提出一种融合曲线坐标和直角坐标的区域网格划分方法。在同轴线区域采用曲线坐标网格，用以代替传统的阶梯剖分，在其它区域及边界上采用直角坐标网格，从而极大地提高了计算效率。同时，在时域有限差分法中还采用了非均匀网格划分、PML吸收边界和Prony外推法等技术，对同轴馈电的耦合微带贴片天线进行了分析。

A method is proposed for the integrated use of conformal gridsand rectangular grids. In the coaxial line region, conformal grids are used instead of the classical staircasing method. In other regions and boundaries, rectangular grids are used. This greatly increased the calculation efficiency. Besides, the FDTD method with nonuniform orthogonal grids, extrapolation techniques and perfectly match layer (PML) are also applied to analyze a coaxial feeding coupled patch antenna.
