- 中文摘要: 本文以嚴密之理論分析內部自身匹配螺旋天線的輻射與極化特性,並提出天線輻射場數值分析的結果。文中對於螺旋天線繞線線圈圈距及相速度與輻射圖形、極化特性間的相關性做了探討與分析。 最後我們討論增加天線指向性的條件與天線性能的限制等等。
- 英文摘要: A rigorous theoretical treatment for studying the polarization properties and radiation characteristics of an internally matched helical antenna is presented. Numerical results for the radiated fields of the antenna are illustrated. The dependence of the radiation pattern and polarization on the turn spacing in the helix and the phase velocity of the wave traveling along the antenna is studied and analyzed. The conditions for the antenna with increased directivity and the limitations of antenna performance are also described.
