Abstract
In a high-frequency discharge apparatus utilizing a discharge tube positioned between an electrode and a ground plane, the electrode is shaped so as to increase the uniformity of the electric field across the discharge tube. Furthermore, a transmission line is formed between a conductor connected to the electrode and the ground plane, and impedance matching in the transmission line is provided by metal and/or dielectric tuning slugs inserted between the conductor and the ground plane.
