| Abstract(in English) | A sapphire is expected as a good substrate for a low loss millimeter wave circuit such as a superconductor filter, because a good YBCO film can be manufactured on the substrate. In order to design millimeter wave circuits, it is neccessary to obtain the accurate complex permittivity. However, there are few reports of the complex permittivity for sapphire substrates in millimeter wave region. In this paper, the measured complex permittivity values of C-, A- ,R-plane sapphire substrates are presented and are discussed with the crystal structure. These values are measured using the cutoff circular waveguide method in the frequency range of 25-50GHz. |
