A microstrip line on a chiral substrate
IEEE Transactions on Microwave Theory and Techniques, 1991Right and left circular vector potentials are developed and used in a spectral-domain solution for a microstrip transmission line on a chiral substrate. These vector potentials have properties similar to those of the usual magnetic and electric vector potentials, except that they result in circular rather than linearly polarized fields, thereby ...

An investigation of losses in microstrip lines
2004 RF and Microwave Conference (IEEE Cat. No.04EX924), 2005This paper addresses the characterization of the sources of microstrip line losses by varying the surface roughness, loss tangent, dielectric constant and the height of the substrates. This is done by using simulations of microstrip line test circuits. Then, the test circuits are modeled using different type of substrates.

Multilayered Microstrip Transmission Line
2014There are a number of application areas of the terahertz (THz) spectrum which have been identified and discussed in Chap. 1. These potential areas can be categorized into the traditional and modern application areas. The traditional application areas are the imaging, sensing, and spectroscopy.

The Design of Coupled Microstrip Lines
IEEE Transactions on Microwave Theory and Techniques, 1975Although graphical results and formulas are available for the design of microstrip couplers, the design procedure is hampered because even- and odd-mode impedances are always expressed in terms of the physical geometry. In practice the designer obtains these impedances and then requires to know the geometry given by them.

Dispersion Characteristics of Microstrip Lines
IEEE Transactions on Microwave Theory and Techniques, 1981A coupled-line analysis is used in conjunction with Carlin's model in order to find the frequency dependence of the propagation constant and of the characteristic impedance of dispersive microstrip lines. The characteristic impedance of the coupled lines decreases with frequency.

1975 5th European Microwave Conference, 1975
The known design procedures for comb line filters are applicable only to filters using TEM-mode transmission line systems. Synthesis procedures for comb line filters using coupled microstrip transmission lines must take into account the unequality of the phase velocities of the fundamental modes on such a system. Such a method is presented.

Transmission-line Theory and Microstrips
1990Resistance, capacitance and inductance are the three main passive elements commonly used in circuits operating up to about 300 MHz, i.e. up to the lower end of the UHF band for various functions. High-frequency circuits from, say, a few tens of megahertz upwards, normally consist of a.c. and d.c. (bias circuit) paths.
