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 provide an experimental verification. © 2008 Wiley Periodicals, Inc.
