Impedances and Field Distributions of Two Coplanar Parallel Perfectly Conducting Strips with Arbitrary Widths.

Abstract

Transmission lines in the form of two coplanar parallel conducting strips with arbitrary widths are studied. This kind of coplanar strip line finds application in many aircraft antennas. The geometrical impedance factor, which relates the characteristic impedance of the transmission line to the intrinsic impedance of the medium surrounding the strips, is plotted and tabulated. The field distributions of the strips are also plotted. Compared to a two-cylinder transmission line with the radii of the cylinders being equal to the strip widths and the cylinders being separated by the same distance as the strips, the geometrical impedance factor of the strips is larger than that of the cylinders by approximately a constant (ln 2)/pi.
