugations. We derive the technique from the estimation of the total field that
reaches the emitting source (a magnetic current line), thereby assuming the impingement of a plane wave
above the horn (reciprocity is applied). To validate our method, we compare the performance of the UTD-PO
analysis with that of the electric field integral equation (EFIE) solved using the method of moments (MoM).
Our method shows improved computational efficiency over EFIE and other numerical techniques that fully
discretize the geometry.
