ANTENNA ARRAY FOR A NON-INVASIVE ANALYTE SENSOR
A detector array having a plurality of detector elements (also referred to as antennas) which have a minimum perimeter length and a maximum perimeter length. A detector array with detector elements having at least the minimum perimeter length has improved analyte detection performance compared to a detector array with detector elements that do not have the minimum perimeter length. In addition, a detector array with detector elements with a perimeter length no greater than the maximum perimeter length allows the size of the detector array to be minimized while still achieving the desired detection performance.
