Modeling microstrip circuits and microstrip antennas on cylindrical substrates

1986 Antennas and Propagation Society International Symposium, 1986
The subject of modelling microstrip circuits and antennas on cylindrical substrates is considered. Two efficient methods are presented which overcome the heretofore existing convergence problems for the evaluation of near field quantities. The characterization of microstrip transmission lines, associated discontinuities and microstrip line fed ...

Surface Waves in Microstrip Circuits

6th European Microwave Conference, 1976, 1976
The launching of surface waves by discontinuities in microstrip circuits can cause extra coupling between adjacent devices. This paper gives measurements of the efficiency of an open circuit in microstrip to both launch and receive surface waves. The measurement technique is described in which the radiated waves from the open circuit are distinguished ...

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.

Equivalent Circuits of Microstrip Reflectarrays

IEEE International Workshop on Antenna Technology Small Antennas and Novel Metamaterials, 2006., 2006
Numerical research of scattering characteristics of printed reflectarrays with controllable loads is object of this paper. To calculate eigen values of a matrix of an equivalent superficial impedance tensor of microstrip impedance loads the empirical formula has been obtained.
