Zusammenfassung:A RFID Reader includes a coupler housing and an antenna housing. The coupler housing further comprises a RFID transceiver and a coupling loop coupled to the RFID transceiver. The antenna housing comprises a passive loop antenna. The passive loop antenna is in close proximity to the coupling loop such that the passive loop antenna is coupled electromagnetically to the coupling loop and therefore the RFID transceiver can use the passive loop antenna for communication to a RFID device.
