In this study, a wideband diplexer is proposed and the associated design concepts are also briefly discussed. First, two broadside-coupled bandpass filters are employed in the design phase so as to broaden the passband bandwidths of proposed diplexer. Next by adopting the stepped-impedance resonators in the design of the bandpass filter (BPF A) for the(More)
In this study, a new branch-line resonator is presented for dual-band filter design. By reducing one open stub of the conventional branch-line resonator, the filter structure will be simplified. Besides, since the external quality factor and center frequencies of two passbands can also be designed individually, the design procedure is therefore simplified.(More)
