Abstract:
1. An electronic system comprising: a shared antenna, corresponding 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; a diplexer, coupled to the shared antenna, and comprising an input end, a first output end and a second output end, wherein the input end of the diplexer is used to receive a receiving signal from the shared antenna, the diplexer transmits a wireless RFID signal component of the receiving signal corresponding to the first band to the first output end of the diplexer, and transmits an NFC signal component of the receiving signal corresponding to the second band to the second output end; and a processing circuit, coupled to the diplexer, and arranged to process the wireless RFID signal component when receiving the wireless RFID signal component, and to process the NFC signal component when receiving the NFC signal component.
