PURPOSE:To prevent the deterioration of transmitting characteristics due to the connecting part of a microstrip line when a high-frequency signal is transmitted using the micro-strip line. CONSTITUTION:When microstrip lines 3a and 3b are connected by bonding wire or gold ribbon 6, characteristic impedance of the connecting part of the bonding wire or the gold ribbon is matched by inserting high-dielectric constant rubber material 5. Therefore, high-frequency signal reflection generated at the connecting part is eliminated and the loss of the transmitting characteristics is prevented by matching the characteristic impedance of the bonding wire or the gold ribbon, which is provided between the connecting microstrip lines, with the impedance of the microstrip line. |
