Attenuation characteristics of coplanar waveguides

Abstract

The behaviour of attenuation losses in CPWs is studied for quasi planar transmission lines with constant characteristic impedance (Zo) and resistivity, having different geometries. Minimisation of loss for a chosen substrate thickness, conductivity and Zo is analysed. A sensitivity analysis for effective dielectric constant with respect to gap width, strip width,dielectric constant and substrate height, is presented 157 0-7803 -3619 -4

Investigation of the double-y balun for feeding pulsed antennas

“…WhileFig. 24provides us with a range of values for total attenuation in CPW lines, it is seen that the attenuation varies with the physical dimensions of the CPW line[26].…”
