Abstract
According to an example, adult verification of the aerosol generating device is performed through Bluetooth low energy (BLE) communication using a Planar Inverted-F Antenna (PIFA) including a circuit board, a power supply line, an antenna pattern, and a ground line.
Claims10
A method of authenticating a user performed by an aerosol generating device, the method comprising:
- transmitting a beacon for establishing a wireless communication channel using Bluetooth Low Energy (BLE) communication;
- establishing the wireless communication channel with a user terminal based on the beacon;
- receiving adult verification data for a user of the aerosol generating device from the user terminal through the wireless communication channel;
- and
- authenticating the user of the aerosol generating device based on the adult verification data.
2 more elements
A planar inverted-F antenna (PIFA) of an aerosol generating device for transmitting and receiving a wireless signal, the PIFA comprising:
- a circuit board;
- a feed line formed on an upper surface of the circuit board;
- an antenna pattern comprising one or more strip lines electrically connected to the feed line, the antenna pattern being formed on a dielectric substrate of the circuit board;
- and
- a ground line electrically connected to the antenna pattern,
- wherein a total length of the one or more strip lines is predetermined based on an arrangement relationship between the one or more strip lines and a frequency of the wireless signal.
