摘要: 为校准近场测量仪, 研制了波导小室来产生标准场.测试结果表明, 其场均匀性、 插入损耗以及中心工作区场强实测值与计算值的互差都符合要求.用并行打印口扩展板及相应的软件把计算机和数字外设相连, 建立起了波导小室标准场自动发生系统.

Abstract: Waveguide chambers are designed to calibrate electrical small antennas or probesof near field surveying instruments. Experiment shows the field established bywaveguide chambers is uniform and calculable, which is necessary to standard field. Via expansion board and software, computer and digital instruments are connected to be an automatic waveguide chamber standard field system.

Key words: electromagnetic theory, waveguide chamber, standardfield, impedance match
