Abstract
The present invention provides electric circuits in which the line width of a conductor, which becomes close to a metal flange of a connector or a conductor wall, is gradually reduced from a predetermined position thereon, thereby the reduction of the impedance of the conductor line can be compensated.
Claims12
An electronic circuit comprising:
- a substrate made of a dielectric;
- a conductor line provided on the upper surface of said substrate;
- a connector connected to the end portion of said conductor line in the direction of signal propagation;
- and
- a conductor wall to which said connector is mounted;
- wherein the line width of said conductor line is gradually reduced to be smaller than the specific line width of said conductor line which is determined by a set impedance of said conductor line from a predetermined position as said conductor line becomes close to the said end portion.

An electronic circuit comprising:
- a substrate made of a dielectric;
- a conductor line provided on the upper surface of said substrate;
- and
- a conductor wall straddling said conductor line;
- wherein the line width of said conductor line is gradually reduced to be smaller than the specific line width of said conductor line which is determined by a set impedance of said conductor line from a predetermined position as said conductor line becomes close to said conductor wall and the portion of said conductor line which is straddled by said conductor wall has a constant line width.
