Analysis of EM Characteristics of Koch Fractal Antenna Mounted on Complex Metal Objects

摘要: 基于电场积分方程的矩量法(EFIE-MoM),利用线面结点基函数(w ire-surface basis function)研究复杂金属载体上Koch分形天线的电磁特性,完成了数值方法的理论建模和程序实现。首先通过几种金属载体上普通单极子天线算例验证了理论模型和计算程序,接着计算了几种复杂金属载体上Koch分形天线的输入阻抗和远场方向性曲线,并对计算结果作了分析。

Abstract: On the basis of EFIE-MoM and wire-surface basis function,the EM characteristics of Koch fractal antenna mounted on complex metal objects are analyzed.Theoretical models and a computer program are verified by some examples of conventional monopole antennas on metal objects.The input impedance and radiation pattern of Koch fractal antenna mounted on complex metal objects are calculated.The obtained numerical results are analyzed and some conclusions are deduced.
