1. A transducer for noninvasively measuring temperature within a body of a subject, comprising:

  • a circuit board including a front side and a back side opposite from the front side, the circuit board defining an antenna for receiving at least one native temperature signal from a location of interest within a body of a subject;

    a receiving aperture adjacent to the front side of the circuit board;

    an adhesive material adjacent to the front side of the circuit board and configured to secure the circuit board to the subject;

    a dielectric cavity adjacent to the back side of the circuit board, the dielectric cavity including an inner extent adjacent to the back side of the circuit board and an outer extent opposite from the inner extent, the dielectric cavity configured to conduct radiofrequency currents to the receiving aperture; and

    at least one shielding feature positioned adjacent to an outer extent of the dielectric cavity to prevent interfering signals from impinging upon at least the back side of the circuit board.
