Abstract
A microstrip line includes a signal strip conductor and a ground conductor. A coplanar line includes two regions. A first region includes a signal strip conductor which is connected to the signal strip conductor of the microstrip line via a wire or the like and a ground strip conductor which continues to the ground conductor. A second region is formed with a ground strip conductor formed above the ground strip conductor via a through hole. A transmission mode changes itself in the microstrip line, the first region of the coplanar line, and the second region of the coplanar line in the sequence as described. This enables converting the transmission mode efficiently from the microstrip line to the coplanar line.
