Claim 0:
1. A non-invasive analyte sensor device, comprising:
a sensor housing;
an antenna array attached to the sensor housing, the antenna array having at least one transmit antenna and at least one receive antenna, the at least one transmit antenna and the at least one receive antenna are configured to be arranged adjacent to a target containing at least one analyte of interest;
the at least one transmit antenna has a longitudinal axis, first and second ends, and first and second side edges;
the at least one receive antenna has a longitudinal axis, first and second ends, and first and second side edges;
the at least one transmit antenna and the at least one receive antenna are arranged side-by-side with the longitudinal axis of the at least one transmit antenna parallel to the longitudinal axis of the at least one receive antenna;
the at least one transmit antenna has a geometry that differs from a geometry of the at least one receive antenna;
the first and second side edges of the at least one transmit antenna are parallel to one another;
the first and second side edges of the at least one receive antenna are parallel to one another;
the at least one transmit antenna and the at least one receive antenna have a maximum spacing therebetween that does not exceed 50 mm and a minimum spacing therebetween that is at least 1.0 mm;
the at least one transmit antenna consists of a strip of conductive material;
the at least one receive antenna consists of a strip of conductive material;
a transmit circuit and a receive circuit disposed in the sensor housing;
the transmit circuit is electrically connectable to the at least one transmit antenna, the transmit circuit is configured to generate a transmit signal to be transmitted by the at least one transmit antenna, and the transmit signal is in a radio or microwave frequency range of the electromagnetic spectrum;
the receive circuit is electrically connectable to the at least one receive antenna, and the non-invasive analyte sensor device is configured so that the receive circuit receives a response detected by a single receive antenna of the at least one receive antenna resulting from transmission of the transmit signal by the at least one transmit antenna into the target containing the at least one analyte of interest.
