Abstract

We have been presented the accurate complex permittivity method for small diameter dielectric rod samples using the 50GHz band TM₀₁₀ mode cavity resonator with small sample insertion holes. However, the measurement efficiency is not enough high to evaluate various samples due to the difficulty of sample insertion into the holes. In this paper, a novel insertion procedure for a small diameter dielectric sample is proposed using the insertion support tube to improve measurement efficiency. And, the suitable placement technique for the small dielectric sample is studied experimentally. Moreover, the complex permittivity of 4 kinds of 20 thermoplastic resin rods with a diameter of 0.4mm is measured efficiently and accurately around the 45GHz band.
