标准摘要
[中文适用范围]: IEC 61338的这一部分描述了毫米波频率下介质谐振器材料介电性能的测量方法。本标准包括两种测量方法:a)NRD-guide(非辐射介质波导)激励的介质棒谐振器法和b)小环同轴电缆激励的截止波导法。 a) NRD-guide 激励的介质棒谐振器方法与 IEC 61338-1-3 中给出的介质棒谐振器方法类似。该方法具有以下特点: - 由计算机软件给出复介电常数完整、精确的数学解; - s' 的测量误差小于 0.3%,tan 8 的测量误差小于 0.05 x 10-4; - 本方法适用的复介电常数测量范围如下: 频率:30 GHz [外文原描述]: IEC 61338-1-4:2005-11(en-fr) describes the measurement method of dielectric properties for dielectric resonator materials at millimetre-wave frequency. This standard consists of two measurement methods: a) the dielectric rod resonator method excited by NRD-guide (Non-Radiative Dielectric waveguide) and b) the cut-off waveguide method excited by coaxial cables with small loops.
