1. An electronic device comprising:
- a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite the first direction, and a side member surrounding at least a portion of a space between the first surface and the second surface;
an inner structure positioned between the first surface and the second surface;
a conductive coil positioned inside the housing, the conductive coil having an axis substantially perpendicular to the first direction or the second direction, and being wound around a portion of the inner structure;
a communication circuit positioned inside the housing, the communication circuit being configured to cause the conductive coil to generate a magnetic flux;
a display exposed through at least a portion of the first surface; and
a processor positioned inside the housing, the processor being electrically connected to the communication circuit and the display,wherein the second surface comprises a first portion which is formed of a conductive material and includes two openings separated from each other, a second portion which is formed of a non-conductive material and fills one of the two openings, and a third portion which is formed of a non-conductive material and fills another of the two openings;
wherein the conductive coil is positioned generally under the first portion when viewed from above the second surface; and
wherein the inner structure extends between the two openings when viewed from above the second surface, and enables the generated magnetic flux to penetrate through the two openings.
