Abstract

An analyte sensor that detects an analyte via spectroscopic techniques using frequencies in the radio or microwave frequency range of the electromagnetic spectrum. The analyte sensor is configured to permit adjustment of the position(s) of one or more transmit components and/or the position(s) of one or more receive components. Adjusting position (or the like) as used in the description and claims includes changing an angle of the transmit component(s) and/or the receive component(s), and/or moving the transmit component(s) and/or the receive component(s) in one or more X, Y, Z directions, and/or changing a shape of the transmit component(s) and/or the receive component(s), and any combinations thereof.
