Design of slotted waveguide antennas with low sidelobes for high power microwave applications

Abstract

Slotted waveguide antenna (SWA) arrays offer clear advantages in terms of their design, weight, volume, power handling, directivity, and efficiency. Slotted waveguide antennas (SWA) are often employed in radar applications where design specifications commonly require high gains and mechanical robustness. Since the peak power transmitted by radar antennas is usually very high, waveguide antennas present a practical alternative to planar arrays. While numerous design references and guidelines exist for planar arrays, they are far fewer for slotted waveguide antennas. In this report there is a complete workflow for the analysis and design of a slotted waveguide antenna with slots placed on the narrow wall of the waveguide. The platform use for design the model and simulate is HFSS Software
