要約(日本語): Dielectric materials for outdoor wireless devices such as a connected car, IoT sensor for a road are required to have a good mechanical characteristic and to be low cost. Engineering plastics and glass materials are known as superior properties with weather, heat, impact resistances and low cost. However, there are few reports for frequency dependence of complex permittivity in the frequency band for 5G/6G communication system. In this paper, complex permittivity measurements of eight kinds of dielectric materials which are expected for application of smart mobility are performed by the cut-off circular waveguide method in the frequency range of 30 GHz to 100 GHz at room temperature. As a result, relative permittivity for the measurement samples does not have frequency dependence and loss tangent are slightly increasing or almost constant as frequency increase in the measured frequency range. We expect these measured results can be useful to develop reliable IoT sensor & 5G/6G devices for "Smart Mobility".
