本文分析了在“地面反射型测试场”上采用低架法测量椭圆极化天线的轴比时,由于地面反射波与直射波多径干涉而引起的测量误差,并提出消除地面反射波影响,从而提高测试精度的几种实际可行的方法。
This paper analyzes the measurement error caused by the interference of the ground reflected wave and the direct wave when the axial ratio of the elliptical polarized antenna is measured by the low shelf method in the “ground reflection type test field” and proposes to eliminate the influence of the ground reflected wave Several practical ways to improve test accuracy.
