• 中文摘要： 一行進波天線系統可被視為具有傳輸線之結構。因此，我們引入了一高電容值之均勻可變電容，來調整天線本身之阻抗，使直接匹配至外接之傳輸線特性阻抗，而形成一自身匹配之天線系統。詳細的理論模式及分析將在文中討論。
• 英文摘要： A traveling-wave antenna which has a slow wave section can be regarded as having a transmissionline structure. A uniform and variable capacitance large enough for matching tuning can be introducedin this antenna such that the impedance of the antenna can be tuned to that of the transmission line feedingit. Impedance matching of this antenna can be easily accomplished and maintained over a wide bandwidth.This matching arrangement results in a new type of self-matched traveling-wave antenna. Details of thetheoretical studies of such antennas are presented. A typical case is shown, where matching consideration,radiation characteristics, and radiation efficiency are given.
