Electronic device including antenna

An electronic device comprising:

• an antenna array comprising a plurality of antenna elements;
• a wireless communication circuit configured to perform communication with a signal source outside of the electronic device through the antenna array in an ultra-wideband (UWB);
• and
• a processor electrically connected to the wireless communication circuit,
• wherein the wireless communication circuit is configured to simultaneously radiate a first circularly polarized wave and a first linearly polarized wave through a first antenna element among the plurality of antenna and a second linearly polarized wave through a second antenna element among the plurality of antenna elements,
• wherein the first circularly polarized is included in a first frequency band of the UWB,
• wherein the first linearly polarized wave and the second linearly polarized wave is included in a second frequency band of the UWB at least partially different from or wider than first frequency band,
• wherein the first linearly polarized wave has more dominant electric field in the second frequency band than the first circularly polarized wave,
• wherein the first linearly polarized wave and the second linearly polarized wave have a same polarization direction in which an electric field oscillates, and
• wherein the processor is configured to perform a positioning function with respect to the signal source using the first linearly polarized wave and the second linearly polarized wave in the second frequency band.
