半波振子天线矩量法的研究

矩量法是将连续方程离散为代数方程组的方法,此法对于求解微分方程和积分方程均适用,本文以半波振子天线为例,系统的阐述了半波振子天线的海伦积分方程的建立,利用矩量法求解海伦积分方程而得半波振子天线上的电流分布,已知电流分布求解半波振子天线在远区的电场表达式和方向图。

Research of moment methods on the half-wave dipole antenna

Moment methods is a way of separating continuity equation from algebra equation groups, it can be applied to the solution of both differential equation and the integral equation, this paper takes the half- wave dipole antenna as the example to expatiate sys- tematically the construction of Hallen integral equation based on half- wave dipole antenna, Hallen integral equation is solved by us- ing the moment methods to gain the current distribution of the half- wave dipole antenna, the expression and directional diagram of far field of half- wave diople antenna is solved by knowing current distribution .
