Provided that the exact kernel is used, the application of simple and popular numerical methods to Hall?n-type integral equations for increasing numbers of basis functions (or points per wavelength) yields sequences of driving-point conductance and susceptance that can be extrapolated via properly selected convergence acceleration methods (CAMs). Such methods can lead to accurate final or converged results without the need for cumbersome and exhaustive runs or tests. Easy-to-apply CAMs are considered and highly accurate results are provided for the driving-point admittances of dipole antennas. The numerical results thus obtained are compared to well-known measured monopole admittances. These measured results are discussed in detail and some interpretations that allow a firm comparison are proposed. We thus combine good engineering practices (some of which are not novel) to obtain reliable theoretical values of drivingpoint admittance.

通过收敛加速方法获得的偶极导纳:快速准确的计算

如果使用精确的核,将简单而流行的数值方法应用于 Hall?n 型积分方程以增加基函数(或每个波长的点)的数量会产生驱动点电导和电纳的序列,这些序列可以通过正确选择收敛加速方法 (CAM)。这样的方法可以导致准确的最终或收敛的结果,而无需繁琐和详尽的运行或测试。考虑了易于应用的 CAM,并为偶极天线的驱动点导纳提供了高度准确的结果。将由此获得的数值结果与众所周知的测量单极导纳进行比较。详细讨论了这些测量结果,并提出了一些允许进行确切比较的解释。
