中文摘要:
      介绍时域有限差分(FDTD)法计算准八木天线驻波比的算法实现方法。文中利用模型描述文件对天线进行了建模和网格划分;将各向异性完全匹配层(UPML)吸收边界分区编写,并利用区域的对称性简化了程序;采用带内阻的电压源作为激励源;最后从总电压中分离出入射电压和反射电压,得到了准八木天线的驻波比。实际制作了一个准八木天线并进行了测试,计算结果与实测结果基本一致,表明该实现方法是正确和有效的。
英文摘要:
      The Finite Difference Time Domain(FDTD) method was used to calculate the Voltage Standing Wave Ratio(VSWR) of a quasi-Yagi antenna. The model of the antenna was created and the mesh was generated by using model describing file. To simplify the calculating program, a Uniaxial anisotropic Perfectly Matched Layer(UPML) region was divided into six sub-regions and sub-regional symmetry was taken into account. The voltage source with lumped resistance was as excitation in the program. At last, VSWR was obtained by separating input voltage from total. A prototype quasi-Yagi antenna was fabricated and measured. The simulation result approximated to the measurement result, which proved the method had been correct.
