     2. Description of the Related Art 
     Recently, as mobile wireless terminals that separately use various kinds of bandwidths, such as CDMA, PDA, DCS, and GSM, or use all of the bandwidths, have come into widespread use, terminals with various functions and designs have appeared. As the terminals have gradually been reduced in size, thickness, and weight, the diversity of the functions of the terminals has attracted attention. Therefore, emphasis is placed on reducing the volume of the terminals while the terminals maintain the function of an antenna. 
     Particularly, in a case of an antenna, for example, a rod antenna or a helical antenna that protrudes from the outside of a terminal by a predetermined length has excellent characteristics because of omnidirectional radiation. However, the rod antenna or the helical antenna of the terminal is most susceptible to damage when it falls down, and reduces portability. Therefore, research has been conducted on an in-molding antenna that is formed integrally with a case of a mobile communication terminal.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 
       FIG. 1  is a cross-sectional view illustrating a mobile communication terminal case according to an exemplary embodiment of the invention. 
     Referring to  FIG. 1 , a mobile communication terminal case  100  according to an exemplary embodiment of the invention may include a case body  110 , a conductive pattern  120 , a carrier film  130 , and conductive epoxy  140 . 
     The case body  110  may be coupled with another case body  115  to form a case of a mobile communication terminal. A printed circuit board  190  onto which various elements are mounted may be disposed inside the case of the mobile communication terminal. 
     The case body  110  may have a first surface and a second surface that face each other. The first surface may be an outer surface of the case of the mobile communication terminal, and the second surface may be an inner surface of the case of the mobile communication terminal. 
     The case body  110  of the case of the mobile communication terminal may be formed by using an in-molding process. That is, the carrier film  130  on which the conductive pattern  120  is formed is inserted into a mold used for manufacturing the case, and synthetic resin used to form the case is injected into the mold, thereby manufacturing the case. In this embodiment, when the carrier film  130  may be formed on the surface of the case body  110 , the carrier film  130  is formed integrally with the case body  110 . 
     In this embodiment, the carrier film  130  may be formed on the outer surface of the case body  110 . The conductive pattern  120  may be located between the case body  110  and the carrier film  130 . 
     The case body  110  may have a variety of shapes. In this embodiment, a via hole  111  that is formed through the inner surface and the outer surface of the case body  110  may be formed. The via hole  111  is filled with a conductive material so as to serve as a path through which the conductive pattern  120  is electrically connected to the printed circuit board  190  located inside the case. 
     The conductive pattern  120  and the carrier film  130  may be formed on the outer surface of the case body  110 . 
     The conductive pattern  120  may be an antenna pattern that is formed on one surface of the carrier film  130 . The conductive pattern  120  may be formed by using various kinds of methods. First, a conductive pattern may be printed onto the carrier film  130  by using conductive ink. Alternatively, a desired pattern may be directly formed on the carrier film by sputtering or evaporation. The conductive pattern  120  may be formed of previously manufactured metal foil which is then attached to the carrier film  130 . 
     The conductive pattern  120  includes a power feeding terminal, and may additionally include a connection terminal to provide an electrical connection to an external circuit, such as a ground terminal. In this embodiment, the power feeding terminal may be a contact area where the conductive pattern  120  is in contact with the conductive epoxy  140 . 
     The carrier film  130  may be formed of a material that is appropriate to perform in-molding labeling (IML). Specifically, the carrier film  130  that has the conductive pattern  120  formed on one surface thereof is inserted into the mold for manufacturing the case of the mobile communication terminal, synthetic resin used to form the case of the mobile communication terminal is injected into the mold, and the case is molded from the synthetic resin at optimum temperature and optimum pressure. Therefore, the material that forms the carrier film  130  needs to be a material that does not undergo significant deformation under the pressure and temperature during the in-molding labeling, and at the same time, can be formed integrally with the case of the mobile communication terminal. In this embodiment, the carrier film  130  may include a thin, insulating polymer material. 
     The via hole  111  formed in the case body  110  may be filled with the conductive epoxy  140 . The via hole  111  may be a path through which the conductive pattern  120  formed on the outer surface of the case body  110  is electrically connected to the printed circuit board  190  disposed inside the case body  110 . A separate connector may be inserted into the via hole  111  to thereby connect the conductive pattern  120  and the printed circuit board  190  to each other. However, the connector may damage the conductive pattern  120  and the carrier film  130  formed on the outside of the case body  110  or spoil the appearance of the case. 
