- 中文摘要: 利用一般化之傳輸線理論模式,本文推導出一槽孔耦合之柱面圓形微帶天線之等效電路。利用此一等效電路,天線之輸入阻抗可以很容易地被計算得到。在本文中,得到之理論結果也和測量值比較。同時,由結果可得知,此種天線之曲度大小與槽孔長度對天線之輸入阻抗影響極大。
- 英文摘要: An original equivalent circuit, based on the generalized transmission line model (GTLM) theory,is derived for the input impedance computation of a slot-coupled cylindrical-circular microstrip antennaThe theoretical results are compared with measurements, and the accuracy of the results is discussed. Boththe cylinder size and the coupling slot length are found to have significant effects on the input impedanceof the antenna.
