摘要
本文对作者正在研制的波导小室标准场装置作了详细的理论分析，包括其工作原理、设计方法及误差分析。当波导小室设计合理、匹配良好时，波导小室中传输行波，产生“准静态场”，可用作高频标准场，进行近场测试仪的校准，校准精度为±１ｄＢ。
狪n this paper, the theoretical analysis and design scheme are presented for the research and design of a standard field measuring system in which a waveguide chamber is used to generate the standard EM fields. As a waveguide chamber system has been well designed out and the impedances of each part match well, the wave in it is travelling wave. So a quasistatic calibrating field can be established in the waveguide chamber with an uncertainty of ±0.1dB.