     Further, plating may be performed on the via hole  111  so that the conductive pattern  120  and the printed circuit board  190  can be electrically connected to each other. However, a stable contact between the via hole  111  and the conductive pattern  120  may be limited. 
     In this embodiment, the via hole  111  may be filled with conductive epoxy. Here, conductive epoxy in a liquefied state fills the via hole  111 , and then, the liquefied conductive epoxy may be cured. This can enhance a physical bond between the conductive epoxy  140  and the conductive pattern  120  as compared with the plated via hole  111 . That is, the cured conductive epoxy  140  and the conductive pattern  120  do not simply make a mechanical contact therebetween. However, since the cured conductive epoxy  140  serves as a kind of adhesive, the cured conductive epoxy  140  and the conductive pattern  120  can be bonded to each other. The cured conductive epoxy may have predetermined elasticity. Therefore, even when a connector  191  is used for connection to the printed circuit board  190 , the cured conductive epoxy  140  can serve as a buffer to protect the conductive pattern  120  and the carrier film  130 . 
       FIG. 2  is a cross-sectional view illustrating a mobile communication terminal case according to another exemplary embodiment of the invention. 
     Referring to  FIG. 2 , a mobile communication terminal case  200  according to this embodiment may include a case body  210 , a conductive pattern  220 , a carrier film  230 , conductive epoxy  240 , and a conductive via  250 . 
     The case body  210  may be coupled to another case body (not shown) to form a case of the mobile communication terminal. A printed circuit board (not shown) onto which various elements are mounted may be disposed in the case of the mobile communication terminal. 
     The case body  210  may have a first surface and a second surface that face each other. The first surface may be an outer surface of the case of the mobile communication terminal, and the second surface may be an inner surface of the case of the mobile communication terminal. 
     The case body  210  of the case of the mobile communication terminal may be formed by using an in-molding process. That is, the carrier film  230  on which the conductive pattern  220  is formed is inserted into a mold for manufacturing the case, and synthetic resin used to form the case is injected, thereby manufacturing the case. In this embodiment, as the carrier film  230  may be formed on the surface of the case body so that the carrier film  230  is formed integrally with the case body  210 . 
     In this embodiment, the carrier film  230  may be formed on the outer surface of the case body  210 . The conductive pattern  220  may be located between the case body  210  and the carrier film  230 . 
     The case body  210  may have various shapes. In this embodiment, a via hole  211  may be formed through the inner surface and the outer surface of the case body  210 . The conductive pattern  220  may be electrically connected to the printed circuit board disposed inside the case by filling the via hole  211  with a conductive material or inserting a conductive material therein. 
     The conductive pattern  220  and the carrier film  230  may be formed on the outer surface of the case body  210 . 
     The conductive pattern  220  may be an antenna pattern that is formed on one surface of the carrier film  230 . The conductive pattern  220  may be formed by using various kinds of methods. First, a conductive pattern may be printed on the carrier film  230  by using conductive ink. Alternatively, a desired pattern may be directly on the carrier film by sputtering or evaporation. The conductive pattern  220  may be formed of previously metal foil which is then attached to the carrier film  230 . 
     The conductive pattern  220  includes a power feeding terminal, and may additionally include a connection terminal to provide an electrical connection to an external circuit, such as a ground terminal. In this embodiment, the power feeding terminal may a contact area where the conductive pattern  120  is in contact with the conductive epoxy  240 . 
     The carrier film  230  may be formed of a material that is appropriate to perform in-molding labeling (IML). Specifically, the carrier film  230  that has the conductive pattern  220  formed on one surface thereof is inserted into the mold for manufacturing the case of the mobile communication terminal, synthetic resin used to form the case of the mobile communication terminal is injected into the mold, and the case is molded from the synthetic resin at optimum temperature and optimum pressure. Therefore, the material that forms the carrier film  230  needs to be a material that does not undergo significant deformation under the pressure and temperature during the in-molding labeling, and at the same time, can be formed integrally with the case of the mobile communication terminal. In this embodiment, the carrier film  230  may include a thin, insulating polymer material. 
