Embedded radio frequency identification (RFID) package

摘要

A radio frequency identification (RFID) device is described. In one or more implementations, the RFID device includes an integrated circuit (IC) die electrically connected to a radio frequency (RF) antenna winding for transmitting electronically stored information via the RF antenna winding. The RFID device also includes a substrate comprising a first core laminated to a second core. The RF antenna winding is routed through the first core and the second core. The first core defines a cavity for retaining the IC die. The cavity is disposed within the RF antenna winding in the first core.
