    Abstract: 矩量法已成功用於各種電磁問題中,如實用性之線狀天線的輻射,此
    法能夠將線上未知電流分佈轉換成有限個未知數,並將相關之積分方程式近
    似成聯立線性代數方程式系統。 帕克林敦積分方程式,可算是處理線狀天
    線時最常用的形式之一。此積分方程式,雖適用於各種形式之輸入源,但仍
    被限制在僅有軸向電流存在時之情況。
    計畫中探討線狀雙極天線的半徑沿著軸長變化時對天線的影響,如果非
    軸向電流可忽略時,採用矩量法求解帕克林敦方程式,進而求出線上電流分
    佈。反之,無法忽略時,計畫中將需要發展新的積分方程式形式以求解電流
    分佈。求出電流分佈後,可據而分析各項輻射特性與天線參數。
