An RFID tag includes a base having at least one fold formed therein. An integrated circuit is formed on the base. At least one antenna segment extends from the integrated circuit and crosses the fold. When the fold is creased, a portion of the antenna segment on one side of the fold is aligned to be orthogonal to a portion of the antenna segment on the other side of the fold.
