Chipless RFID tag based on open-loop resonator
2017 IEEE Asia Pacific Microwave Conference (APMC), 2017A novel RFID tag employing open-loop resonators is presented in this paper. The resonators have been synthesized using coupled microstrip transmission line. The complete design consists of open-loop resonators based tag, and cross polarized circular patch antenna for transmitting and receiving purpose.

Hexagonal micropillar cavities: multimode resonances and open-loop resonance linewidth broadening
SPIE Proceedings, 2003We report our proof-of-principle experiment and modeling of hexagonal micro-pillar cavities. A commercial hexagonal silica fiber (125μm plane-to-plane) was side-coupled perpendicularly with a Gaussian beam, thus the fiber acted as a μ-pillar cavity. We observed multimode resonances with typical Q ≈ 2,500 in the tangential directions that are ≈ 120° to ...

The Broadside-coupled Microstrip Structure using Open Loop Resonator DGS
The 2014 International Symposium on Networks, Computers and Communications, 2014A novel design method of an ultra wideband (UWB) microstrip bandpass filter (BPF) based on The Broadside-coupled Microstrip and Open Loop Resonator defected ground structure (DGS) is presented. This filter provides in the passband an insertion loss of 0.3 dB and a return loss greater than 22 dB. In addition, the filter is compact size of 9.39×4.29mm 2

Isolation Enhancement of Patch Antenna Array Using Open Loop Resonator
2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018The paper presents isolation enhancement of 2 element array with rectangular patch antenna. Enhanced isolation is achieved by changing the array configuration and by introducing Open Loop Resonator(OLR) between the patches. The proposed array configuration provides an isolation of 25dB when the individual patches are kept at $\lambda/8$ distance with

A Dimmable Open-Loop Resonant LED Driver for a Horticulture Grow Light
TENCON 2018 - 2018 IEEE Region 10 Conference, 2018This paper presents an application of the LCC resonant converter as an LED driver in urban farming applications. A dimmable LED driver is needed to drive LEDs for a horticulture grow light. The LCC topology is chosen because of its capability to operate in open loop as a constant current source.

Electronically Reconfigurable Dual-ModeMicrostrip Open-Loop Resonator Filter
IEEE Microwave and Wireless Components Letters, 2008A new type of reconfigurable asymmetric frequency response bandpass filter using dual-mode open-loop resonator is investigated. It explores the unique characteristic of the dual-mode open-loop resonator whose two operating modes, i.e., the even- and odd-modes do not couple.

A compact open-loop resonator filter with a wide stopband response
AEU - International Journal of Electronics and Communications, 2007Abstract This paper presents a new class of microstrip slow-wave open-loop resonator filter with reduced size and improved stopband characteristics. A comprehensive treatment of both resonator ends loaded with triangular and rectangular shapes is described, leading to the invention of a microstrip slow-wave open-loop resonator.

The design of open-loop resonator HTSC linear-phase filter
Cryogenics, 2007The coupling gap between traditional open-loop microstrip resonators of high temperature superconductivity (HTSC) filter is too narrow to be fabricated with normal photolithography technology. The mixed couplings of HTSC open-loop microstrip resonators are studied in this paper and a new improved resonator structure that can be fabricated with normal ...

Microstrip band rejection filter using open loop resonator
Microwave and Optical Technology Letters, 2008AbstractDesign of a compact microstrip band reject filter is proposed. The device consists of an Open Loop Rectangular Resonator (OLRR) coupled to a microstrip line. The transmission line has a U‐bend which enhances the coupling with the OLRR element and reduces the size of the filter.
