Abstract
Disclosed is an antenna module for wireless power transmission and reception, wherein a loop-shaped coil for wireless power transmission and reception is formed using two wires having different diameters, so that a reduction in charging efficiency is prevented. The disclosed antenna module for wireless power transmission and reception may comprise: a first coil which is wound around a first winding shaft to form a first loop and has a first coil diameter; a second coil which is wound around the outer periphery of the first coil to form a second loop and has a second coil diameter thicker than the first oil diameter; a base substrate disposed to overlap portions of the first coil and the second coil; and a coil connection pattern formed on one surface of the base substrate and connected to the first coil and the second coil.
