Description

안테나 패키지Antenna package
본 발명은 안테나 패키지에 관한 것으로, 보다 상세하게는 휴대폰 단말기와 같은 전자 장치에서 외장 케이스의 표면에 쉽게 부착 가능한 안테나 패키지에 관한 것이다.The present invention relates to an antenna package, and more particularly, to an antenna package that can be easily attached to the surface of an external case in an electronic device such as a mobile phone terminal.
안테나(antenna)는 특정 영역대의 전자기파를 송신 혹은 수신하기 위한 변환장치이다. 안테나는 라디오 주파수대의 전기 신호를 전자기파로 바꾸어 발신하거나 그 반대로 전자기파를 전기 신호로 바꾸는 역할을 한다. 라디오나 텔레비전 등 방송과 전파를 이용한 무전기, 무선LAN 양방향 커뮤니케이션 장치 등에 널리 쓰이고 있으며, 최근에는 휴대폰 단말기와 같은 전자 장치의 외장 케이스에 구비되어 많이 쓰이고 있다.An antenna is a conversion device for transmitting or receiving electromagnetic waves in a specific area. The antenna converts electrical signals in the radio frequency band into electromagnetic waves and transmits them, or vice versa, converts electromagnetic waves into electrical signals. It is widely used in radio and television, such as radios using broadcast and radio waves, and wireless LAN two-way communication devices. Recently, it has been widely used in external cases of electronic devices such as mobile phones.
이와 같은 안테나를 휴대폰 단말기와 같은 전자 장치의 외장 케이스에 형성할 때, 외장 케이스를 형성하기 위한 폴리프로필렌(Polypropylene, PP)과 안테나 패턴을 형성하기 위한 ABS 수지(acrylonitrile butadiene styrene copolymer)를 이용하여, 안테나 패턴을 갖는 ABS 수지가 폴리프로필렌 재질의 외장 케이스의 표면에 형성되도록 이중 사출을 수행한 후, 에칭조에 이중 사출된 외장 케이스를 함입하여 ABS 수지를 에칭한 후, ABS 수지가 에칭되어 형성된 홈에 안테나 금속층을 도금하여 형성함으로써, 외장 케이스의 표면에 안테나 패턴을 형성하였다.When such an antenna is formed in an external case of an electronic device such as a mobile phone terminal, polypropylene (PP) for forming the external case and ABS resin (acrylonitrile butadiene styrene copolymer) for forming the antenna pattern are used. After performing double injection so that the ABS resin having the antenna pattern is formed on the surface of the polypropylene outer case, the ABS resin is etched by inserting the double injection case into the etching bath, and then the ABS resin is etched into the formed groove. By plating and forming the antenna metal layer, an antenna pattern was formed on the surface of the outer case.
그러나, 이와 같은 안테나 제조 방법은 휴대폰 단말기의 설계 변경에 따라 외장 케이스의 형태가 변할 때마다 금형을 새로 제작해야 하는 등 제조 원가가 증가하는 문제점이 있었다.However, such an antenna manufacturing method has a problem in that manufacturing cost increases, such as having to newly manufacture a mold whenever the shape of an external case changes according to a design change of a mobile phone terminal.
이와 같은 제조 원가에 관련된 문제점을 해소하기 위하여 LDS(Laser Direct Structuring) 원리를 이용하여, 수지재에 금속 물질의 LDS 첨가물이 함유된 LDS용 수지재로 외장 케이스 형태의 베이스를 사출한 이후, 레이저로 외장 케이스 형태의 베이스 표면에 레이저(Laser)를 조사하여 금속 핵이 노출되도록 안테나 패턴을 형성한 이후, 안테나 패턴 상에 노출된 금속 핵을 도금 시드층으로 이용하여, 안테나 금속층을 도금함으로써 형성하였다.In order to solve such problems related to manufacturing cost, using the LDS (Laser Direct Structuring) principle, after injecting the base in the form of an outer case with a resin material for LDS containing the LDS additive of a metallic material in the resin material, After forming the antenna pattern so that the metal nuclei are exposed by irradiating a laser on the outer case-shaped base surface, the metal core exposed on the antenna pattern was used as a plating seed layer, and the antenna metal layer was plated.
