A novel method for designing multiband bandpass filters has been proposed in this paper.
Coupling structures with both Chebyshev and quasi-elliptic frequency responses are …

A compact dual-band microstrip bandpass filter is proposed and designed to operate at 2.4
and 5.2 GHz without needing any external impedance-matching block. The modified half …

In this paper, open-loop resonators loaded by shunt open stubs are proposed to design
compact dual-band bandpass filters with improved out-of-band rejection characteristics. The …

The concept of the conventional coupling matrix is extended to include designs of dual-and
triple-band filters. The multiband response is created by either placing transmission zeros …

A microstrip bandpass filter using stepped-impedance resonators is designed in low-
temperature co-fired ceramic technology for dual-band applications at 2.4 and 5.2 GHz. New …

A class of stepped-impedance resonator (SIR) dual-band bandpass filter (BPF) with
selectivity-enhancement cells is reported. These dual-band filtering cells, which are …

Two types of modified open-or short-circuited stub-loaded λ/4 resonator and their
applications to second-order dual-band bandpass filters are presented in this letter. Based …

A new method for designing the multilayered filter, diplexer, and triplexer is proposed in this
paper. The main structure of the multilayered filter is a parallel-coupled line connected with a …

A new dual-band planar filter has been proposed. It is shown that the two transmission
bands can be excited and designed using proposed resonators which combine different …
