PURPOSE:To match the characteristic impedance over a broad band by mounting a conductive rubber into a gap between side walls opposite to each other of a couple of carriers. CONSTITUTION:A groove 55 is provided to a side wall 3A of one carrier 3 is provided in parallel closely with a ground conductor of a microstrip line and a conductive rubber rod 50 is press-fitted to the groove 55 and embedded therein so that the side face in the lengthwise direction of the opening of the groove is in press contact with a side wall 2A of the other carrier 2. Thus, a ground conductor connection path is formed by mounting the conductive rubber rod 50 with a length equal to the carrier width between the carriers 2 and 3 opposite to each other in this way and the ground conductor connection path is provided in a position close to a connection wire interconnecting strip conductors 25, 35. Thus, not only discontinuity in the characteristic impedance at a gap 10 is avoided but also the possibility of the production of an inductive component in the conductive rubber rod is precluded. Thus, the characteristic impedance over a broad band is matched. |
