Beschreibung
Zusammenfassung:	A Radio Frequency Identification (RFID) tag arrangement is disclosed which is readable by an RFID tag reader placed in a listen only mode and is for actuating a downhole tool located in a wellbore. The RFID tag arrangement comprises a housing being non-metallic and a circuit board disposed in the housing. A transmission circuit is mounted on the circuit board and stores a payload. A transmitter coil is mounted on the circuit board and is disposed in electrical communication with the transmission circuit, the transmitter coil comprising multiple transmission antennas installed within the housing at multiple angles. An electrical power source is also mounted on the circuit board and is disposed in electrical communication with the transmission circuit, the electric power source storing an active charge before location in the wellbore. The electrical power source powers the transmission circuit to drive the transmitter coil to transmit the payload stored in the transmission circuit via the transmitter coil such that the RFID tag arrangement is actively readable by the RFID tag reader placed in the listen only mode external to the RFID tag arrangement.
