Abstract

An electronic system includes a shared antenna, a diplexer and a processing circuit. The shared antenna corresponds to a first frequency band and a second frequency band, wherein the first frequency band meets a wireless radio frequency identification (RFID) standard, and the second frequency band meets a near field communication (NFC) standard. The diplexer receives a wireless signal from the shared antenna, and divides the signal into a WIRELESS RFID signal component corresponding to the first band and an NFC signal component corresponding to the second band. The processing circuit is coupled to the diplexer, and arranged to process the WIRELESS RFID signal component and the NFC signal component.
