Abstract

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.

Key words: plane wave, antenna measurements, antenna array, genetic algorithm(GA), time division long term evolution(TD-LTE) base station antenna
