Time-effective and accurate synthesis of large-aperture slotted waveguide antennas

A time-effective and accurate approach to the synthesis of slotted-waveguide antennas (SWA) is proposed. The approach is based on a combined usage of a full-wave simulation and physical properties of SWA. The approach has been successfully applied to the development of a large-aperture Ka-band antenna with a 1 meter aperture. This development is illustrated by the corresponding both simulation and experimental results.
