Claim Text:
1. A radio frequency identification (RFID) tag assembly comprising: an enclosure having a body with at least four walls defining an opening and a cavity with a closed end opposing the opening and defining a depth therebetween; an RFID chip assembly having a mounting substrate, an RFID semiconductor chip with an antenna assembly interface mounted on a mounting surface of the mounting substrate, the RFID semiconductor chip having a predetermined operating frequency, a conductor electrically coupled to the antenna assembly interface of the RFID semiconductor chip, and an antenna assembly electrically coupled to the conductor, the antenna assembly having one or more antenna elements with each antenna element coupled to the RFID semiconductor chip by the conductor and each antenna element including a first radiating element portion lying in a first plane that substantially lies in or is parallel to the same plane of a plane defined by of the mounting surface and a second radiating element portion conductively coupled to the first radiating element portion and lying in a second plane, the second plane being at an angle relative to the first plane of between 45 degrees and 135 degrees and in the direction away from the plane containing the mounting surface and towards the opening of the cavity, the mounting substrate with the RFID semiconductor chip being positioned within the cavity proximate to the closed end away from the opening; and a reflector positioned proximate to the opening of the cavity and having a substantially planar reflecting planar surface spaced apart from and substantially parallel to the first plane of the first radiating element, 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 portion at a distance of between about 0.250 inches and about 0.275 inches.
