Radio-frequency identification (RFID) is one of the many electromagnetic (EM) applications where WIPL-D software suite is successfully used. RFID assumes the wireless use of electromagnetic fields to transfer data, mostly for the purposes of automatic identification and tracking of various tags attached to target objects.
WIPL-D Pro as a method of Moments based code is very suitable for RFID. Most of the small and less complex tags are simulated in a few seconds. WIPL-D is extremely efficient for open radiating problems and especially for simulation of coupling between very distant objects (no boundary box requirement). WIPL-D Pro does not require to mesh the space between reader and the tag.
Part of the applications of WIPL-D software for devices marked as RFID include common industrial RFID tag (even winded around human wrist), complex RFID Reader at 13.56 MHz, multiband cross spiral tag, quadrifilar spiral antenna with circular polarization for UHF mobile RFID reader.
