Abstract :
The analysis and design of a variable cutoff frequency waveguide filter are presented. The filter, consisting of a low permittivity dielectric slab placed in a waveguide below cutoff, is designed to enable variation of the cutoff frequency up to 5% bandwidth. Measurements performed in the X-band and S-band agree with the theory.
