High frequency signal line

摘要

The invention aims to provide a novel high frequency signal line not only adapted to eliminate an apprehension that the outer conductor and the directional coupling conductor might come in contact with each other and cause any malfunction but also adapted to facilitate a strength of branched output or leakage field to be adjusted depending on the particular requirement of operation. A transmission line consists of a central conductor and a cylindrical outer conductor formed with a longitudinal opening, the transmission line being covered with a cylindrical shielding shutter formed with a longitudinal opening, on one hand, and an induction line consists of a trough-shaped shielding cover formed with a longitudinal opening and adapted to be detachably attached to the shielding shutter and a directional coupling conductor for high frequency coupling which extends within the shielding cover in parallel to the central conductor. <IMAGE>
