Abstract :
The conditions for and expressions of the best coupling flatness and optimum directivity obtainable over a given bandwidth from broad-wall aperture coupling between rectangular waveguides are derived. An inequality representing a constraining relationship among coupling flatness, directivity, and bandwidth is established.
