Abstract :
A closed-form expression is presented for the effective dielectric constant of single microstrip lines which is valid with high accuracy up to mm-wave frequencies. The formula given has been designed for use in MIC and MMIC CAD programs as well as in the indirect measurement of substrate permittivities by resonance techniques.
