摘要: 本文用螺旋的半圓近似法計(jì)算了阿基米德螺旋天線的輻射場(chǎng)。應(yīng)用幾何繞射理論(GTD)導(dǎo)出了機(jī)載螺旋天線輻射場(chǎng)的計(jì)算公式。計(jì)算結(jié)果與實(shí)測(cè)結(jié)果進(jìn)行了比較,兩者吻合較好。

Abstract: The radiation fields of the Archimedean spiral antenna are derived by approximating the spiral with a series of semicircles. The formulas are developed to calculate radiation fields of the spiral antennas on an aircraft by applying the GTD. The calculated results agree well with the experimental ones. -
