Abstract
A method of operation and system for a radio frequency identification (RFID) tag assembly having an RFID semiconductor chip with an antenna interface, a mounting surface substrate, the RFID semiconductor having a predetermined operating frequency, a conductor electrically coupling the RFID chip antenna interface to an antenna, the antenna including a first radiating element lying in a first plane and a second radiating element lying in a second plane, the second plane being at an angle relative to the first plane, and a reflector having a substantially planar reflecting plane spaced apart from and substantially parallel to the first plane, the reflector being composed of reflecting material adapted for reflecting the predetermined operating frequency, wherein the reflector is positioned apart from the first radiating element with the reflective plane being a distance of about ¼ of a wavelength of the predetermined operating frequency.
