| 摘 要： | 本文利用矩量法分析任意形状导体地面上的线栅型圆锥单极子天线.文中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.最后,以圆形和方形地面为例,分析了一副400MHz~2100MHz的圆锥单极子天线,其数值计算结果与实验结果吻合良好,表明了有限地面对天线阻抗匹配的重要性和本文方法的有效性.

| Abstract: | Wire conical monopole antennas at an arbitrarily conducting ground plane are analyzed by the Method of Moment (MM).The basis function presented by RWG is used to present the current on the surfaces.The triangular basis function is used to present the current on the wires,and a special basis function is used to present the current on the wire/surface junctions.Finally,as an example,conical antennas on a circular and a square ground plane in 400MHz~2100MHz frequency band are analyzed respectively.Numerical results and comparisons show the efficiency of the method and the finite ground plane plays an important role in adjusting the impedance matching. |
