Metal frame transmitting electromagnetic waves or having function of heat radiation

Abstract

The invention provides a metal frame transmitting electromagnetic waves or having a function of heat radiation, wherein the metal frame includes metal as its main substance, wherein the metal frame isapplied to a device having a function of transmitting electromagnetic waves, and wherein the metal frame includes a slit formed on at least a partial area of the metal frame so as to allow electromagnetic waves to be transmitted and to make the normal operation of the above device possible, wherein the slit forming area is larger than an area occupied by a wireless transmitting / receiving module for transmitting electromagnetic waves, and wherein an entire area occupied by the wireless transmitting / receiving module is located under at least part of the slit forming area. The characteristic oftransmitting electromagnetic waves is provided to the metal frame. Accordingly, the metal frame may be applied and used as an outer case of a device being provided with transmitting / receiving modulesfor wireless communication or wireless charging, and the metal frame may also be used as an interior material of the device.

Description

technical field [0001] The present invention relates to a metal frame capable of transmitting radio waves or having heat dissipation properties, more particularly, to the above-mentioned metal frame capable of transmitting radio waves or having heat dissipation properties, and at least a part of the metal frame is formed with a stipulation capable of transmitting radio waves. The wide slit can be used as a casing or a built-in device with at least one related wireless sending / receiving module among near field communication (NFC), wireless power transfer (wireless power transfer) and mobile payment device. However, since the generation of eddy currents (eddy currents) interferes with the transmission of radio waves, it is very important to establish conditions that do not generate eddy currents. For this reason, the area where the slit is formed needs to be larger than the size of the module (area occupied by the module). Background technique [0002] In recent years, wirele...

Problems solved by technology

[0007] In other words, until now, mobile devices with plastic material appearance have been mainly produced with the aim of reducing weight, but there is a limit to obtaining high texture through plastic, so it is necessary to find an alternative material that can express a different texture, but actually not easy

[0008] The appearance of metal can be regarded as the best candidate among candidates to replace the appearance of plastic, but metal has shielding ability against electric waves and is actually used as an excellent shielding material, so it is not suitable for use in wireless charging, near Various wireless transmission / reception modules such as distance wireless communication (NFC) and Samsung Pay
