Abstract
First and second spaced apart, coextensive ground planes with a center conductor positioned therebetween in spaced relation from each of said planes and the volume defined by said planes being filled with a dielectric material fixedly engaging said planes and said center conductor to form a strip-line transmission line, the characteristic impedance of said transmission line being adjusted to a predetermined amount by forming a channel through one of said ground planes to the center conductor. The channel in the strip-line increases the characteristic impedance so that the width of the center conductor can be increased, for a specific characteristic impedance, to significantly improve control of the production of the strip-line.
