借助Maxwell方程组,将时域有限差分法应用于实验室研制的新型层叠式微机械微带贴片天线的建模和分析,并根据数值模拟结果讨论了天线的特性参数。根据实际情况,灵活地给出了各边界的近似吸收边界条件,有效地减少了存储空间和计算时间。
With the help of Maxwell’s equations, the finite difference time domain method was applied to the modeling and analysis of the new laminated micromechanical microstrip patch antenna developed in the laboratory. According to the numerical simulation results, the characteristic parameters of the antenna were discussed. According to the actual situation, the boundary condition of approximate absorption boundary is given flexibly, which effectively reduces the storage space and calculation time.
