Dielectric properties play an influential role in the development of medical devices. Understanding the behavior of these properties and how they respond to external stimuli, such as heat, over an extended frequency has yet to be researched. The focus of this study is to examine the impact of temperature on dielectric properties from 500 MHz to 10 GHz in order to better match the antenna properties of medical applications to the dielectric properties of biological tissue in question; more specifically, microwave ablation, microwave hyperthermia, and thermal modeling of brown adipose tissue’s metabolic processes. The dielectric properties of biological tissue samples from porcine lung, liver, heart, skin, fat, and muscle as well as brown adipose tissue and white adipose tissue from rat have been tested. These results have then been used to develop medical applications involving microwave antennas
