摘要:

移动通信基站天线测试场地存在的反射波会对天线测试产生较为严重的影响。反射波与直射波的时差和反射点位置、天线长度等因素有关。文中分析了典型测试条件下反射波的反射路径,计算了反射波与直达波的时延差,根据天线测试指标的要求给出了采用时域分割降低放射波影响的测量方法。理论分析和实际测试表明,该方法能有效降低测试场地中大于规定值的反射,更为客观地反映基站天线本身的技术指标,保证被测天线的测量精度。

Abstract:

Testing results of mobile communication base station antenna index are serious impacted by reflected wave.The time difference of the reflected wave and the direct wave is related to the location of the reflection point,the antenna length and other factors.The time difference is computed,and a time-domain method is proposed for the elimination of the reflection of the test site of greater value than the specified one.Theoretic analysis and real testing show that the method can lessen the influence of the reflected wave effectively with more accurate testing indexes.

Key words: time-domain method;direct wave;reflected wave;antenna testing
