1. An analyte sensor, comprising:
a housing;
a sample chamber defined in the housing, the sample chamber is configured to receive a container at least partially therein that contains a sample;
at least one detector array mounted in the housing adjacent to and facing the sample chamber, the at least one detector array having two or more detector elements, at least one of the detector elements of the two or more detector elements is able to operate as a transmit element and at least one of the detector elements of the two or more detector elements is able to operate as a receive element, wherein the transmit element and the receive element are disposed on a substrate and are each located on a same side of the sample chamber;
the transmit element is positioned and arranged to transmit a signal that is in a radio or microwave frequency range of the electromagnetic spectrum into the sample chamber and into the sample contained in the container, and the receive element is positioned and arranged to detect a response resulting from transmission of the signal by the transmit element into the sample chamber and into the sample contained in the container;
a transmit circuit that is electrically connectable to the transmit element, the transmit circuit is configured to generate the signal to be transmitted by the transmit element; and
a receive circuit that is electrically connectable to the receive element, the receive circuit is configured to receive a response detected by the receive element.
