An electronic device includes a housing, a circuit board, a first electronic component, a first conductive plate, and a first antenna. The housing includes a support member and a side frame surrounding a periphery of the support member. The support member includes a first conductive area. The circuit board is disposed on a surface of the support member and includes a feeding point on a surface of the circuit board. The first electronic component is disposed on the surface of the support member. The first conductive plate is disposed on a surface of the first electronic component. The first conductive area is disposed between the first electronic component and the side frame. The first antenna includes a first radiator, a first feeding part, and a first signal terminal. At least a portion of the first electronic component is disposed between the first conductive area and the circuit board.
