Abstract
A coaxial transmission line system includes a coaxial transmission line having a center conductor and an outer conductor, and an rf generator. A stub antenna is coupled to the generator, and extends radially into the transmission line between the outer and center conductors for capacitively coupling rf energy from the generator to the center conductor. Input impedance of the coaxial transmission line is matched to the impedance of the antenna and generator by means of a pair of tuning screws that extend radially into the transmission line between the outer and center conductors adjacent to the antenna. The tuning screws are adjustably positionable radially of the center conductor and are spaced from each other lengthwise of the transmission line.
