Abstract :
Different strategies have been suggested to improve the stop band of microwave lowpass filters and to suppress the spurious responses in the stop band. Resonance structures can be utilized in various microwave applications to improve the performance. In this article, a special form of a resonance structure is introduced which assists in achieving a deep stop band for microwave LP filters. Simulations are presented to support the usefulness of the structure suggested.
