Disclosed is an electronic device, which includes a plurality of driving coils that are sequentially arranged in a first direction in a plan view, a plurality of sensing electrodes that are spaced and insulated from the plurality of driving coils and are sequentially arranged in a second direction orthogonal or pseudo-orthogonal to the first direction in a plan view, and a processor that is electrically connected with the plurality of driving coils and the plurality of sensing electrodes. At least one of the plurality of sensing electrodes is electrically coupled with a stylus excited by a magnetic field generated by the plurality of driving coils. The processor applies a driving signal to the plurality of driving coils, receives a response signal to the driving signal from the plurality of sensing electrodes, and identifies a contact location of the stylus based on the response signal.
