A dual resonance high frequency bandpass filter
This paper presents a design of dual resonance high frequency bandpass filter using Sonnet EM Simulator. Filter prototype is enhanced by adding the short stub in the center of the design. A parametric study shows the impact of choosing appropriate configuration characteristics. This is a dual resonance bandpass filter design, with center frequencies and . Performed input match at first resonance is and insertion loss is . The obtained results at second resonance are and . Due to its characteristics, this is a high-Q medium bandwidth dual resonance bandpass filter. The design is simulated and planning to be fabricated with 0.36 mm thickness and dielectric constant . This paper benefits from its compact size and simple geometry over the similar filters found in literature.
