Provided is a wireless ear module having a UWB antenna to easily obtain location information of a wireless ear module case and ear modules. The wireless ear module comprises: ear modules for receiving and playing a sound source signal from an electronic device; and a case comprising an upper housing and a lower housing which are rotatably coupled, and for storing the ear modules. The ear modules and/or the case transmit a location positioning signal, and the location positioning signal is a signal for sensing the distance and direction from the electronic device to the ear modules or the case.

Wireless earphones

Proposed is an antenna module in which a partial area, which overlaps with a magnet mounted on an antenna sheet, of the entire area of a shielding sheet is punched out to prevent the shielding sheet from being magnetically saturated (magnetized) by the magnet. The proposed antenna module comprises: the antenna sheet having a radiation pattern formed thereon and having a magnet array formed along the outer circumference of the radiation pattern inserted thereto; and the shielding sheet laminated on the antenna sheet, and having an anti-overlapping hole formed in the area overlapping with the magnet array.

Antenna module

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.
