ANTENNA AND ELECTRONIC DEVICE INCLUDING THE SAME

In an embodiment, an electronic device may include a housing having an inner space, a first printed circuit board including a wireless communication circuit, an antenna structure connected to the wireless communication circuit through a first electrical path, and a tunable circuit having a first resistance value and disposed on a second electrical path. The electronic device may further include a low-resistance circuit disposed on a third electrical path branched from the second electrical path, and including a resistor and an inductor, the resistor having a second resistance value determined based on the first resistance value, and the inductor having a constant inductance value and disposed between the resistor and the ground. The electronic device may also include at least one processor configured to control the tunable circuit.
