Abstract :
A wide scan quasi-optical frequency diplexer is required for certain antenna applications. A waveguide array is a structure which can fill this requirement and also discriminate proximal frequencies. The wide scan characteristics are enhanced by tilting the waveguide axes with respect to the waveguide-free-space interface. A variational analysis of this structure is presented, as well as experimental verification using a Ku-band model.
