1. An electronic device, comprising:
a housing;
a first communication circuit;
a second communication circuit different from the first communication circuit;
a plurality of first antennas including patch antennas electrically connected the first communication circuit; and
a second antenna including a metal antenna formed in at least a portion of the housing, the second antenna electrically connected to the first communication circuit and the second communication circuit,
wherein the first communication circuit is configured to:
transmit a first positioning signal using the second antenna or one of the plurality of first antennas;
receive a first reception signal using at least one of the plurality of first antennas, the first reception signal transmitted from a positioning target in response to the first positioning signal;
transmit a second positioning signal using the second antenna or one of the plurality of first antennas, when an intensity of the first reception signal is less than a threshold;
receive a second reception signal using at least one of the plurality of first antennas, the second reception signal transmitted from the positioning target in response to the second positioning signal;
receive a third reception signal using the second antenna, the third reception signal transmitted from the positioning target in response to the second positioning signal; and
determine a distance and an angle of arrival of the positioning target based on the second reception signal and the third reception signal.
