<p>PURPOSE:To compress the outer diameter of a feed system path, by constituting the microwave circuit part of a feed system passing a main axis to rotate a slot array with a coaxial pipe, and providing a rectangular waveguide-coaxial pipe solid conversion circuit on the upper end of the pipe. CONSTITUTION:A horizontal rectangular waveguide is feed-coupled with a very small vertical rectangular waveguide 13 on the upper end side of the main axis 15 via an E-plane corner 12. By providing the rectangular waveguide- coaxial pipe solid conversion circuit on the part of the vertical rectangular waveguide 13, the vertical rectangular waveguide 13 is feed-coupled with a vertical coaxial pipe 14. Most parts of the main axis 15 on a center side pierce through the long vertical coaxial pipe 14, and on the lower end side of the main axis 15, a coaxial pipe-rectangular coaxial pipe solid conversion circuit is provided, and it is feed-coupled with the horizontal rectangular waveguide 6.</p> |
