It is especially well suited for low-profile geometries without axial symmetry that are currently being proposed as feeder systems for Ka-band lens antennas. By taking into account new features, such as large spherical surface consideration and dual electric field components, this modified algorithm results in improved designs for complete Ka-band, lens-based systems showing consistently an enhanced gain.planar feederslens antennasphase centerKa-bandtext::conference output::conference proceedings::conference paper
