Abstract
Embodiments of the present invention relate to a symmetrical RFID antenna and method of formation. In one embodiment, the radio frequency identification antenna comprises a loop element having sides. A first and second conductive elements are in electrical communication with and extend opposite from a middle portion of a side. A third and fourth conductive elements are in electrical communication with and oppositely extend from a second side. A fifth conductive element extends from a vertex of the second conductive element to a vertex of the forth conductive element. The second and/or forth conductive elements comprise a quadrilateral portion. The second and/or forth conductive elements comprise a width that is at least about the length of a side included in the plurality of sides.
