IEEE. https://doi.org/10.1109/IMFW59690.2024.10477129979-8-3503-4532-210.1109/IMFW59690.2024.10477129https://academica-e.unavarra.es/handle/2454/51576In this paper, a design approach for effective low-pass filters (LPF) that use the Rth-passband replica of the stepped-impedance prototype response is presented. Traditional LPF design methods often rely on well-established techniques, but they may not always deliver the desired performance or flexibility. By incorporating the Rth-passband replica of the stepped-impedance prototype, we introduce a new perspective that opens up new possibilities in filter design. This approach has the potential to overcome some of the limitations associated with existing methods, offering improved filter performance, robustness, and novel design possibilities and flexibility. Additionally, we will showcase its practical application by designing, fabricating, and measuring a 5th-order gap waveguide LPF that employs the first replica as per the provided guidelines.application/pdfeng© 2024 IEEE.
