Abstract
An RFID tag includes a circuit board assembly having a circuit board, an RFID circuit, an antenna, and a metallic ground plane. The circuit board has a first side and a second side. The circuit board carries the antenna on the first side and the ground plane on the second side. The RFID circuit is coupled with each of the antenna and the ground plane. A backplane is coupled with the ground plane, on a side of the ground plane opposite the circuit board. An overmolded housing surrounds and hermetically seals the circuit board assembly. The housing is comprised of a material which is both autoclavable and has a low dielectric constant of between approximately 1 to 5.
