摘要
文中用半圆近似螺旋线,导出了阿基米德螺旋天线辐射场的计算公式,应用几何绕射理论(GTD),计算了带后腔的螺旋天线的辐射场,计算结果与实测结果进行了比较,两者吻合较好.
The radiation fields of the archimeds spiral antennaare derived by appoximating the spi-ral with a series of semicircles.Formulas are developed for calculating the radiation fields of thespiral antennas with back-cavity by applying the GTD.The calculated results agree well withthe experimental ones.
