摘　　要：本文利用时域特征线算法(characteristic-based time domain method)计算了探针馈电圆柱共形微带天线的输入阻抗和辐射方向图。为减小数值计算误差,直接导出了圆柱坐标系下的相应控制方程,从而将三维方程转换为三个一维方程。计算结果与FDTD算法结果吻合良好,证明了本文理论与数值模型的可行性和精确性。Characteristic-based time domain method is employed to calculate the input impedance and the radiation pattern of a probe-fed cylindrically conformal microstrip antenna. To reduce the computational error, the governing equation in the cylindrical coordinate system is directly derived so as to reduce the three-dimensional equation to three one-dimensional ones. The numerical results agree well with those obtained by using FDTD, which verifies the feasibility and veracity of this method.
