Fuente: Wipo "Sensorization" A radio frequency (RF) magnetic sensor for magnetic field communication may comprise: a first RF magnetic sensor; a second RF magnetic sensor; a first inner protective case into which the first RF magnetic sensor is inserted and with which the first RF magnetic sensor is combined; a second inner protective case into which the second RF magnetic sensor is inserted and with which the second RF magnetic sensor is combined; a fixing jig in which the first inner protective case is coupled by penetrating in a first direction, and the second inner protective case is coupled by penetrating in a second direction perpendicular to the first direction; and an outer case for protecting the fixing jig by enclosing the fixing jig inside.
