Split Cylinder Resonator Temperature and Humidity Characteristics (28 GHz, MPI)

Overview

The dielectric constant of plastics, and in particular the loss tangent, varies greatly not only with temperature but also with humidity, and the extent of this change varies depending on the material. There is a growing demand to evaluate the permittivity under a specified temperature and humidity environment, particularly for applications that are expected to be used in high-humidity environments. Here, we evaluate MPI, which is relatively susceptible to humidity.
