What is an ID-1 PICC Antenna?
ISO/IEC 7810 defines the mechanical requirements for plastic identification cards, including smartcards. The nominal
ID-1 card dimensions are 85.6 mm by 53.98 mm, and 0.76 mm thick. There are no antenna dimension requirements in
ISO/IEC 7810.
Typical antenna dimensions for ID-1 PICCs are described in ISO/IEC 10373-6 section 6.3 as a “Reference PICC”
antenna. The outer dimensions of this reference antenna are 72 mm x 42 mm with four concentric turns. The antenna
trace width and spacing are both 0.5 mm with a tolerance of +/- 20 %. This is a test antenna; the number of turns
required on a real antenna may be more or less than four turns.
Additional guidance regarding ID-1 PICC antenna dimensions is provided in Amendment 4 to ISO/IEC 10373-6 in the
form of a “Class 1” PICC antenna definition. A “Class 1” PICC has its antenna located entirely within a zone defined by
two rectangles centered in the ID-1 dimensions. The external rectangle is 81 mm by 49 mm. The internal rectangle is
64 mm x 34 mm, with a 3 mm corner radius. All antenna turns must be located between these rectangles.
Any antenna falling within the “Class 1” dimensions is considered an ID-1 antenna for the purpose of this specification.
Other Characteristics Impacting Performance
The ISO/IEC 14443 standards do not guarantee that any compliant PCD will operate with any compliant PICC. A
reliable RFID system uses PICCs and PCDs matched to the application, with appropriately sized antennas. Discussion
of the numerous factors impacting the performance of RFID systems is beyond the scope of this document.
