Microstrip resonances in superconducting circuits

IEEE Transactions on Magnetics, 1987
Josephson junctions connected to high Q microstriplines display current-steps which we attribute to standing wave resonances. The step voltages of the resonances depend on sample geometry and correspond to frequencies at which the loaded microstrip is resonant.

NGD Analysis of Turtle-Shape Microstrip Circuit

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
A negative group delay (NGD) design of a turtle shape circuit topology is developed in this brief. The topology is comprised of two different length transmission lines (TLs) interconnecting two identical coupled lines (CLs). The S-matrix model is established as a function of the TL and CL parameters.

Microstrip circuits on micromachined silicon

Digest of Papers. 2004 Topical Meeting onSilicon Monolithic Integrated Circuits in RF Systems, 2004., 2004
Fully monolithic integration of a millimeter wave system on silicon requires low loss passive circuitry. Transmission line elements are needed to interconnect active devices and to realize distributed passive components. Using bulk micromachining and high resistivity silicon on insulator (SOI) wafers, well defined thin silicon membranes can be ...

Radiation from microstrip circuits: An introduction

International Journal of Microwave and Millimeter-Wave Computer-Aided Engineering, 1991
AbstractMicrostrips are open structures, that tend to radiate as the frequency of the signal increases within the microwave range. Radiation becomes significant in the vicinity of discontinuities, particularly when parts of the structure resonate. This situation is encountered in the design of filters, which often are arrays of radiating dipoles.

On Circuits with Coupled Thick Microstrips

16th European Microwave Conference, 1986, 1986
A method for calculation af coupled thick microstrip parameters is presented. The method is employed in analysis- and synthesis procedures (programs) for circuits with multiple coupled strips with arbitrary dimensions on arbitrary isotropic substrates. It is thus possible to analyze and synthesize e.g.

Optimization of aperture transitions for multiport microstrip circuits

IEEE Transactions on Microwave Theory and Techniques, 1996
The introduction of the printed aperture into multiport microstrip circuits as a vertical transition proves to be practical in the design as well as the manufacturing process of multilayered circuits. With the mixed-potential integral equation-based moment method, it becomes possible to analyze and optimize the performance of this arbitrary shape ...

Frequency Downconverters using Microstrip Circuit

IETE Journal of Research, 1971
In this paper an attempt is made to present the work on microwave frequency downconverter using microstrip circuit, that is being carried out at Himalayan Radio Propagation Unit. The L- and S-band frequency downconverters make use of 3 db branch line couplers and Schottky barrier diodes as mixing elements. The isolation between local oscillator and the

Noncontacting measurement of power in microstrip circuits

2006 67th ARFTG Conference, 2006
This paper describes the use of a loop coupler probe for noncontacting measurement of power in microstrip circuits. The additional uncertainties, compared to contacting measurements, are investigated. The sensitivity of the coupling to positioning errors gives an uncertainty contribution in the same order as when using galvanically contacting ...

Modelling SMD capacitor for microstrip circuits

Proceedings. Electrotechnical Conference Integrating Research, Industry and Education in Energy and Communication Engineering', 2003
Simple models and a parameter extraction technique for low-cost SMD capacitors mounted on microstrip lines are presented. The models are simple networks, easily implemented in currently available microwave CAD (computer-aided design) programs. Their element values are obtained from the results of vector network analyzer measurements on microstrip ...
