Abstract
A high-frequency substrate in which a coplanar line including a signal line which transmits a signal and a pair of front ground patterns disposed in parallel with the signal line interposed therebetween is formed on one surface of a dielectric substrate, a back ground pattern is formed to cover the other surface of the dielectric substrate, and a plurality of conductive vias which connect the front ground patterns to the back ground pattern are arranged at a predetermined interval, the high-frequency substrate including: a signal line breaking portion which breaks the signal line; a substantially rectangular parallelepiped signal-line capacitor which is formed to connect the breaking ends of the signal line to each other; and ground pattern breaking portions which are disposed on both sides of the signal line breaking portion of the signal line to break the front ground patterns.
