This paper presents a helical resonator for measurement of complex permittivity of dielectric materials in form of thin sheets at 25 MHz. The indirect method of permittivity reconstruction is investigated. The full-wave 3D electromagnetic simulator is used to analyse the structure, create experiment model and build lookup database. The results of experiments are used to verify the possibility of accurate resonant measurement method at such low frequency.
