Abstract :
A full-wave numerical study of 2-D models of dual-reflector omnidirectional ADE (axially-displaced ellipse subreflector and parabolic main reflector) and PACO (parabolic subreflector and conical/corner reflector) antennas is performed in the E-polarization case. The analysis is based on the recently developed method of discrete singularities (MDS) which uses coupled singular electric-field integral equations (SIE) applied to accurate modelling of the considered axially-symmetric dual-reflector (actually, three-reflector in the considered 2-D case) antenna systems.
