摘要

Provided are a back cover for a portable terminal and a back cover-integrated antenna module including the same. A back cover for a portable terminal according to an embodiment of the present invention is disposed on the back surface of a portable terminal body, and includes a pattern portion, which is formed to pass through the back cover formed of a metal material at a region corresponding to at least one antenna and configured to reduce generation of an eddy current.

Each of the antennas 121, 122, and 123 may include a circular, elliptical, or quadrangular plate-shaped coil which is wound in a clockwise direction or a counterclockwise direction, but may not be limited thereto, and may be formed by patterning a conductor such as a copper film, or the like on at least one surface of a circuit board 124 formed of a synthetic resin such as polyimide (PI), PET, or the like, and may be formed in a loop-shaped metal pattern using conductive ink.

Hereinafter, the antennas 121, 122, and 123 are described to be formed in the loop-shaped pattern on at least one surface of the circuit board 124 for convenience of the description.

In this case, the antenna 121, 122, and 123 may be single type including any one of a WPT antenna 121 for wireless power transmission, an MST antenna 122 for magnetic, security payment, and an NFC antenna 123 for wireless communication or may be a combo type including at least two antennas of the WPT antenna 121, the MST antenna 122, and the NFC antenna 123.

For example, both of the MST antenna 122 and the NFC antenna 123 may be disposed at the outside of the WPT antenna 121 in the antennas 121, 122, and 123 (see FIG. 1).

Here, the WPT antenna 121 may serve as a reception coil configured to receive a power signal supplied from the wireless power transmission module, may operate in an induction coupling method on the basis of an electromagnetic induction phenomenon using a frequency band from 100 kHz to 350 kHz, and may operate in a magnetic resonance method using a resonance frequency of 6.78 MHz frequency band.
