【摘要】 本文基于低频补偿TE M喇叭天线模型,根据天线口径阻抗公式,通过调整喇叭天线口径面的宽度来改变喇叭天线的口径阻抗,并对不同口径阻抗条件下喇叭天线的S₁₁参数,远场辐射波形和时域方向图进行对比,从而确定天线口径阻抗对喇叭天线特性的影响。更多还原

【Abstract】 In this paper,based on the low-frequency compensation TEM horn antenna model,according to the antenna aperture impedance formula,the aperture impedance of the horn antenna is changed by adjusting the width of the horn antenna aperture surface.The S₁₁ parameter,far-field radiation waveform and time-domain pattern of the horn antenna under different aperture impedance conditions are compared to determine the influence of the antenna aperture impedance on the characteristics of the horn antenna.更多还原