그러나, 최근에는 휴대폰 단말기와 같은 전자 장치의 통신 방식이 다양해짐에 따라, 다양한 주파수 대역에 대응이 가능하도록 하기 위하여 안테나의 개수가 증가하게 되었다.However, in recent years, as communication methods of electronic devices such as mobile phone terminals are diversified, the number of antennas has increased in order to be able to respond to various frequency bands.
그러나, 이와 같이 안테나의 개수가 증가하면서, 케이스의 표면에 안테나를 형성하기 위한 영역이 상대적으로 감소하고, 필요한 안테나의 길이와 면적을 확보하기 위하여 일부는 전술한 바와 같은 LDS 방식으로 제조한 안테나를 사용하고, 일부 부족한 안테나 길이에 대해서는 케이스의 측면 또는 곡면이 형성된 부분에 추가적으로 형성하였다.However, as the number of antennas increases, the area for forming an antenna on the surface of the case is relatively reduced, and in order to secure the required length and area of the antenna, some antennas manufactured by the LDS method as described above are used. And, for some insufficient antenna length, it was additionally formed on the side of the case or on the curved part.
이와 같이 부족한 안테나의 길이를 확보하기 위해 형성되는 안테나 금속층은 정해진 베이스 영역이 구비되지 않아, 폴리 이미드(Polyimide, PI) 필름 또는 연성 인쇄 회로 기판(Flexible Printed Circuit Board, FPCB) 상에 형성된 안테나 패턴을 형성한 이후, 안테나 패턴이 형성된 PI 필름이나 FPCB 필름을 케이스의 측면 또는 곡면이 형성된 부분에 부착하는 방식으로 부족한 안테나의 길이를 확보하였다.The antenna metal layer formed to secure the insufficient length of the antenna as described above does not have a predetermined base area, so an antenna pattern formed on a polyimide (PI) film or a flexible printed circuit board (FPCB) After forming, the length of the insufficient antenna was secured by attaching the PI film or the FPCB film on which the antenna pattern was formed to the side or curved portion of the case.
그러나, 이와 같이, 케이스의 측면 또는 곡면이 형성된 부분에 부착하는 방식으로 형성된 안테나는 PI 필름이나 FPCB 필름의 탄성 복원력 또는 필름 굽힘 탄성 계수가 상대적으로 커, 시간이 지남에 따라 케이스에서 탈락되는 등의 문제가 있었다.However, in this way, the antenna formed by attaching to the side or curved portion of the case has a relatively large elastic restoring force or film bending elastic modulus of the PI film or the FPCB film, so that it is removed from the case over time. There was a problem.

도 1에 도시된 바와 같이, 본 발명에 따른 안테나 패키지는 베이스 필름층(100), 점착제층(200) 및 안테나 금속층(300)을 포함할 수 있으며, 안테나 금속층(300) 위에 안테나 금속층(300)을 보호하기 위한 바디 필름층(400)이 선택적으로 더 구비될 수 있다.As shown in FIG. 1, the antenna package according to the present invention may include a base film layer 100, an adhesive layer 200 and an antenna metal layer 300, and an antenna metal layer 300 on the antenna metal layer 300. A body film layer 400 for protecting it may be optionally further provided.
베이스 필름층(100) 은 점착제층(200)과 안테나 금속층(300)을 지지하여, 안테나 금속층(300)의 패턴이 훼손되는 것을 방지하고, 안테나 금속층(300)이 휴대폰 단말기와 같은 전자 장치에 적용되기 전까지 안테나 금속층(300) 및 점착제층(200)을 보호할 수 있다.The base film layer 100 supports the adhesive layer 200 and the antenna metal layer 300 to prevent the pattern of the antenna metal layer 300 from being damaged, and the antenna metal layer 300 is applied to electronic devices such as mobile phones. The antenna metal layer 300 and the pressure-sensitive adhesive layer 200 may be protected until it is formed.
점착제층(200)은 베이스 필름 위에 위치하여, 안테나 금속층(300)이 휴대폰 단말기와 같은 전자 장치에 적용될 때, 안테나 금속층(300)과 점착제층(200)을 베이스 필름으로부터 분리하여 휴대폰 단말기의 케이스 등에 부착할 때, 점착제층(200)은 안테나 금속층(300)을 케이스에 부착시키는데, 사용될 수 있다. The adhesive layer 200 is located on the base film, and when the antenna metal layer 300 is applied to an electronic device such as a mobile phone terminal, the antenna metal layer 300 and the adhesive layer 200 are separated from the base film to When attaching, the pressure-sensitive adhesive layer 200 may be used to attach the antenna metal layer 300 to the case.
