Variation of microstrip losses with thickness of strip

The attenuation in microstrip lines has been calculated by relating the longitudinal components of current to the charge profiles of a static solution. The calculation has been performed for varying thicknesses of strip to examine the mechanism of loss for very thin strips, where the penetrating fields from both surfaces of the strip overlap. The results are presented in the form of a universal loss curve for the particular geometries studied, indicating the minimum thickness of strip to be used to advantage.
