摘　　要：本文利用矩量法分析计算套筒天线 .文中采用一种新的粗圆柱线天线快速精确计算模型 ,提出了所谓的“等长分段”方法 ,并使用了一种固定间隔电压源模型 ,大大提高了分析计算的精度 ;通过使用正弦插值基函数、引入Daubechies小波变换等 ,提高了分析计算的速度 .最后 ,设计制作了一付工作在 2 0 0 - 70 0MHz频段、VSWR≤ 3.0的实用套筒天线 ,其分析计算结果与实验结果相吻合 .In this paper,the method of moments is used to compute sleeve monopole antennas.A new efficient and accurate modeling for moderately thick cylindrical wire antennas with a so called ‘equal length dividing method’ and a constant gap voltage source model is established to greatly improved the accuracy.By using the sinusoidal interpolate basis and Daubechies discrete wavelet transform,the computing time is considerably reduced.Finally,a practical sleeve antenna,with the VSWR less than 3 0 in 200～700MHz frequency band,is designed.The calculated results of these three antennas are all in good agreement with the experimental results.
