摘要
紧缩场低频应用的兴趣日益增加。本文是在面板大小一定的条件下,通过仿真计算探讨紧缩场在低频频段应用的可能性。电大尺寸紧缩场的快速仿真通常应用近场计算的卷积积分法。但是在低频情况下,这种方法的近似将会带来误差。本文通过有限积分方法(FIT)对紧缩场的低频特性进行计算,并通过这种精确离散化仿真计算结果与近似算法的比较,证明在一定情况下近似方法有它的适用范围。
Interests in low-frequency compact range increase nowadays. Application of compact range in low frequency is discussed in case of the fixed-size compact range plant. Convolution method of antenna near field calculation is adopted in simulation of compact range which is much larger than the relevant wavelength; however, inaccuracy is also brought. Performance of compact range in low frequency is simulated by FIT and applicable ranges of convolution method of antenna near field calculation are proved by the results.
