时域有限差分法（FDTD）的能力来计算辐射方向图，输入阻抗，和增益的一个导电盒上的微带天线被证明。结果给出了裸露的盒子，并与盒涂有介电层。辐射模式进行比较与测量，并与裸盒的矩量法。辐射模式的介质覆盖的盒子和所有的阻抗和增益的结果进行了比较，仅与测量。在所有情况下都取得了良好的一致性。FDTD方法很容易包括介质覆盖，而这对于矩量法方法来说是相当困难的。时域有限差分法计算单频结果所需的计算机时间与矩量法相似，但计算宽带阻抗和增益结果所需的计算机时间要少得多。>
The ability of the finite-difference-time-domain (FDTD) method to calculate radiation patterns, input impedance, and gain for a monopole antenna on a conducting box is demonstrated. Results are given for the bare box and with the box coated with a dielectric layer. Radiation patterns are compared with measurements and with the method of moments for the bare box. Radiation patterns for the dielectric-covered box and all impedance and gain results are compared with measurements only. Good agreement is obtained in all cases. The FDTD approach includes a dielectric covering quite easily, while this would be quite difficult for a method of moments approach. The FDTD method requires similar computer time as the method of moments for a single-frequency result, but produces wide-bandwidth impedance and gain results with much less computer time. >
