Method for operating an antenna and a electronic device implementing the same

One embodiment of the present disclosure proposes a method for operating the electronic device, the antenna and implement them. The electronic device to operate the antenna in accordance with one embodiment of the present disclosure is directed to a power supply module that includes a first power supply terminal and the second power supply terminal; Current supply module for selecting one of the power supply terminal, and supplying a current to the selected power supply terminal; Antenna module comprising a first antenna and the second antenna; Connection module for connecting the feed module and the antenna module; And it may include a control module for controlling the current supply module. Wherein the connection module, including a plurality of wirings, and a plurality of the wiring are, the said current, the length and the current in the first path flows to the first antenna from the first power supply terminal is at the second power supply terminal the length of the second path flowing through the first antenna, and arranged so that, equal to each other within a predetermined error range, the current length and the current of the third path flowing from the first power supply terminal to the second antenna is the and in the second power supply terminal it is arranged so that the fourth length are different from each other in the flowing path to the second antenna. Further, it is possible that other embodiments.
