Towards an RFID microsystem for surgical instrument detection using millimeter waves

Misplacement of surgical instruments inside an operating room is a frequent mistake that can bring unnecessary complications. We propose a system that can prevent these, through wireless communication. In this paper, we investigate the use of the 55-60 GHz band in the implementation of a RFID system that presents very interesting characteristics like improved security and small size. From the measurements already made, it's expected the RFID system operating in the 60 GHz ISM will work at distances, at least, up to 5 meters. Furthermore, it is proposed a solution to obtain a fully integrated system based on an on-chip antenna that could be integrated with an RF CMOS chip based on 65 nm CMOS technology.
