    摘要: A key unit that locks and unlocks a target by transmitting a signal to a locking and unlocking device, includes: a substrate on which a power supply circuit and a reception circuit that receives a request signal transmitted in a first frequency band from the locking and unlocking device via a reception antenna are mounted; and a housing configured to accommodate the substrate. Among parts associated with the power supply circuit, a part having the highest height from a substrate surface is mounted on a first surface of the substrate. The reception antenna is mounted on a second surface. When the substrate is accommodated in the housing, a distance from a substrate surface of the second surface to an inner surface of the housing is shorter than a distance from the substrate surface of the first surface to the inner surface of the housing.

    摘要: A wireless communication system includes: a locking and unlocking device configured to control locking and unlocking of a target, the locking and unlocking device including a device-side communication module configured to communicate a first signal having a first frequency band; and a key unit configured to command the locking and unlocking of the target by communicating with the locking and unlocking device. The key unit includes a unit-side communication module that communicates the first signal. The key unit is installed in the target such that a distance between the unit-side communication module and the device-side communication module is within a predetermined distance at which communication between the unit-side communication module and the device-side communication module is possible and that an axis of the unit-side antenna coil of the unit-side communication module is parallel to the axis of the device-side antenna coil.
