1. An electronic device comprising:
a housing comprising a first plate that is directed outward in a first direction, a second plate that is directed outward in a second direction opposite to the first direction, and a side member that surrounds a space between the first and second plates;
a first antenna structure located in the space, wherein the first antenna structure comprises:
a first conductive structure comprising a first conductive layer, which is substantially parallel to the second plate and includes a first edge extending in a third direction perpendicular to the first direction and a first notch portion disposed at the first edge, and
a first conductive wall, which is substantially perpendicular to the first conductive layer and includes a second notch portion extending from the first edge and connected to the first notch portion;
a second conductive structure located in the first notch portion and electrically isolated from the first conductive structure;
a third conductive structure located between the first conductive layer and the first plate and electrically isolated from the first conductive structure and the second conductive structure, wherein the third conductive structure comprises:
a second conductive layer facing the first conductive layer and having a quadrilateral shape, the second conductive layer comprising a second edge extending parallel to the first edge, a third edge extending perpendicular to the second edge, a fourth edge extending parallel to the third edge, and a fifth edge extending parallel to the second edge, wherein a distance to the fifth edge from the first conductive wall is shorter than a distance to the second edge from the first conductive wall,
a second conductive wall facing the first conductive wall and extending from the second edge,
a third conductive wall connected to the third edge and the second conductive wall and perpendicular to the second conductive layer and the second conductive wall, and
a fourth conductive wall connected to the fourth edge and the second conductive wall and perpendicular to the second conductive layer and the second conductive wall; and
a wireless communication circuit electrically connected to the second conductive structure and configured to transmit or receive a signal having a frequency of 3 GHz to 100 GHz.
