An original and simple approach to the design of fully reconfigurable multi-band microwave
bandpass filters (BPFs) with an arbitrary number of passbands is reported in this paper. It …

In this paper, a compact quad-band high-temperature superconducting (HTS) bandpass
filter using a quadruple-mode square ring loaded resonator (SRLR) is introduced. The even …

In this paper, miniature branch-line coupler and Butler matrix designs for 2.5-GHz
applications are proposed using the glass-based thin-film integrated passive device (TF …

Lossy signal-interference transversal filtering sections (TFSs) composed of two in-parallel
transmission-line segments with input-output matching lines-reflective-type part-and open …

In this paper, a compact filter based on substrate integrated coaxial line (SICL) stubs was
designed using an advanced multilayer printed circuit board (PCB) substrate. This …

A novel rotational angle microwave sensor with a high dynamic range and sensitivity for
detecting angular displacement is presented. It exploits the spectral separation between two …

In this letter, signal-interference filtering sections shaped by two in-parallel stepped-
impedance transmission lines are applied to frequency-asymmetrical microstrip filter design …

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 …

The design of planar sharp-rejection low-pass and bandpass filters (LPFs and BPFs)
featuring a very broad stopband is addressed in this paper. For the LPF case, two new …

The objective of this overview article is to report the latest research findings in the research
into RF/microwave reconfigurable-bandwidth bandpass planar filters with ultralarge …
