Summary:
Rotating-mode feed transitions from the coaxial line to the three-layered radial waveguide are proposed. The rotating mode with amplitude deviation of 4.5 dB and phase deviation of 39deg is realized by the transition with a circular patch model with notched for perturbation. Confirmation by measurements and design of slots on the radial waveguide are future tasks.
