Presented is an antenna module for wireless power transmission and reception in which an inner loop pattern is disposed in the inner peripheral area of an outer loop coil so as to provide a constant charging recognition rate regardless of location. The presented antenna module for wireless power transmission and reception comprises: a base substrate; a first antenna which is disposed on the upper surface of the base substrate and includes a first radiation pattern forming a first loop; and a second antenna which is stacked on the upper surface of the base substrate and includes a coil wound along the outer periphery of the first loop to form a second loop.

A wireless charging transmit end is provided in this application, which includes a dual-polarized antenna which includes at least one dual-polarized element and a signal processing apparatus. Each dual-polarized element includes a first linearly polarized element and a second linearly polarized element that are mutually orthogonal and respectively receive a first wireless signal and a second wireless signal from the receive end. The signal processing apparatus obtains a first energy signal and a second energy signal based on a waveform relationship between the first wireless signal and the second wireless signal. The first energy signal is sent to the receive end by the first linearly polarized element, and the second energy signal is sent to the receive end by the second linearly polarized element. The first energy signal and the second energy signal are combined into an energy signal matching the receive end.

A power reception device includes: a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface surrounding a space between the first surface and the second surface; a coil antenna wound in a circle; a shielding sheet disposed over the coil antenna; and a first magnet and a second magnet adjacent to an outermost coil of the coil antenna and disposed to be spaced apart from the outermost coil. The first magnet is disposed so that a portion of magnetism induced by the first magnet is formed in the first direction. The second magnet is disposed so that a portion of the magnetism induced by the second magnet is formed in a third direction that is an outside direction from a center of the coil antenna.
