<P>PROBLEM TO BE SOLVED: To provide a small high frequency circuit by remarkably increasing a phase amount change at the time of passing a high frequency line in the high frequency line where high frequency signals of a microwave band and a milliwave band are transmitted, radiated, filtered, selected and amplified and the phase amount is controlled. <P>SOLUTION: Transmission regions 5 where convex-like projections 6 are disposed toward signal conductor wiring and transmission regions 4 where they are not disposed are repetitively set in a ground conductor 3 in a region facing signal conductor wiring 2 along an advancing direction. Thus, a pass phase amount per unit length, which is given to the transmitted high frequency signal, can be increased. Consequently, the high frequency circuit can be miniaturized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
