Mounting bracket apparatus to amplify electromagnetic field strengths associated with mountable RFID tags are disclosed. An example apparatus includes a mounting bracket having a central portion, a first field amplification arm extending from the central portion in a first direction, a second field amplification arm extending from the central portion in a second direction different from the first direction, and a mounting arm extending from the central portion in a third direction different from the first direction and the second direction. The example apparatus further includes a radio frequency identification (RFID) tag mounted to the central portion of the mounting bracket.
