1. A system for monitoring a health parameter in a person, the device comprising:
at least one transmit antenna configured to transmit radio waves over a three-dimensional (3D) space below a skin surface of a person;
multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves; and
means for isolating a signal from a particular location in the 3D space in response to receiving the radio waves on the multiple receive antennas and outputting a signal that corresponds to a health parameter of the person in response to the isolated signal;
wherein the at least one transmit antenna and the multiple receive antennas are configured for radio waves in a frequency range of 122-126 GHz, wherein the at least one transmit antenna is a patch antenna that has footprint dimensions of no more than 1.3 mm×1.3 mm and the multiple receive antennas are patch antennas that each have a footprint dimension of no more than 1.3 mm×1.3 mm; and
wherein the means for isolating the signal comprises a semiconductor substrate with a processor, at least one transmit component, and multiple receive components, wherein the at least one transmit component is collocated with the at least one transmit antenna and the multiple receive components are collocated with respective ones of the multiple receive antennas such that a portion of the multiple receive components overlaps from a plan view perspective a portion of the respective ones of the multiple receive antennas, and wherein the semiconductor substrate has a rectangular shape and the multiple receive antennas and the multiple receive components are collocated at opposite corners or opposite sides of the semiconductor substrate.
