| 摘 要： | 微带天线具有许多优点,在许多领域得到广泛应用。为精确设计微带天线,需了解描述天线性能的电参数。介绍了一种数值分析方法——时域有限差分法（FDTD）,从Maxwell旋度方程出发推导FDTD差分格式计算过程,总结出分析电磁问题的一般步骤,并采用FDTD分析了一款典型的微带天线。和电磁仿真软件XFDTD仿真结果相比较,可以看出FDTD计算结果与软件仿真结果吻合得很好。 |

| Abstract: | The microstrip antenna has a lot of merits,so it has been widely used in various fields.In order to design the microstrip antenna exactly,the electric parameters that describes the antenna performance are need to be comprehended.This paper introduces a kind of numerical value analysis method——finite-difference time-domain（FDTD） method,deduces the calculation course of FDTD difference format according to Maxwell rotation equations,and sums up the generic steps of analyzing electromagnetism problem,and uses FDTD to analyze a typical microstrip antenna.The result is compared with the simulation result of electromagnetism simulation software XFDTD,it can be seen that the calculation result of FDTD is consistent with the software simulation result. |
| Keywords: | microstrip antenna antenna electric parameter finite-difference time-domain method |
