    Abstract: An electronic key actively executes wireless communication following a keyless entry communication and passively executes wireless communication following a RFID communication. A vehicle control device is mounted on a vehicle and actively executes wireless communication following each of the keyless entry communication and RFID communication. An ECU/BCM unlocks a door by communicating with the electronic key using the keyless entry communication and issues a password to the electronic key in relation to this action. When a door knob or handle is pulled, an RFID-IC acquires the password issued by the ECU/BCM from the electronic key using the RFID communication and unlocks the door by authenticating the acquired password.

    Abstract: An electromagnetic-coupling module including a radio IC chip and a feeder circuit board on which the radio IC chip is mounted and a feeder circuit including a resonant circuit having a predetermined resonant frequency is attached to an article. The article has a radiation element that radiates a transmission signal supplied from the feeder circuit of the electromagnetic-coupling module via electromagnetic coupling and that supplies a received reception signal to the feeder circuit via the electromagnetic coupling.

    Abstract: A wireless communication device includes a wireless IC chip that processes a high-frequency signal and a feeding substrate including a coil conductor, a plane conductor, and a matching circuit that is connected to the wireless IC chip and that has a predetermined resonant frequency. The coil conductor and the plane conductor are connected to the matching circuit. The wireless communication device, when used by itself, operates as a monopole antenna in which the plane conductor functions as a ground and the coil conductor functions as a radiation element. When a conductive object is in a vicinity of the plane conductor, the plane conductor is coupled to the conductive object, and the wireless communication device operates as a dipole antenna in which the plane conductor and the conductive object function as a first radiation element and the coil conductor functions as a second radiation element.

    Abstract: An electronic key executes keyless entry communication or RFID communication. A wireless controller mounted on a vehicle executes keyless entry communication within a range of a radius of several meters to several tens of meters. An RFID reader is assigned to each door and executes RFID communication within a range of a radius of approximately 1 meter. In regards to unlocking the door, the wireless controller issues a password by the keyless entry communication, and a wireless circuit temporarily stores the issued password. The RFID readers search for the password stored in the electronic key by the RFID communication, and the wireless controller unlocks a door corresponding to the RFID reader for which the password was detected.
