摘　　要：利用矩量法分析任意形状导体地面上的套筒单极子天线。对面结构选用三角形面元矢量基函数 ,对细线结构选用三角基函数 ,对线面结合处采用一种特殊的基函数 ,将导体地面和天线作为整体进行分析 ,大大提高了分析计算的精度。分别分析了两付位于圆形和方形地面上的实用套筒天线 ,其数值计算结果与实验结果或软件模拟结果吻合良好 。The sleeve monopole antennas at an arbitrary conducting ground plane are analyzed by the method of moment (MoM). The RWG basis function and triangular basis function are chosen to discretizated the conduting ground plane and thin wire, respectively, and a special basis function is used to represent the current on the wire/ground-plane junctions. The numerical results of two practical sleeve antennas located respectively at circular and square ground plane are compared with the measured data to prove validity of the analysis method.
