1. An analyte sensor system, comprising:
an antenna array having at least three antennas each of which is configured to transmit and receive radio or microwave frequency electromagnetic waves;
electronic circuitry connected to the antenna array and controlling operation of the at least three antennas so that any one or more of the at least three antennas can be controlled to transmit a transmit signal in a radio or microwave frequency range into a target containing an analyte and so that any one or more of the at least three antennas can be controlled to detect a response in the radio or microwave frequency range resulting from transmission of the transmit signal into the target containing the analyte; and
the electronic circuitry includes at least one temperature sensor that detects a temperature of an element of the electronic circuitry;
wherein the electronic circuitry includes a signal generator, a radio frequency power detector, and an amplifier, and the at least one temperature sensor detects a temperature of the signal generator, the radio frequency power detector, or the amplifier.
