Abstract :
This paper therefore proposes for replacement of the conventional section of rectangular waveguide E-plane filter with the S-shaped resonator loaded waveguide structure, consist of a periodic cascade of metal septa. These structures while improving the stopband performance and compactness, maintain the low-cost and mass-producible characteristics of split-block E-plane technology.
