摘　　要：用解析公式对由圆波导TM01模激励的加平行板圆锥喇叭辐射场进行了分析,并采用有限元软件分析了该天线在不同频率的辐射场﹑反射系数。理论分析与实验结果表明,由圆波导TM01模激励的加平行板圆锥喇叭辐射轴向为极大值的线极化的远场方向图,在频率为5GHz时增益大于21dB,辐射效率约93～94%。Radition field of plate-conical horn excited by circular wavegnide TM01 mode is analysised by analytic formulations at first, Radition field and reflect coefficient are also calculated by using simulation software,theoretical analysis and experimental results show that the hom radiates linear polarized pattern with a boresight peak along the axis of the source, and geak gain of the hom is higher than 21 dB,radiation efficiency is about 93-94% at 5GHz.
