Abstract: A method of extracting an Integrated Circuit (IC) current is provided. The method includes generating a transfer function value by using a voltage measured in a node nearest an input terminal of the IC, substituting the generated transfer function value for a reverse fast Fourier transform function, so as to extract the IC voltage, and extracting the IC current from the extracted IC voltage through a simulation in a time domain.

Abstract: Various embodiments of the present disclosure provide an antenna device and/or an electronic device including the antenna device. The antenna device may include: a circuit board; a conductive layer disposed in a partial region of the circuit board; a first radiation conductor disposed at one side of the conductive layer on the circuit board; and second radiation conductors disposed at one side of the conductive layer on the circuit board, the second radiation conductors being respectively disposed at opposite sides of the first radiation conductor to be symmetrical to each other. The first radiation conductor may transmit or receive a wireless signal in a first frequency band, and the second radiation conductors may transmit or receive a wireless signal in a second frequency band that is different from the first frequency band.
