IEC 61338-1-4:2005 PDF

Scope: This part of IEC 61338 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. a) The dielectric rod resonator method excited by NRD-guide is similar to the dielectric rod resonator method given in IEC 61338-1-3. This method has the following characteristics: - a complete and exact mathematical solution of complex permittivity is given by computer software; - the measurement error is less than 0,3 % for s' and less than 0,05 x 10-4 for tan 8; - the applicable measuring ranges of complex permittivity for this method are as follows: frequency: 30 GHz