     The conductive via  250  may be formed in the via hole  111  in the case body  210 . The conductive via  250  may be formed to have a length so that one end of the conductive via  250  is in contact with the conductive pattern  220  and the other end thereof is in contact with a printed circuit board disposed inside the case of the mobile communication terminal. Therefore, the conductive via  250  may have a larger thickness than the case body  210 . 
     The conductive via  250  may be formed into a cylindrical shape with an opening  251 . When a conductive via is formed in a cylindrical shape with an opening, an additional connector is not required unlike the embodiment illustrated in  FIG. 1 . That is, the conductive via may be high enough to make contact with the printed circuit board in the case body  210 . The conductive via may have a variety of shapes. The conductive via also may have one end in contact with the conductive pattern and the other end exposed to the outside of the case body. 
     The opening  251  of the conductive via  250  may be filled with the conductive epoxy  240 . The via hole may be filled with conductive epoxy in a liquefied state, and then, the conductive epoxy may be cured. The conductive via  250  and the conductive pattern  220  may make mechanical contact, but the stability of the contact may be reduced. Like this embodiment, when the opening  251  is filled with the conductive epoxy  240 , the conductive epoxy  240  is cured, and the cured conductive epoxy  240  may serve as an adhesive between the conductive via  250  and the conductive pattern  220 . When the conductive epoxy  240  fills the opening  251 , the conductive epoxy  240  may fill the opening  251  up. When the conductive via simply has one end in contact with the conductive pattern and the other end exposed to the outside of the case body, the conductive epoxy can serve as an adhesive to increase a bonding force between the conductive via and the conductive pattern. 
       FIGS. 3A through 3C  are cross-sectional views sequentially illustrating a method of manufacturing a mobile communication terminal case according to an exemplary embodiment of the invention. 
     In  FIG. 3A , the conductive pattern  320  is formed on the carrier film  330 . 
     The carrier film  330  has an antenna pattern on one surface or antenna patterns on both surfaces thereof. For the in-molding process, the carrier film  330  having the antenna pattern thereon is inserted into the mold. Therefore, the carrier film  330  needs to be formed of a material that does not undergo significant deformation under the pressure and temperature during the in-molding process, and at the same time, can be formed integrally with the case of the mobile communication terminal. Preferably, the carrier film may be formed of a thin, insulating polymer material. 
     The conductive pattern  320  may be formed by using various kinds of methods. First, a conductive pattern may be printed onto the carrier film  330  by using conductive ink. Alternatively, a desired pattern may be directly formed on the carrier film by sputtering or evaporation. The conductive pattern  320  may be formed of previously manufactured metal foil which is then attached to the carrier film  330 . 
     In this embodiment, the conductive pattern  320  is formed on one surface of the carrier film  330 . Conductive patterns may be formed on both surfaces of the carrier film  330 . Here, the conductive patterns formed on both surfaces of the carrier film are symmetrical with each other to form a balanced antenna. 
     In  FIG. 3B , the carrier film having the conductive pattern thereon is inserted into the mold for manufacturing the case of the mobile communication terminal, and a molding material is injected into the mold, thereby forming the case body of the terminal. 
     Referring to  FIG. 3B , the carrier film  330  having the conductive pattern  320  formed thereon may be inserted into the mold  360 . The mold  360  may include a first part  361 , a second part  362 , and a third part  363 . The first part  361  is in contact with the carrier film  330  and forms a lower surface of the mold. A molding material is injected into the second part  362 , which forms an upper surface of the mold. The third part  363  is connected to a storage unit containing the molding material through a nozzle. The carrier film  330  is inserted between the first part  361  and the second part  362  of the mold. The conductive pattern  320  formed on the carrier film may be disposed in direct contact with the molding material during the molding process. 
     All of the components of the mold are coupled with each other, and the molding material is injected into the mold  360  through the nozzle under a predetermined pressure. The molding material may be formed of a polymer-based material to form the terminal case. The molding material injected into the mold fills the space between the second part  362  and the first part  361  of the mold. 
     In this embodiment, the via hole  311  may be formed in a case body  310  of the mobile communication terminal. Therefore, a protrusion  362 a for forming the via hole may be formed on the second part  362  of the mold  360 . 
     A cooling process and a curing process are performed after a compressing process of the mold  360 , such that the case body  310  of the mobile communication terminal that has the conductive pattern  320  on one surface thereof and having the via hole  311  can be formed. 
     In  FIG. 3C , conductive epoxy fills the via hole  311  formed in the case body  310  of the terminal. 
