An RFID tag system includes a housing that includes an enclosed sidewall and forms a recess with a housing base surface, where the housing is configured and arranged to be mounted to a mounting surface. An RFID tag is located within the housing, and the RFID tag comprises an integrated circuit, an antenna and a metal backplane, where the housing base surface separates the antenna and the metal backplane. A metal surface is secured to a top surface of the sidewall to cover the recess, where the metal surface and a transmission path from the integrated circuit to the antenna are electromagnetically coupled and tuned to operate across a wide band frequency range. The metal surface may include a name plate of a data plate for a gas turbine engine, or a component thereof.
