Abstract

In this study, a patch resonator with two ports is proposed for retrieving the dielectric properties of biological tissues. The resonator is designed to operate in the 2.45 GHz Industrial, Scientific, and Medical band when placed on the tissue. CST Microwave Studio was used to simulate the structure with five layers of tissue above. Two via pins are used to tune the resonance frequency and to miniaturize the patch resonator. Rogers R03010 is used as a substrate. The configuration of the resonator and the simulation results are given. This paper also presents recipes of tissue-mimicking materials, along with dielectric property measurement results of fabricated physical tissue phantoms.
