Disclosed herein is a frame including a metal layer and being capable of transmitting electric waves that may be applied to a device including a wireless charging module or a wireless communication module, and wherein each of the modules may be selected from at least one of a charging transmitter, a charging receiver, and a near field communication module. Herein, for example, a mobile device including at least one wireless charging receiver and being capable of performing wireless charging accordingly, may be expected to perform the wireless charging more easily despite having its external feature configured of a metallic material having a more excellent and luxurious texture and having a more enhanced durability.

The present invention relates to an antenna radiator having heterogeneous antennas cross-linked with each other, and a manufacturing method therefor. More specifically, the present invention provides an antenna radiator having heterogeneous antennas cross-linked with each other, wherein the antenna radiator has an antenna pattern constituted with an in-mold antenna provided on an end of a frame, and a printed or plated antenna provided on an adjacent area to the in-mold antenna, the in-mold antenna having a protrusion on at least one area thereof, and the printed or plated antenna provided to overlap the protrusion such that the in-mold antenna and the printed or plated antenna are cross-linked with each other; and a manufacturing method for the antenna radiator.

Disclosed herein is a metal frame for a device being equipped with a wireless charging transmitter or receiver including a plurality of perforation holes configured in at least one partial area of the metal frame, wherein the perforation hole has a diameter ranging from sub nm to several &#x3bc;m, and wherein an average distance between an arbitrary point A on a circumferential surface of a perforation hole, among the plurality of perforation holes, and an arbitrary point B on a circumferential surface of another perforation hole being adjacent to the perforation hole is equal to or less than a skin depth corresponding to a metallic material of the metal frame, and wherein point A and point B respectively correspond to points indicating a longest distance between the circumferential surfaces of each perforation hole to which point A and point B belong. Accordingly, the metal frame is expected to perform wireless charging by including at least a wireless charging receiver, i.e., enabling wireless charging to be carried out smoothly despite equipping a mobile device with a metal frame for its outer feature instead of a plastic frame, wherein the metal frame provides an excellent texture of premium quality and outstanding durability as compared to the plastic frame.
