提出了基于表面电流有限间隙馈电Halln型积分方程式分析较粗圆筒天线的数值方法。对于在脉冲展开点配矩量法的互阻抗表达式中遇到的特异点积分,介绍了一种数值结合解析法的处理方法,解决了特异点积分问题。该方法的主要优点是,在计算的简单性及节省计算时间方面要远远优于Galerkin法。实例天线输入阻抗的计算结果与其它方法的计算收敛值及测试值进行了比较。
A numerical method for the analysis of coarser cylindrical antennas based on Hall-n-type integral equations with finite gap feedforward of surface current is proposed. For the integral of integrals encountered in the transimpedance expression of the pulse-spread point method, a method of numerical combination analytic method is introduced to solve the problem of integral of specific points. The main advantage of this method is that it is far superior to the Galerkin method in terms of computational simplicity and computational savings. The calculated results of the antenna input impedance are compared with those calculated by other methods.
