Abstract (in Japanese) (See Japanese page) 
(in English) The cavity resonator method, which has standardized in the JIS standard and the IEC standard, is one of measuring method for the complex permittivity in the horizontal direction of dielectric substrate in microwave region. However, in V band, its excitation holes are too big, compared as the standardized cavity dimensions. Therefore, it is difficult to apply this method in V band or more, because the resonant electromagnetic field is affected significantly by the excitation holes. In this paper, 55GHz cavity resonator suitable for cavity resonator method was developed in considering the effect of the excitation holes. Moreover, the complex permittivities of a PTFE plate were measured using fabricated two cavity resonators. As a result, it is verified the developed cavity resonator is useful for the cavity resonator method.
