1. An electronic device comprising:
a housing having a front surface and a rear surface;
a first antenna disposed in a loop form inside the housing;
a second antenna disposed in an area surrounded by a radiator of the first antenna when viewed from above the rear surface;
a printed circuit board comprising wireless communication circuitry for operating the first antenna and the second antenna, and electrically connected to the first antenna and the second antenna;
an electromagnetic interference (EMI) shielding sheet; and
a heat dissipation sheet disposed under the first antenna and the second antenna,
wherein at least one through-hole is formed penetrating the EMI shielding sheet and the heat dissipation sheet to allow the electrical connection between the first antenna and the printed circuit board and the electrical connection between the second antenna and the printed circuit board,
wherein the first antenna is positioned between the rear surface and the EMI shielding sheet.
