Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>This article proposes a compact filter using inductive coupled quarter‐wavelength resonators.The coupling between the quarter‐wavelength resonators is realized by a short‐end stub which behaves as a K‐inverter. As a result, the coupling coefficient of the resonators can be easily controlled by the length of the short‐end stub. A fourth‐order filter is designed and fabricated to demonstrate the proposed method. © 2013 Wiley Periodicals, Inc.
