Abstract: A non-invasive analyte sensor system includes an antenna/detector array having at least one transmit antenna/element and at least one receive antenna/element, wherein the at least one transmit antenna/element and the at least one receive antenna/element are less than 95% coupled to one another, or less than 90% coupled to one another, or less than 85% coupled to one another, or less than 75% coupled to one another. The at least one transmit antenna/element transmits a transmit signal in a radio or microwave frequency range of the electromagnetic spectrum into a target containing an analyte of interest, and the at least one receive antenna/element detects a response resulting from transmission of the transmit signal by the at least one transmit antenna/element into the target.

Abstract: An automated medical diagnostic system includes antennas, transmitter, receiver, and a processor-based device or system. Excitations signals are transmitted into bodily tissue at each of a plurality of discrete frequencies (e.g., steps of 1 MHz from 300 MHz to 2500 MHz) or unequal steps. The response signals are received and analyzed against the excitation signals at each of a number of the frequencies, for example determining gain/loss due to passage through bodily tissue. The results are analyzed for patterns indicative of a presence or absence of an abnormal condition, and results presented.
