摘要:

使用遗传算法优化设计了一种工作于S波段的平面波产生器.该平面波产生器是一个由25单元组成的线阵,它可以在距离其26~34个波长处产生各个切面幅度波动优于1dB、相位波动优于10°的静区,该静区尺寸为0.96m×0.18m×0.96m,其工作频率范围为2.2~2.8GHz.使用该平面波产生器测试时分长期演进通信标准的基站天线,可有效减小暗室面积,提高天线的测试精度.

Abstract:

Genetic Algorithm (GA)is applied to the design of an S-band plane wave generator(PWG). This PWG is a line array with 25 elements, which can generate a quiet zone with the size of 0.96m×0.18m×0.96m at the 26 to 34 wavelengths distance away from the array. The amplitude variation of this quiet zone at each section is less than 1dB, and the phase variation is less than 10 °. The work frequency range can reach 2.2~2.8GHz.This PWG can be used for time division long term evolution(TD-LTE) base station antenna measurements, with the chamber size effectively reduced and the test accuracy of AUT improved by the use of this PWG.
