1. An antenna module for wireless power transmission and reception comprising:
a first coil wound around a first winding shaft to form a first loop, and having a first coil diameter;
a second coil wound around an outer circumference of the first coil to form a second loop, and having a second coil diameter greater than the first coil diameter;
a base substrate disposed to overlap at least parts of the first coil and the second coil; and
a coil connection pattern formed on one surface of the base substrate, and connecting the first coil and the second coil,
wherein the coil connection pattern is soldered with a second end of the first coil and a first end of the second coil, and
wherein the first coil and the second coil are connected by the coil connection pattern, and form a loop-shaped coil for wireless power transmission and reception.
