Abstract

1283148 Impedance matching INTERNATIONAL BUSINESS MACHINES CORP 4 March 1970 [21 March 1969] 10255/70 Heading HlW A transmission line system comprises a signal line 12 and a ground plane 11 preferably formed by a printed circuit technique on a dielectric layer 11 in which the signal line has a portion 15 of increased area, e.g. for connection of component leads, and the ground plane adjacent said portion 15 includes at least one aperture 16 to render the characteristic impedance uniform along the line 12. The aperture area is preferably substantially coextensive with the broadened portion of the line. Changes in the characteristic impedance of a transmission line due to capacitative coupling of a component device or to interboard connections may be substantially overcome by providing correctly oriented apertures.
