A radio frequency identification device (100, 200, 300, 350, 400, 500, 700) includes a substrate member (110) having a first surface (109) and a second surface (111). Disposed on the first surface of the substrate member are a first antenna element (112) and a second antenna element (114). The first and second antenna elements are electrically isolated from each other and are coupled to two separate pads on an integrated circuit (116, 116'). The integrated circuit includes a power circuit (814) that produces a supply voltage for electronics on the integrated circuit in response to voltages coupled over the air to the pads on the integrated circuit via the first and second antenna element. Adhesive (118) is applied on the first surface of the substrate, the first and second antenna elements and the integrated circuit for securing the tag to a person or thing. |
