Abstract
A method of non-invasive detection of an analyte includes generating a transmit signal having at least two frequencies each of which is a radio or microwave frequency range of the electromagnetic spectrum, and transmitting the transmit signal into a target containing at least one analyte of interest using at least one transmit antenna/element. At least one receive antenna/element is used to detect response that results from transmitting the transmit signal by the at least one transmit antenna/element into the target containing the at least one analyte of interest. The at least one transmit antenna/element and the at least one receive antenna/element are less than 95% coupled to one another, or less than 90% coupled to one another, or less than 85% coupled to one another, or less than 75% coupled to one another.
