Comments on the phase center computation for ka-band planar lens-antenna feeders

This paper presents a modified methodology to compute the phase center of planar antennas. 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.
