A new analytic design for multilayer stripline devices in planar circuit technology is
presented. The Complementary Split Ring Resonator (CSRR) is used as a sub-wavelength …

This article presents a novel concept for a tiny stepped impedance resonator (SIR) to ease
the application of bandpass filters. In recent years, its significance has expanded due to the …

In this paper, we proposed a compact C-open-loop ring resonator and its equivalent circuit.
The second cascaded BSF are designed using this simple C-ring resonator. The double ring …

The advent of context-aware environments and related applications demands a high degree
of connectivity, with new spectral bands and related radio resource management …

This paper presents a new type of a negative coupling structure for designing elliptic-
response filters with cross-coupling. The proposed coupling structure consists of short …

This study presents a microwave planar sensor for characterisation of powdered foods. The
sensor is based on four coupled resonators designed to have four poles in the frequency …

This article studies a filter belonging to the category of bandpass filters. This filter has two
resonators located on the substrate with dielectric conductivity ε= 4.4 and thickness h= 1.5 …

A novel design of microstrip bandpass filter with two spiral resonators is presented in this
paper. The proposed filter has good frequency selectivity and its dimensions are smaller in …

In this paper, we proposed several compact bandstop filters using C-open-loop ring
topology. In the first step a minimize bandstop using single C-ring resonator is simulated …

The designs of compact microstrip band-pass filters on identical U-shaped resonators are
proposed. These resonators are located on a completely metallized substrate surface. The …
