Abstract
An example electronic device includes a first antenna; a second antenna; a driver integrated circuit (IC) configured to transmit magnetic field signal through at least one of the first antenna and the second antenna; a switch configured to switch between short-circuiting connection between the driver IC and the first antenna and opening connection between the driver IC and the first antenna; and a filter configured to filter a pre-determined frequency and connected to the first antenna, the second antenna and the driver IC. The driver IC is configured to transmit the magnetic field signal using both the first antenna and the second antenna based on the switch short-circuiting the connection between the driver IC and the first antenna.
