Printed radio frequency identification antennas

A method of forming a radio frequency identification (RFID) antenna comprising:

• forming an electrically conductive composition;
• forming, using the conductive composition, a loop element comprising a plurality of sides on a surface, the plurality of sides comprising a first side positioned opposite a second side;
• forming, using the conductive composition, a first conductive element and a second conductive element on the surface to be in electrical communication with and extending in opposite direction substantially from a middle portion of the first side;
• forming, using the conductive composition, a third conductive element and a fourth conductive element on to the surface to be in electrical communication with and extending in opposite direction substantially from a middle portion of the second side, the third conductive element formed to comprise an integrated circuit pad positioned distal to the second side;
• forming, using the conductive composition, a fifth conductive element on to the surface to extend from a first distal vertex of the second conductive element to a second distal vertex of the fourth conductive element;
• wherein
• forming one or more of the second conductive element and the fourth conductive element comprises forming one or more of the second conductive element and the fourth conductive element to comprise a quadrilateral shape;
• one or more of the second conductive element and the fourth conductive element is formed to comprise a width that is at least about the length of a side included in the plurality of sides;
• and
• the RFID antenna is formed to comprise an overall symmetrical structure.
