Dual-Mode Microstrip Open-Loop Resonators and Filters

IEEE Transactions on Microwave Theory and Techniques, 2007
A miniature dual-mode microstrip open-loop resonator is proposed. Distinct characteristics of this new type of dual-mode resonator are investigated using full-wave electromagnetic simulations. It is shown that the two operating modes, i.e., the even and odd modes, within a single dual-mode resonator of this type do not couple.

Resonance characteristics of CPS open-loop resonator

2000 Asia-Pacific Microwave Conference. Proceedings (Cat. No.00TH8522), 2002
A novel coplanar stripline (CPS) open-loop resonator (OLR) is proposed for maximum miniaturization in uniplanar microwave applications. In addition, the effect of variation in the one's width of longer strips of OLR (namely, CPS fixed gap (FG) OLR) that is realized by cutting a gap into the one of the longer strips, oriented along the direction of ...

Resonance characteristics of capacitively loaded CPW open‐loop resonators

Microwave and Optical Technology Letters, 2003
AbstractCapacitively loaded coplanar waveguide (CPW) open‐loop resonators (OLRs) are proposed for maximum miniaturization in uniplanar microwave applications. It is shown that these resonators can be used to achieve a slow‐wave effect without occupying extra surface area.

A study on resonance characteristics of a microstrip open‐loop resonator

Microwave and Optical Technology Letters, 2001
AbstractA microstrip open‐loop resonator (MOLR) is proposed for maximum miniaturization in microwave applications, and to obtain a wider upper stopband including the first spurious resonance frequency for planar bandpass filters. The effect of variation in the width of one of the longer strips of an OLR formed in two ways (namely, fixed‐gap (FG) and ...

Dielectric Permittivity Sensor Based on Planar Open-Loop Resonator

IEEE Sensors Letters, 2021
Accurate characterization of the dielectric properties of solids and, especially, substrates is crucial for circuitry design and development. For applications requiring low cost, wieldy systems, many attempts have been made involving planar resonant microwave devices.

Microstrip slow-wave open-loop resonator filters

1997 IEEE MTT-S International Microwave Symposium Digest, 2002
Microstrip slow-wave open-loop resonators allow various filter configurations including those of elliptic or quasi-elliptic function response to be realised. The filters are not only compact in size due to the slow-wave effect, but also have a wider upper stopband resulting from the dispersion effects. These attractive features mean the microstrip slow-

Resonators in Open-Loop Sigma–Delta Modulators

IEEE Transactions on Circuits and Systems I: Regular Papers, 2009
In this paper, we introduce the modulo resonator for use in analog-to-digital open-loop sigma-delta modulators (OLSDMs). The OLSDM presented in this paper is intended for use in high-accuracy (14-bit) high-speed analog-to-digital converters. The modulo resonator is used with a modulo notch filter to insert a zero in the noise transfer function at a ...

An investigation on resonance characteristics of CPS open-loop resonator

APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002
A novel coplanar stripline (CPS) open-loop resonator (OLR) is proposed for maximum miniaturization in uniplanar microwave applications. The effect of variation in the width of longer strips of OLRs formed in two ways (namely, CPS fixed gap and CPS variable gap structures) on their resonance characteristics is discussed.

Open-Loop Resonance-Cancellation Control for a Base-Excited Pendulum

Journal of Vibration and Control, 2001
A new open-loop control strategy applied to a planar pendulum subjected to the most severe com bination of base excitations, horizontal motion at the primary-resonance frequency, and vertical motion at the principal-parametric resonance frequency is developed. The control action is typical of many single-input control systems; the control authority in

Open loop multi-resonator based chipless RFID tag

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
A simple, compact, planar open loop multi-resonator for chipless RFID tag with high quality factor is presented. It is a spectral signature based chipless RFID transponder. It consists of a set of cascaded open loop resonators. The prototype fabricated on a substrate of dielectric constant 3.7 and thickness 1.6mm is having an overall dimension of 28×13.
