Abstract
A cut via is formed in an end of a multilayer circuit board of the first transmission line, and a clearance is provided between the cut via and a ground pattern for achieving an impedance matching between the first and second transmission lines. The cut via of a first transmission line which may be a stripline or a microstrip line, and an electrode of the second transmission line are connected to each other, and ground patterns of the first and second transmission lines are connected to each other. The first and second transmission lines have respective signal lines positioned substantially coaxially with each other.
