1. An electronic device comprising:
a display panel including an antenna, the antenna comprises:
a first antenna portion;
a second antenna portion spaced apart from the first antenna portion in a first direction; and
a plurality of intermediate antenna portions disposed between the first antenna portion and the second antenna portion and electrically connected to the first antenna portion and the second antenna portion,
wherein the first antenna portion comprises a first pattern portion and a first line portion having a first width in a second direction crossing the first direction, and the second antenna portion comprises a second pattern portion and a second line portion having a second width in the second direction that is larger than the first width,
wherein the first antenna portion is matched at a first impedance equal to intrinsic impedance of free space,
wherein the first antenna portion is configured to radiate a first signal having a first frequency only through traveling wave resonance, and
the plurality of intermediate antenna portions is configured to radiate at least one second signal having a different frequency than the first signal through the traveling wave resonance and a standing wave resonance.
