Proposed is a combo antenna module which laminates a loop coil and an antenna sheet to configure a combo antenna, thereby preventing the degree of design freedom from being lowered and minimizing the manufacturing cost. The proposed combo antenna module includes a magnetic sheet, a loop coil disposed on the upper surface of the magnetic sheet, and an antenna sheet having the area smaller than that of the magnetic sheet, and disposed on the upper surface of the magnetic sheet, in which the antenna sheet overlaps a part of the loop coil.

Combo antenna module

Provided is an antenna module for increasing a recognition area by using a metal deco or a deco panel of a portable terminal as an auxiliary radiator of a radiation pattern for near field communication. The provided antenna module includes: a metal deco disposed on a rear side of a portable terminal; and a radiation pattern connected to the metal deco, in which the metal deco is spaced at both ends by means of a slit, and one end is configured to be directly connected with one end of a radiation pattern so as to act as an auxiliary radiator of the radiation pattern.

Antenna module

Provided is an antenna module in which magnetic sheets are disposed on one surface and the other surface of an antenna sheet having a plurality of radiation patterns formed thereon, and an overlapping area between the magnetic sheets is formed to maximize antenna performance for electronic payment, short-range communication, and wireless charging. The provided antenna module comprises: the antenna sheet having radiation patterns formed thereon; a first magnetic sheet disposed on one side of the antenna sheet; and a second magnetic sheet disposed on the other side of the antenna sheet, wherein the first magnetic sheet and the second magnetic sheet form an overlapping area.

Provided are a combination antenna module and a portable electronic device including the same. There is provided a combo antenna module that includes an antenna unit including and a switching unit. The antenna unit includes a circuit board, a first wireless power transmission antenna, and a second wireless power transmission antenna of which manner is different from that of the first wireless power transmission antenna. The switching unit includes a first capacitor and a second capacitor connected in parallel to the second wireless power transmission antenna, and a switch, disposed between the first capacitor and the second capacitor, to be opened or closed based on an operation mode of the antenna unit. The second antenna and the second capacitor form a closed loop which is coupled with the first antenna when the switch is opened.

Combination antenna module and portable electronic device including same

Provided are a combination antenna module and a portable electronic device including same. There is provided a combo antenna module that includes an antenna unit and a switching unit. The antenna unit includes a circuit board, a first wireless power transmission antenna, and a second wireless power transmission antenna of which manner is different from that of the first wireless power transmission antenna. The switching unit is configured to be connected or disconnected the first antenna and the second antenna based on an operation mode of the antenna unit.

Provided are an antenna unit and a wireless power transmission module. There is provided an antenna unit that includes a circuit board, and a first antenna pattern formed on a surface of the circuit board for wireless power transmission and formed of a single conductor including a plurality of windings. The single conductor has a different line width depending on position. There is provided a wireless power transmission module that includes any one of the antenna units, and a shielding unit disposed on one surface of the antenna unit and configured to shield a magnetic field.

Antenna unit and wireless power transmission module including same

Provided are a shielding unit for wireless charging and a wireless power transfer module including the same. The shielding unit for wireless charging includes a first sheet for a wireless power transfer antenna, and a second sheet for another antenna operating in a different frequency band from that of the wireless power transfer antenna.
