Nowadays, permittivity and permeability measurement are well-known in the industrial domain and research laboratory. It became unavoidable in few domains as biomedical and aeronautics. In this way, many researchers or engineers are committing to working on new measurement setup, complex or not working on a wide band of frequency. However, the thermal dependence of dielectric and magnetic structure is quite complicated to determinate, even though it became more and more important to know. As in the case of radomes antennas, the air friction produces increasing of temperature and thereby electromagnetic characteristics variation. Accordingly, we propose in this paper, a new characteristics measurement system of solid material between 100MHZ and 15GHz coupled to a high-temperature thermoregulation system designed to reach a few hundred degrees.
