Claim 6:
7. An electronic device comprising:
a housing comprising a first plate and a second plate; and
a first antenna structure,
wherein the first antenna structure comprises a board disposed between the first plate and the second plate, wherein the board comprises:
a first surface facing the first plate,
a second surface facing the second plate,
a plurality of insulating layers stacked on top of each other between the first surface and the second surface,
a first conductive layer disposed on the first surface,
a second conductive layer disposed on the second surface,
a plurality of strips disposed between the plurality of insulating layers, and
a plurality of vias connecting at least one or more of the first conductive layer, the second conductive layer, or the plurality of strips to each other and disposed in the plurality of insulating layers;

a first conductive structure, a second conductive structure, a third conductive structure, and a fourth conductive structure formed as part of the plurality of strips and the plurality of vias; and
a wireless communication circuit electrically connected to at least one of the vias and configured to transmit or receive at least one signal having a frequency of 3 GHz to 100 GHz,
wherein the first edge of the first conductive layer comprises a first notch portion, the first conductive structure is perpendicular to the first conductive layer and extends from one edge at which the first notch is disposed, the second conductive structure is disposed to be spaced apart from the first notch portion and is electrically connected to the wireless communication circuit, the third conductive structure is spaced apart from the first notch portion and coupled with the first conductive layer so as to define a first cavity, and the fourth conductive structure is surrounded by the third conductive structure and is coupled with the first conductive layer so as to define a second cavity.
