- Mobile communications terminals such as cellular phones, personal digital assistants (PDAs) and laptop computers, which support wireless communications, are indispensable devices in modern society. Functions including CDMA, wireless LANs, GSM and DMB have been added to these mobile communications terminals. One of the most important components that enable these functions to operate is associated with antennas.
- Antennas being used in these mobile communications terminals have advanced from external antennas, such as rod antennas or helical antennas, to internal antennas that are disposed inside of terminals.
- External antennas are susceptible to damage by external shock, while internal antennas increase the volume of terminals.
- In order to solve these problems, research has been undertaken to manufacture antennas that are formed integrally with mobile communications terminals.
- In order that antennas are formed integrally with terminals, a method of bonding flexible antennas to terminal bodies using adhesives is used. Recently, a method of forming antenna films by molding has been proposed.
- However, when flexible antennas are bonded by simply using adhesives, the reliability of these antennas is reduced as the adhesiveness decreases. Besides, this also causes harm to the appearance of the terminals, lessening emotional quality for consumers.
- In addition, when antenna films are used, product stability can be ensured. However, a process of bonding an antenna to a film is difficult to perform and manufacturing costs are also increased.
- Moreover, when such antenna films undergo a molding process, the elasticity of the antenna films makes it difficult to inject a molding solution into the mold while fixing the antenna films.
- Therefore, there is a need for studies to enable electronic device cases having antenna radiators embedded therein to be mass produced in a successive manner.

- Each of the antenna pattern portions may be connected with the radiator sheet by a support pin, and be separated from the radiator sheet after the injection-molding.
- A notch, a relief recess or the notch and the relief recess may be formed in a connection portion between the antenna pattern portion and the support pin, and serve to facilitate the separation of the antenna pattern portion from the support pin.
- The bending process and the injection-molding may be respectively performed by a bending mold and an injection mold by stages.
- The radiator sheet may be moved continuously by a supply reel and a pick-up reel.
- According to another aspect of the present invention, there is provided a method of manufacturing an antenna pattern frame, the method including: foiuiing radiator-sheet units by grouping antenna radiators arranged in the form of cells and including respective antenna pattern portions receiving an external signal; forming connection terminal portions of the antenna radiators of each radiator-sheet unit by using a bending process simultaneously or by stages; and injection-molding radiator frames such that the antenna pattern portions in the radiator-sheet unit are placed on one set of respective sides of the radiator frames and the connection terminal portions are placed on the other set of respective opposite sides of the radiator frames.
