Making circuit elements out of transmission lines is most useful at microwave frequencies. At lower frequencies the longer wavelength makes these components too bulky. At the higher microwave frequencies planar transmission line formats are generally too lossy and waveguide is used instead. Waveguide, however, is
The microstrip characteristic impedance is denoted by Z ms, the ridged waveguide wave impedance is denoted by Z rwg, and the resistor Z r represents the radiation resistance. The short-circuited stub transmission line TL slot (characteristic impedance Z slot and the electrical length ?l slot) represents the aperture slot line.
Abstract: The characteristic impedance of a TEM transmission line, shaped as a double-ridged rectangular coaxial line, is analyzed in this paper as the customary transversal static problem. This type of transmission line is useful, for example, as a part of a cascaded transition between a double-ridged waveguide and a

This invention relates to apparatus for coupling microwave energy from a coaxial type transmission line to a double ridged waveguide transmission line and, more particularly, to a coax to waveguide transition which provides acceptable impedance matching between input and output transmission lines over a relatively

Still, the ridge gap waveguide is more advantageous for frequencies above 30 GHz, because it can be . height h, as long as we are able to realize a parallel-plate cut- off. .
