Disclosed is a microchip dual band antenna mounted to a printed circuit board having a ground surface and a non-ground surface. The carrier material has a conductivity below 10\u22126 Scm and is preferably electrically insulating. The circuit also includes a memory configured to store the first digital value in a first memory location that is mapped to a predefined and unique first address and to store the second digital value in a second memory location that is mapped to a predefined and unique second address.