안테나 금속층(300)은 점착제층(200) 위에 위치하고, 외부로부터 입사되는 전자기장에 의해 유도 전류를 발생시키는 안테나 전극 패턴을 구비할 수 있으며, 휴대폰 단말기와 같은 전자 장치에 적용되어, 안테나로서의 역할을 수행할 수 있다.The antenna metal layer 300 is located on the pressure-sensitive adhesive layer 200 and may have an antenna electrode pattern that generates an induced current by an electromagnetic field incident from the outside, and is applied to an electronic device such as a mobile phone terminal, and serves as an antenna. can do.
이와 같은 안테나 금속층(300)은 제1 산화 방지층(320A), 코어 금속층(310) 및 제2 산화 방지층(320B)을 구비할 수 있다.The antenna metal layer 300 may include a first oxidation prevention layer 320A, a core metal layer 310 and a second oxidation prevention layer 320B.
제1 산화 방지층(320A)은 점착제층(200) 위에 위치하고 제1 재질의 금속을 포함할 수 있으며, 코어 금속층(310)은 제1 산화 방지층(320A) 위에 위치하고, 제1 재질과 다른 제2 재질의 금속을 포함할 수 있고, 제2 산화 방지층(320B)은 코어 금속층(310) 위에 위치하고, 제1 재질의 금속을 포함할 수 있다. 이와 같은 제1, 2 산화 방지층(320A, 320B)은 코어 금속층(310)의 표면에 도금 방식으로 형성될 수 있다.The first oxidation prevention layer 320A is located on the pressure-sensitive adhesive layer 200 and may include a metal of a first material, and the core metal layer 310 is located on the first oxidation prevention layer 320A, and a second material different from the first material May include a metal of, and the second oxidation prevention layer 320B is positioned on the core metal layer 310, and may include a metal of a first material. The first and second anti-oxidation layers 320A and 320B may be formed on the surface of the core metal layer 310 by a plating method.
이와 같이, 본 발명에 따른 안테나 금속층(300)은 코어 금속층(310)의 상부면 및 하부면에 제1, 2 산화 방지층(320A, 320B)을 구비하여, 코어 금속층(310)이 산화되는 것을 방지할 수 있어, 안테나가 외부의 공기나 습기에 의해 산화되어, 안테나의 수신 특성이 저하되는 것을 방지할 수 있다.As described above, the antenna metal layer 300 according to the present invention includes first and second oxidation prevention layers 320A and 320B on the upper and lower surfaces of the core metal layer 310 to prevent the core metal layer 310 from being oxidized. In this way, it is possible to prevent the antenna from being oxidized by external air or moisture and deteriorating the reception characteristics of the antenna.
이를 위해, 제1 산화 방지층(320A) 및 제2 산화 방지층(320B) 각각은 코어 금속층(310)보다 산화력이 낮을 수 있다.To this end, each of the first oxidation prevention layer 320A and the second oxidation prevention layer 320B may have lower oxidizing power than the core metal layer 310.
이와 같은 코어 금속층(310)의 재질은 전도성이 상대적으로 좋은 구리(Cu)를 포함할 수 있으며, 제1 산화 방지층(320A) 및 제2 산화 방지층(320B)의 재질은 산화력이 상대적으로 낮은 니켈(Ni)을 포함할 수 있다.The material of the core metal layer 310 may include copper (Cu) having relatively good conductivity, and the material of the first oxidation prevention layer 320A and the second oxidation prevention layer 320B is nickel ( Ni) may be included.
그러나, 코어 금속층(310)의 재질과 제1, 2 산화 방지층(320A, 320B)의 재질이 반드시 이에 한정되는 것은 아니고, 코어 금속층(310)의 재질보다 산화력이 낮은 금속층이라면, 제1, 2 산화 방지층(320A, 320B)의 재질로 어떠한 것이라도 사용 가능하다.However, the material of the core metal layer 310 and the material of the first and second anti-oxidation layers 320A and 320B are not necessarily limited thereto, and if a metal layer having a lower oxidizing power than the material of the core metal layer 310, the first and second oxidation Any material may be used for the prevention layers 320A and 320B.
