The knowledge of temperature dependent dielectric properties of biological tissue in the microwave frequency range is crucial for medical applications such as microwave temperature monitoring during oncological treatments. This paper deals with temperature dependent dielectric spectroscopy of blood by means of ultra-wideband sensing. We present the results of relative permittivity and conductivity of blood without agents and blood with heparin in the frequency range of 0.5 GHz up to 7 GHz and in the temperature range between 30 °C and 50 °C. The measurements show that the addition of heparin does not affect the dielectric properties in the considered frequency and temperature range. Furthermore, the measurements are compatible with the few data reported in the literature.