     The conductive epoxy  340  may serve as an electrical path through which the conductive pattern  320  formed on the outer surface of the case body  310  of the terminal is connected to the printed circuit board disposed inside the case body  310  of the terminal. 
       FIGS. 4A through 4D  are cross-sectional views sequentially illustrating a method of manufacturing a mobile communication terminal case according to another exemplary embodiment of the invention. 
     In  FIG. 4A , a conductive pattern  420  is formed on a carrier film  430 . 
     The carrier film  430  has an antenna pattern on one surface thereof or antenna patterns on both surfaces thereof, and is inserted into a mold to perform an in-molding process. Therefore, the carrier film  430  needs to be formed of a material that does not undergo significant deformation under the pressure and temperature during the in-molding labeling, and at the same time, can be formed integrally with the case of the mobile communication terminal. Preferably, the carrier film  430  may include a thin, insulating polymer material. 
     The conductive pattern  420  may be formed by using various kinds of methods. First, the conductive pattern may be printed onto the carrier film  430  by using conductive ink. Alternatively, a desired pattern may be directly formed on the carrier film by sputtering or evaporation. The conductive pattern  420  may be formed of previously manufactured metal foil which is then attached to the carrier film  430 . 
     In this embodiment, the conductive pattern  420  is formed on one surface of the carrier film  430 . However, conductive patterns may be formed on both surfaces of the carrier film  430 . Here, the conductive patterns formed on both surfaces of the carrier film may be symmetrical with each other to form an antenna having a balanced structure. 
     In  FIG. 4B , the carrier film  430  having the conductive pattern  420  thereon is inserted into the mold for manufacturing the case of the mobile communication terminal, and a molding material is injected into the mold, thereby manufacturing the body of the terminal case. 
     Referring to  FIG. 4B , the carrier film  430  having the conductive pattern  420  formed thereon may be inserted into a mold  460 . The mold  460  may include a first part  461 , a second part  462 , and a third part  463 . The carrier film  430  is in contact with the carrier film  430  and forms a lower surface of the mold. A molding material is injected into the second part  462 , which forms an upper surface of the mold. The third part  430  is connected to a storage unit containing the molding material through a nozzle. The carrier film  430  is inserted between the first part  461  and the second part  462  of the mold. The conductive pattern  420  formed on the carrier film may be arranged in direct contact with the molding material. 
     All of the components of the mold are coupled to each other. The molding material is injected into space of the mold  460  under a predetermined pressure. The molding material may be a polymer-based material. The molding material injected into the mold fills the space between the first part  461  and the second part  462 . 
     In this embodiment, the via hole  411  may be formed in a case body  410  of the mobile communication terminal. Therefore, a protrusion  462   a  for forming the via hole may be formed on the second part  462  of the mold  460 . 
     A cooling process and a curing process are performed after a compressing process of the mold  460 , such that the case body  410  of the mobile communication terminal that has the conductive pattern  420  formed on one surface thereof and the via hole  411  formed therein can be formed. 
     In  FIG. 4C , a conductive via  450  is formed in the via hole  411  formed in the case body  410  of the case of the mobile communication terminal. 
     In this embodiment, the conductive via  450  may have a cylindrical shape with an opening  451 . The conductive via  450  may have one end connected to the conductive pattern  420  and the other end exposed to an inner surface of the case body  410 . 
     The conductive via  450  may have various shapes. The conductive via is simply a connector, is formed in the via hole  411 , and may serve as a path through which the conductive pattern  420  and the printed circuit board are connected to each other. 
     In  FIG. 4D , conductive epoxy fills the via hole  411  of the case body. The conductive epoxy  440  may be filled to make contact with the conductive via  450  and the conductive pattern  420 . 
     In this embodiment, since the conductive via  450  having a cylindrical shape is formed in the via hole  411 , the conductive epoxy may fill the opening  451  of the conductive via. 
     In this embodiment, the conductive via  450  formed in the via hole  411  may used as a main path through which the conductive pattern  420  can be connected to the printed circuit board. The conductive epoxy  440  serves as an adhesive to enhance a physical bond between the conductive via  450  and the conductive pattern  420 . 
       FIGS. 5A through 5D  are cross-sectional views sequentially illustrating a method of manufacturing a mobile communication terminal case according to still another exemplary embodiment of the invention. 
