Disclosed is a combo antenna module in which an accommodation groove is formed in a coil pattern and a connection pattern connected to a coil pattern disposed on another surface is disposed in the accommodation groove so as to minimize a mounting space and provide antenna performance greater than or equal to that of a conventional antenna module. The disclosed combo antenna module comprises a coil pattern for short-range communication and a coil pattern for wireless power transmission. The coil pattern for wireless power transmission has the accommodation groove formed by varying the line width of the coil pattern disposed on one surface, and the connection pattern for connecting the coil patterns disposed on the other surface is disposed in the accommodation groove so as to minimize a mounting space and provide antenna performance greater than or equal to that of a conventional antenna module.

Provided herein is a magnetic sheet. The magnetic sheet according to one embodiment of the present invention includes a magnetic layer formed of crushed pieces of a magnetic body to improve flexibility of the magnetic sheet, and a thin film coating layer formed on at least one surface of the magnetic layer to maintain the magnetic layer in a sheet shape and buffer an external force applied to the crushed pieces of the magnetic body. According to the present invention, since the magnetic sheet is improved in mechanical strength properties, such as a tensile property, a bending property, and the like, to have significantly superior flexibility, degradation of physical properties, such as magnetic permeability and the like, caused by physical damage such as unintended cracks in the magnetic body provided in the magnetic sheet can be prevented even in the process of storing, transferring, and attaching the magnetic sheet to a target object and during usage of an electronic device provided with the target object to which the magnetic sheet is attached, and the magnetic sheet can be attached to a target surface of the target object with a superior adhering force even when a stepped portion is present at the surface, and at the same time, the magnetic sheet can block the influence of a magnetic field on parts of a portable terminal device or a human body of a user using the portable terminal device, significantly increase transmission and reception efficiencies and distances of a data and/or wireless power signal, and maintain the above-described performance for a long period of time, such that the magnetic sheet can be widely used in various portable devices such as mobile devices, smart appliances, devices for the Internet of Things, and the like.
