摘要: 根據(jù)實(shí)測的單元天線方向圖,利用幾何繞射理論,給出了金屬截錐柱側(cè)天線三維輻射場的一種有效的數(shù)值分析方法。這些公式同樣適用于金屬截柱或截錐。應(yīng)用上述公式計(jì)算了截錐側(cè)微帶天線及其排陣的任意平面方向圖,并與實(shí)測結(jié)果進(jìn)行了比較,兩者吻合良好。

Abstract: On the basis of the experimental element pattern and GTD, an efficient numerical method for analyzing 3-D radiation field of antennas on the truncated cone-cylinder is presented. These formulas are also applicable to the truncated cylinder and cone. Examples are given on the calculation of 3-D radiation fields of microstrip antennas on the truncated cone. The results of calculations agree well with the experimental ones. -