     In  FIG. 5A , a conductive pattern  520  is formed on a carrier film  530 . 
     The carrier film  530  has an antenna pattern on one surface thereof or antenna patterns on both surfaces thereof, and is inserted into a mold to perform an in-molding process. Therefore, the carrier film  530  needs to be a material that does not undergo significant deformation under the pressure and temperature during the in-molding labeling, and at the same time, can be formed integrally with the case of the mobile communication terminal. Preferably, the carrier film may include a thin, insulating polymer material. 
     The conductive pattern  520  may be formed by using various kinds of methods. First, a conductive pattern may be printed onto the carrier film  530  by using conductive ink. Alternatively, a desired pattern may be directly formed on the carrier film by sputtering or evaporation. The conductive pattern  520  may be formed of previously manufactured metal foil which is then attached to the carrier film  530 . 
     In this embodiment, the conductive pattern  520  is formed on one surface of the carrier film  530 . However, conductive patterns may be formed on both surfaces of the carrier film  530 . Here, the conductive patterns formed on the carrier film may be symmetrical with each other to form an antenna having a balanced structure. 
     In  FIG. 5B , a conductive via  550  that is connected to the conductive pattern  520  formed on the carrier film  530  is formed. 
     Conductive epoxy  540  may be used to connect the conductive via  550  to the conductive pattern  520 . In this embodiment, the conductive via  550  may have a cylindrical shape having an opening  551 . Therefore, when the opening  551  is filled with the conductive epoxy  540 , the conductive epoxy  540  is cured and adheres to each of the conductive via  550  and the conductive pattern  520 . The conductive epoxy  540  can provide a stable connection between the conductive via  550  and the conductive pattern  520 . Here, when the conductive epoxy  540  fills the opening  550 , the conductive epoxy  540  may partially fill the opening  550 . The conductive via  550  may be in direct contact to the conductive pattern  520  or be connected to the conductive pattern  520  through the conductive epoxy  540 . 
     The conductive via may have various shapes, and be simply formed into a conductive line. Here, conductive epoxy that is in contact with each of the conductive via and the conductive pattern is used to enhance a connection between the conductive via and the conductive pattern. 
     In  FIG. 5C , the carrier film having the conductive pattern formed thereon and the conductive via, connected to the conductive pattern, formed therein are inserted into the mold for manufacturing the case of the mobile communication terminal, and a molding material is injected into the mold, thereby manufacturing a case body of the terminal. 
     Referring to  FIG. 5C , the carrier film  530  having the conductive pattern  520  formed thereon and the conductive via  550  formed therein may be inserted into the mold  560 . The mold  560  may include a first part  561 , a second part  562 , and a third part  563 . The first part  561  is in contact with the carrier film  530  and forms a lower surface of the mold. A molding material is injected into the second part  562 , which forms an upper surface of the mold. The third part  563  is connected to a storage unit containing the molding material. The carrier film  530  is inserted between the first part  561  and the second part  562  of the mold. The conductive pattern  520  formed on the carrier film may be disposed in direct contact with the molding material during the molding process. 
     All of the components are coupled with each other. The molding material is injected into the mold  560  though a nozzle under a predetermined pressure. The molding material may be a polymer-based material to manufacture the case of the terminal. The molding material injected into the mold fills space between the second part  562  and the first part  561  of the mold. 
       FIG. 5D  is a cross-sectional view illustrating a case body  510  of a mobile communication terminal. A cooling process and a curing process are performed after a compressing process of the mold  560 , such that the case body  510  of the mobile communication terminal has the conductive pattern  520  formed on one surface thereof and the conductive via  550 , connected to the conductive pattern  520 , formed therein can be manufactured. 
     In this embodiment, the method of manufacturing the case of the mobile communication terminal may further include filling the opening  551  of the conductive via with conductive epoxy. When the conductive via  550  has a cylindrical shape having the opening like this embodiment, an additional process of filling the opening  551  with the conductive epoxy  540  may be performed. 
     As set forth above, according to exemplary embodiments of the invention, a mobile communication terminal case that can provide a stable electrical connection between an antenna pattern formed on the outside of the mobile communication terminal case and a circuit board disposed inside the case, and prevent deformation of the antenna pattern can be obtained. 
     While the present invention has been shown and described in connection with the exemplary embodiments, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims.
