A method for localizing a user device using a Time-of-Flight (ToF) antenna array disposed on a vehicle, the method includes determining via a ToF localization controller, that a user device is positioned at a front region of a vehicle, calculating a distance to the user device from a combination of two ToF antennae of the ToF antenna array, and performing a 2-dimensional (2D) trilateration calculation. The method further includes evaluating a confidence metric value, determining a position of the user device based on the confidence metric value, and generating an unlock signal that unlocks a vehicle door.

A method for localizing a user device using a Time of Flight (ToF) antenna array disposed on a vehicle, the method includes determining, via a ToF localization controller, that the user device is less than a threshold distance from the vehicle, determining an angle of arrival via the ToF localization controller and the ToF antenna array, and generating an unlock signal that unlocks a vehicle door responsive to determining that the user device is less than the threshold distance from the vehicle door.

A casing has a housing section adapted to house an electronic key. The casing is formed of a material capable of blocking a particular frequency band. A controller is configured to cause an actuator to actuate a movable portion of the electronic key to transmit a signal for controlling a controlled device with the particular frequency band while switching a part of the casing into a state that the signal is allowed to pass, in a case where a transceiver receives a trigger signal from a mobile device.

A remote key is provided with an electronic wiring arrangement for generating and processing signals. The remote key includes a first antenna for transmitting and/or receiving the signals, and a wiring carrier on which the antenna is formed as a track. The remote key also includes a housing in which the wiring carrier, the first antenna and the electronic wiring arrangement are arranged. The housing comprises a second antenna.

A long range low frequency antenna having an elongated magnetic core; a coil surrounding the elongated magnetic core; a bobbin; where the elongated magnetic core is introduced in a cavity of the bobbin; and a housing overmolded on the bobbin in a waterproof manner. The antenna also comprises at least one damper located at one extreme of the elongated magnetic core. The at least one damper is made of an elastic and thermally-stable compound having a resin and a first filler including a natural mineral filler. Therefore, longitudinal dilatations, shrinkage, mechanical shocks, and vibrations of the elongated magnetic core are absorbed by the at least one damper, avoiding an impact over an inductance variation of the coil.

A radio frequency (RF) circuit is provided and includes an antenna, a printed circuit board and a RF chip. The printed circuit board includes a stack of layers. The stack of layers includes a grounded layer. The grounded layer includes a slit, a dielectric area, a first grounded area and a second grounded area. The dielectric area includes dielectric material and is disposed between the first grounded area and the second grounded area.
