Radio frequency device and electronic device having the same

An electronic device comprising:

• a display panel including an active area and a peripheral area adjacent to the active area;
• and
• an antenna disposed on the active area and configured to transmit, receive, or transmit and receive a signal having a frequency band, wherein:
• the antenna comprises a plurality of antenna portions arranged in a first direction,
• one of the plurality of antenna portions is matched at an impedance equal to intrinsic impedance of free space, and
• the signal is radiated through a traveling wave resonance and a standing wave resonance.

A radio frequency device comprising:

• a base layer;
• a first antenna portion disposed on the base layer;
• a second antenna portion disposed on the base layer and spaced apart from the first antenna portion in a first direction;
• and
• a plurality of intermediate antenna portions disposed on the base layer and positioned between the first antenna portion and the second antenna portion when viewed in a plane, the plurality of intermediate antenna portions is 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.

An electronic device comprising:

• a display panel including an antenna, the antenna comprises:
• a first antenna portion disposed on a first end of the antenna and including a first pattern portion and a first line portion, wherein the first antenna portion is matched at a first impedance equal to intrinsic impedance of free space;
• a second antenna portion disposed on a second end of the antenna, the second antenna portion including a second pattern portion and a second line portion, the second antenna portion is 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, each of the plurality of intermediate antenna portions includes an intermediate pattern portion and an intermediate line portion,
• 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.
