| 摘 要： | 本文提出一个决定柱状天线电流分布的新的积分方程,这是一个一维的Fredholm第二类积分方程。它不同于天线理论中惯用的Hallen积分方程。本文着重分析了在天线为无穷长时,由两个方程所解得的电流和磁场,说明第二类积分方程比Hallen方程更适于描述天线的实际情况。还初步进行了有限长度天线的数值计算,结果表明用第二类积分方程进行天线的数值计算是可行的。

| Abstract: | A new integral equation for current distribution of a cylindrical antenna is de-rived. This is a one-dimensional Predholm equation of the second kind, and is different from the conventional Hallen equation in antenna theory. Emphasis is laid on the analysis of the current and magnetic field for an infinitely long antenna. It is found that our equation is more suitable for describing an actual antenna than the Hallen equation. Preliminary numerical computations for a finite antenna have been carried out. The results show that numerical computation using our equation is practical. |
