A device for the non-invasive measurement of a glucose level, body hydration or another characterizing parameter of body tissue comprises at least two coplanar waveguides arranged on a common support. An AC signal is applied to the first ends of the coplanar waveguides, and the signal arriving at the second end is measured. The coplanar waveguides have differing gap widths, such that their electric fields have different reach into the body tissue. This allows obtain depth resolved information about the permittivities of individual tissue layers and to obtain more accurate results.