여기서, 코어 금속층(310)의 두께(T310)는 제1, 2 산화 방지층(320A, 320B)의 두께(T320A, T320B)보다 클 수 있다. 이와 같이 전도성이 상대적으로 좋은 코어 금속층(310)의 두께(T310)를 제1, 2 산화 방지층(320A, 320B)의 두께(T320A, T320B)보다 크게 함으로써, 코어 금속층(310)에 의한 안테나의 수신 특성을 최상의 상태로 유지할 수 있다.Here, the thickness T310 of the core metal layer 310 may be greater than the thicknesses T320A and T320B of the first and second antioxidant layers 320A and 320B. As described above, by making the thickness (T310) of the core metal layer 310 having relatively good conductivity larger than the thicknesses (T320A, T320B) of the first and second oxidation prevention layers (320A, 320B), reception of the antenna by the core metal layer 310 The characteristics can be kept in the best condition.
일례로, 제1, 2 산화 방지층(320A, 320B) 각 두께는 코어 금속층(310) 두께의 0.02배 내지 0.19배 사이일 수 있다. For example, the thickness of each of the first and second antioxidant layers 320A and 320B may be between 0.02 and 0.19 times the thickness of the core metal layer 310.
여기서, 제1, 2 산화 방지층(320A, 320B) 각 두께를 코어 금속층(310) 두께의 0.02배 이상으로 하는 것은 코어 금속층(310)의 산화를 방지하기 위한 최소한의 값이고, 제1, 2 산화 방지층(320A, 320B) 각 두께를 코어 금속층(310) 두께의 0.19배 이하로 하는 것은 코어 금속층(310)의 산화를 방지하는 기능을 수행하면서, 제1, 2 산화 방지층(320A, 320B)을 형성하는 공정 시간과 공정 비용을 최소화하기 위함이다. Here, the thickness of each of the first and second anti-oxidation layers 320A and 320B is 0.02 or more times the thickness of the core metal layer 310 is a minimum value for preventing oxidation of the core metal layer 310, and the first and second oxidation Making each thickness of the prevention layers 320A and 320B less than 0.19 times the thickness of the core metal layer 310 forms the first and second oxidation prevention layers 320A and 320B while performing a function of preventing oxidation of the core metal layer 310 This is to minimize the process time and process cost.
일례로, 코어 금속층(310)은 8㎛ ~ 24㎛ 사이로 형성될 수 있으며, 제1, 2 산화 방지층(320A, 320B)은 0.5㎛ ~ 1.5㎛ 사이로 형성될 수 있다.For example, the core metal layer 310 may be formed in a range of 8 μm to 24 μm, and the first and second oxidation prevention layers 320A and 320B may be formed in a range of 0.5 μm to 1.5 μm.
점착제층(200)과 제1 산화 방지층(320A) 사이의 점착력은 점착제층(200)과 베이스 필름층(100) 사이의 점착력보다 클 수 있다.The adhesive force between the pressure-sensitive adhesive layer 200 and the first antioxidant layer 320A may be greater than that between the pressure-sensitive adhesive layer 200 and the base film layer 100.
점착제층(200)과 제1 산화 방지층(320A) 사이의 점착력이 점착제층(200)과 베이스 필름층(100) 사이의 점착력과 동일하거나 더 작은 경우, 안테나 금속층(300)을 휴대폰 단말기와 같은 전자 장치에 적용하기 위해, 안테나 금속층(300)을 베이스 필름으로부터 분리할 때, 점착제층(200)이 제1 산화 방지층(320A)으로부터 쉽게 분리되어, 공정이 지연되거나 공정에 방해가 될 수 있다.When the adhesive force between the pressure-sensitive adhesive layer 200 and the first antioxidant layer 320A is equal to or less than the adhesive force between the pressure-sensitive adhesive layer 200 and the base film layer 100, the antenna metal layer 300 is used as an electronic device such as a mobile phone terminal. For application to the device, when separating the antenna metal layer 300 from the base film, the pressure-sensitive adhesive layer 200 is easily separated from the first antioxidant layer 320A, so that the process may be delayed or the process may be disturbed.
