摘要

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，详细推导了半波振子天线的 Pocklington 积分方程，利用分域三角基和伽辽金方法的矩量法求解Pocklington 积分方程，得到了半波振子天线上的电流分布，分析了对应的电场和磁场的分布情况，并简单介绍了半波阵子天线在电子药丸上实现无线通信及能量传输的应用。%Suitable for solving the differential equations and integral equations, Method of Moments is the discrete continuity equation into algebraic equations. Taking the half-wave dipole antenna as an example, detailed half-wave dipole antenna for the Pocklington integral equation is deduced, and the moment method to solve Pocklington integral equations by using the triangle basis and gamma Liaojin method and the current distribution half-wave dipole antenna were obtained. The distribution of the corresponding electric field and magnetic field are analyzed and the application of half wave dipole array antenna for wireless communication and energy transmission in electronic pill are introduced.
