Multi-loop Control Using Gershgorin and Ostrowski Bands

Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014
The goal of this paper is to develop a new method of decentralized control tuning. This method is based on Nyquist-Arrays and independently designs monovariable controllers for each loop of the plant while ensuring the robust stability of the multivariable system.

Clinical success and longevity of band and loop compared to crown and loop space maintainers

European Archives of Paediatric Dentistry, 2015
To prospectively evaluate the success and survival rates of band and loop (B&L) compared to crown and loop (C&L) space maintainers.Thirty-six children were divided into two groups (18 B&Ls and 18 C&Ls) matched for gender, age and the extracted tooth. For the study group, all clinical procedures were performed by the same paediatric dentist.

Compact Dual-band and Tri-band Filters with Loaded Open-loop Resonators

Journal of Electromagnetic Waves and Applications, 2007
A novel design method of dual-band and tri-band band-pass filters is proposed in this paper. A compact loaded open-loop resonator(LOLR) structure is introduced. The resonant frequency response of the resonator is described in detail. A dual-band filter and a tri-band filter are designed with the LOLRs.

Ultra-Compact Band-Pass and Band-Stop Tunable Filters Based on Loop-Cascaded Nanobeam Structure

IEEE Photonics Technology Letters, 2021
We propose an ultra-compact band-pass and band-stop filter with bandwidth tunability based on the loop-cascaded nanobeam structure in simulation, with a small coupling region of $41\times 1\,\,\mu \text{m}^{2}$ . It features low insertion loss, large bandwidth tunable range and high sidelobe suppression ratio. By two-stage cascading, the bandwidth

Miniaturized triple-band USB dongle antenna using loaded-fractal loop monopole with shorted loop and fractal loop resonator

2012 9th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2012
By coupling a fractal loop resonator onto the back of a loaded-fractal loop monopole and a shorted loop, a new triple-band USB dongle antenna has been achieved and presented. The proposed antenna supports WLAN (2.4–2.5 GHz and 5.15–5.875 GHz) and WiMAX (3.4–3.6 GHz) applications. Omnidirectional radiation patterns for the three bands are observed.

A 12.5Gbps Dual Loop CDR with Multi-band VCO and Novel Frequency Band Switch

2018 14th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT), 2018
A novel 12.5Gbps quarter rate CDR is presented in this paper. For lock acquisition depends on the frequency tracking loop (FLL loop) and recovered clock jitter depends on the phase tracking loop (PLL loop) without one impacting the other, the CDR gets both short lock acquisition and low clock jitter.

Dual-mode dual-band microstrip square loop resonators and filters

2008 Asia-Pacific Microwave Conference, 2008
DMDBFs were proposed for miniaturization and asymmetric frequency characteristic. The consisting of two DMRs based on microstrip square loop resonators was fed by a common T-shaped nonorthogonal I/O feed lines located on the horizontal symmetry axis.

Multi-frequency and wide-band VSWR characteristics of loop antennas

IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002
Typically, loop antennas are constructed from a single wire and have a round or square shape. Antennas with more than two loops located in the same plane have been investigated, but a more detailed investigation of such multi-loop (ML) antennas is required for design purposes. This paper presents a theoretical investigation of two types of loop antenna

Loop‐loaded monopole antenna with miniaturization and dual‐band characteristics

Microwave and Optical Technology Letters, 2012
AbstractA novel miniaturized dual‐band monopole antenna loaded with two types of loops is presented. The split loop is loaded at the center of the monopole for dual‐band operation and the rectangular loop loaded at the top is for miniaturization. The novel miniaturization technique is used as a self resonant topology.
