A compact quasi-elliptic bandpass filter using coupled dual quasi-lumped LC resonators

This letter proposes a compact microstrip bandpass filter using coupled dual quasi‐lumped LC resonators. With the proposed topology, two transmission zeros are generated at both low and high stopband near the passband to create quasi‐elliptic response. A filter sample is designed and fabricated to p...

Zusammenfassung:This letter proposes a compact microstrip bandpass filter using coupled dual quasi‐lumped LC resonators. With the proposed topology, two transmission zeros are generated at both low and high stopband near the passband to create quasi‐elliptic response. A filter sample is designed and fabricated to provide an experimental verification. © 2008 Wiley Periodicals, Inc.
