20150288055
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Apr. 4, 2014 in the Korean Intellectual Property Office and assigned Serial number 10-2014-0040492, and of a Korean patent application filed on Apr. 7, 2014 in the Korean Intellectual Property Office and assigned Serial number 10-2014-0041476, the entire disclosure of each of which is hereby incorporated by reference.
The present disclosure relates to protection and characteristic improvement of elements of antennas.
Recently, wireless communication technology has been developed for easily transferring and sharing various types of data such as sounds, images and pictures. With this development of wireless communication technology, the diversification of information and the speed of communication have also been improved.
Furthermore, in order to keep up with the recent trend of digital convergence, electronic devices such as smartphones and tablets have been developed to provide various functions. For example, services based on functions of communication technologies such as digital multimedia broadcasting, (DMB), global positioning system (GPS), Bluetooth (BT), radio frequency identification (RFID) and Wi-Fi may be provided. To provide such services, an electronic device may be provided with one or more antennas.
The thicknesses of electronic devices such as smartphones or tablets have been decreased, but the number of components of such devices has been increased to support various functions. A thin and complicated electronic device may give satisfaction and provide various functions to a user, but may deteriorate in terms of a radio wave transmitting/receiving environment.
For example, according to the related art, an antenna pattern may be disposed in an injection-molded article. However, the antenna pattern may be deformed due to a high-temperature and high-pressure environment of an electronic device manufacturing process or an external impact or external pressure that may occur while an electronic device is used by a user. Furthermore, a radiation characteristic of an antenna may be changed due to other electronic elements arranged around the antenna, and thus it may be necessary to change the antenna pattern. However, according to the related art, it is almost impossible to change the antenna pattern since the antenna is sealed after being disposed.
The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

Referring to
The case 100 may be made of a material that enables an antenna pattern to be disposed in a designated manner. For example, the material of the case 100 may enable antenna disposition through LDS or antenna disposition through printing (e.g., dot printing, inkjet printing, or pad (e.g., a silicon pad) printing), double injection, Flexible printed circuit board (FPCB) structure, steel use stainless (SUS) structure, or metal ink painting.
According to an embodiment of the present disclosure, the case 100 that supports the LDS may be made of platable plastic obtained by mixing a nonmetallic material (e.g., plastic) with at least one metallic material (e.g., palladium) so as to allow antenna pattern plating or printing. According to various embodiments of the present disclosure, the case 100 may be a carrier in which the antenna 200 is disposed. The case 100 may be a frame in which a display or a battery of the electronic device is placed. Alternatively, the case 100 may be a substrate on which a printed circuit board is placed.
According to various embodiments of the present disclosure, the case 100 may be a part or the entirety of at least one of a front part 130, a rear part 110, or a side part 120 of the electronic device. Here, the front part 130, the rear part 110, and the side part 120 may be referred to thus on the assumption that an image output direction of a display is a front direction. Accordingly, the front part 130, the rear part 110, and the side part 120 may be changed according to a form of arrangement in the electronic device or observation thereon. According to an embodiment of the present disclosure, the case 100 may include a part of a corner area of the rear part 110 and a part of a corner area of the side part 120. Alternatively, the case 100 may include the side part 120 that includes a border (e.g., a rectangular border) of the electronic device and a part of a rear area disposed on the corner area of the side part 120. An antenna protection part 160 may be disposed on at least a part of the case 100.
The antenna protection part 160 may include at least one projection surrounding an area on which the antenna 200 is disposed or at least one rail extending from the projections. According to various embodiments of the present disclosure, the antenna protection part 160 may be raised from a surface of the case 100 by a certain distance. The antenna protection part 160 raised in the form of a rail may be provided in the form of a sidewall that protrudes from the surface of the case 100 by a certain distance. An upper end part of the sidewall may be rounded. According to various embodiments of the present disclosure, the antenna protection part 160 may be lowered from the surface of the case 100 by a certain distance. Alternatively, at least a part of the antenna protection part 160 may be raised (or may protrude or may be embossed) at an adjacent area to the area on which the antenna 200 is disposed and the other part of the antenna protection part 160 may be lowered (or engraved).
According to various embodiments of the present disclosure, the antenna protection part 160 may be formed through injection molding according to a mold pattern while the case 100 is manufactured. According to various embodiments of the present disclosure, when the injection molding is completed, the antenna protection part 160 may be additionally disposed (e.g., mounted or printed) on the surface of the case 100. The antenna protection part 160 may be made of the same material as that of or a different material from that of the case 100.

Alternatively, the antenna protection unit 160 may be made of the material of the case 100 which allows the application of the LDS. Alternatively, the antenna protection unit 160 may be a metal line disposed in the form of a rail at an adjacent area to the antenna 200 disposed on the case 100.
According to various embodiments of the present disclosure, the raised-type antenna protection part 160 may reduce an external pressure applied to the antenna 200, while an injection material covers the antenna 200 during a second injection molding process after the antenna 200 is disposed. For example, the case 100 printed or plated may be disposed in an additional mold chamber, and then may be injection-deformed in relation to manufacturing of the case 300.
An injection fluid introduced into the mold chamber may be disposed in the form of a mold while flowing on the surface of the case 100 in a high-temperature and high-pressure state. In this process, a speed and pressure of the injection fluid that flows on a surface of the antenna 200 may be decreased by the raised antenna protection part 160 disposed at the periphery of the antenna 200. Accordingly, the antenna protection part 160 may prevent or reduce damage to the antenna 200 caused by an injection molding process. Regarding the lowered-type antenna protection part 160, the injection fluid firstly fills the lowered antenna protection part 160 and flows on the surface of the antenna 200, so that the pressure applied to the antenna 200 may be reduced. In various embodiments below, it is assumed that the antenna protection part 160 is raised at an adjacent area to the antenna 200.

For example, a manufacturing process of the antenna 200 may include a patterning process for forming a plating pattern (or a printing pattern) by laser-processing, based on a designated pattern, the surface of the case 100 to which the LDS is applied, and an arrangement process for forming the antenna 200 (or an antenna pattern or an antenna radiator) by plating with (or printing or depositing) a conductive material (e.g., a metallic material) on a pattern. A depth of the pattern of the patterning process may correspond to a thickness of the antenna 200 plated. The pattern having a certain depth may be plated with the antenna 200 so that the thickness of the antenna 200 may be equal or similar to the depth of the pattern. According to various embodiments of the present disclosure, the antenna 200 may include a contact connection part 210, a pattern part 220, and an end part 230.
