Abstract
According to the embodiments described herein, a stretchable RFID device can include an RFID chip and an RFID antenna. The RFID antenna can be electrically coupled and mechanically attached to the RFID chip. The RFID antenna can be impedance matched to the RFID chip across a broad bandwidth and can include two arms. Each of the two arms can include an end-loading body that at least partially surrounds an end-loading orifice. The end-loading body can stretch without consuming the end-loading orifice.