그러나, 본 발명과 같이, 점착제층(200)과 제1 산화 방지층(320A) 사이의 점착력을 점착제층(200)과 베이스 필름층(100) 사이의 점착력보다 크게 함으로써, 안테나 금속층(300)을 휴대폰 단말기와 같은 전자 장치에 적용하기 위해, 안테나 금속층(300)을 베이스 필름으로부터 분리할 때, 점착제층(200)이 제1 산화 방지층(320A)으로부터 분리되는 것을 최소화할 수 있고, 공정 효율을 보다 증가시킬 수 있다.However, as in the present invention, by making the adhesive force between the pressure-sensitive adhesive layer 200 and the first antioxidant layer 320A greater than the adhesive force between the pressure-sensitive adhesive layer 200 and the base film layer 100, the antenna metal layer 300 is transferred to the mobile phone. For application to electronic devices such as terminals, when separating the antenna metal layer 300 from the base film, it is possible to minimize the separation of the pressure-sensitive adhesive layer 200 from the first antioxidant layer 320A, and further increase the process efficiency. I can make it.
점착제층(200)은 상온에서 압력에 의해 점착되는 감압성 접착제(Pressure sensitive adhesive, PSA)를 포함할 수 있다. 감압성 접착제는 상온에서 점성을 보유하고, 가벼운 압력으로 쉽게 접착될 수 있어, 안테나 금속층(300)을 휴대폰 단말기의 케이스에 접착시킬 때, 접착을 위한 별도의 열처리 공정을 요구하지 않고, 가벼운 압력으로 접착 공정을 쉽게 수행할 수 있다.The pressure-sensitive adhesive layer 200 may include a pressure sensitive adhesive (PSA) that is adhered by pressure at room temperature. The pressure-sensitive adhesive retains viscosity at room temperature and can be easily bonded with light pressure, so when bonding the antenna metal layer 300 to the case of a mobile phone terminal, it does not require a separate heat treatment process for bonding, but with light pressure. The bonding process can be easily carried out.
이와 같은 감압성 접착제(PSA)를 접착제층(200)으로 사용하면, 접착제층(200)의 접착력을 보다 더 향상시킬 수 있다.When such a pressure-sensitive adhesive (PSA) is used as the adhesive layer 200, the adhesive strength of the adhesive layer 200 may be further improved.
보다 구체적으로, 감압성 접착제(PSA)는 재질 특성상 압력에 의해 점착 또는 부착될 수 있어, 감압성 접착제(PSA)가 접착제층(200)으로 형성된 안테나 금속층(300)을 곡면이 형성된 휴대폰 단말기의 케이스의 부분에 접착시켰을 때, 감압성 접착제(PSA)의 두께는 전체적으로 5% ~ 10% 정도 압착될 수 있다.More specifically, the pressure-sensitive adhesive (PSA) may be adhered or attached by pressure due to the nature of the material, so that the antenna metal layer 300 formed of the adhesive layer 200 with the pressure-sensitive adhesive (PSA) is a case of a mobile phone terminal in which a curved surface is formed. When bonded to a portion of the pressure-sensitive adhesive (PSA), the overall thickness of the pressure-sensitive adhesive (PSA) can be compressed by about 5% to 10%.
이와 같은 감압성 접착제(PSA)의 압착은 감압성 접착제의 접착력을 보다 더 향상시킬 수 있으며, 휴대폰 단말기의 케이스의 곡면 부분에 접착되었을 때, 탄성 복원력에 의해 안테나 금속층(300)이 휴대폰 단말기의 케이스로부터 분리되어 떨어지는 것을 억제할 수 있다.When the pressure-sensitive adhesive (PSA) is pressed, the adhesive strength of the pressure-sensitive adhesive can be further improved, and when it is adhered to the curved portion of the case of the mobile phone terminal, the antenna metal layer 300 is applied to the case of the mobile phone terminal due to the elastic restoring force. Separation from and falling can be suppressed.
일례로, 점착제층(200)은 베이스 필름층(100)에 점착되는 제1 감압성 점착제층(220A), 제1 감압성 점착제층(220A) 위에 위치하는 점착 베이스층(210) 및 점착 베이스층(210) 위에 위치하여, 제1 산화 방지층(320A)에 점착되는 제2 감압성 점착제층(220B)을 포함할 수 있다.For example, the pressure-sensitive adhesive layer 200 includes a first pressure-sensitive adhesive layer 220A adhered to the base film layer 100, an adhesive base layer 210 and an adhesive base layer positioned on the first pressure-sensitive adhesive layer 220A.
