An original and simple approach to design electronically reconfigurable‐bandwidth
microwave planar bandpass filters is reported. It exploits the use of transversal signal …

In this paper, an exact synthesis and design procedure has been proposed for a class of
wideband dual-band bandpass filters (BPFs) with both controllable in-band ripple factor and …

A new class of microwave dual-band bandpass planar filter is reported. It uses an original
generalized branch-line hybrid topology devised here, operating as dual-passband …

This article presents a novel dual-band transmission line (TL), consisting of a multibranch
stub, which can provide equal unwrapped phases at two different frequencies. The …

In this paper, a novel dual-band active filter topology is presented. The non-linear phase
response of a composite right/left-handed cell is used to achieve the desired dual-band …

In this work, it is shown that it is possible to implement an unequal Wilkinson power divider
with reduced dimensions by using metamaterial transmission lines based on …

This work reports a planar signal-interference filter structure based on Bagley-polygon-type
four-port power dividers. It is shaped by the cascade of two identical transversal filtering …

This letter presents a novel recursive active filter topology that provides dual-band
performance, with independent tuning capability in both bands. The dual-band operation is …

ABSTRACT A novel two‐step algorithm to accurately analyze the transmission properties of
the transmission lines loaded with electrically small resonators is introduced. The algorithm …

Novel feedback signal interference concept for bandpass filter (BPF) design is proposed in
this thesis. This new concept was utilized to design wide stopband BPF with superior …
