提出了一种分域求解法,解决了矩量法计算遇到的Sommerfield积分中Hankel函数奇异问题,实现了矩量法分析中全部阻抗矩阵元素的计算。采用三角面对基函数对圆柱分层介质上共形微带振子天线进行了理论分析。仿真验证了文中提出方法的有效性并分析研究了圆柱分层介质上z及φ方向共形微带振子天线的电磁特性,计算结果与对应平面情况进行了比较。
A solution to the problem of singularity of Hankel function in Sommerfield integral calculated by the method of moment is put forward to solve the singular problem of all impedance matrices in the method of moment analysis. A triangular face-basis function is used to analyze the conformal microstrip antenna on cylindrical layered media. Simulation shows the effectiveness of the proposed method and the electromagnetic properties of conformal microstrip antenna in z and φ directions on cylindrical layered media are analyzed. The calculated results are compared with those of the corresponding plane.
