APPARATUS FOR NON-INVASIVELY DETERMINING DEEP TISSUE TEMPERATURE USING MICROWAVE RADIOMETRY

Abstract

The present disclosure provides a sensor assembly for non-invasive temperature measurement using microwave radiometry. The assembly comprises a circuit board with a thermistor, capacitor, and inductor, where the inductor electrically isolates microwave signals from temperature sensing signals. A coaxial connector is positioned at one end of the circuit board with an antenna aperture at the opposite end. A shield layer extends over the circuit board with a sensor region, transition region, and extended region that are offset from the circuit board components. The shield layer is oriented at an angle relative to the circuit board. The inductor utilizes parasitic capacitance to improve antenna impedance matching, while the capacitor provides microwave signal isolation for the thermistor to prevent interference with signal detection.
