Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>A novel hybrid resonant structure which can realize compact multiband bandpass filters (BPFs) and its design method are proposed in this article. The hybrid resonant structure is a dual‐plane structure which is an effective combination of a pair of microstrip stepped impedance resonators on the top layer and two nested dual‐mode defected ground structure resonators on the bottom layer. A triband BPF adopting this hybrid resonant structure was presented which was operating at 2.4/5.7 GHz (wireless local area network application) and 3.5 GHz (worldwide interoperability for microwave access application). The size of this filter is only 0.14<italic>λ</italic>₀ × 0.11<italic>λ</italic>₀. © 2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 24:690–696, 2014.</p> </abstract>
