Description

무선통신단말기용 인테나 및 그 제조방법{Intenna for Wireless Communication Terminal and Manufacturing Method thereof}TECHNICAL FIELD [0001] The present invention relates to an intenna for a wireless communication terminal,

본 발명은 무선통신단말기용 인테나 및 그 제조방법에 관한 것으로서, 보다 상세하게는 휴대폰 등의 무선통신단말기의 본체 내부에 내장되는 안테나 즉, 내장형 안테나에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intenna for a wireless communication terminal and a method of manufacturing the same. More particularly, the present invention relates to an antenna embedded in a main body of a wireless communication terminal such as a mobile phone.

안테나는 무선통신단말기 본체(이하 "본체"라고 함)에 설치되는 위치에 따라 본체 외부로 노출되도록 설치되는 외장형 안테나와, 본체의 내부에 설치되는 내장형 안테나(인테나)로 구분할 수 있다.The antenna can be divided into an external antenna that is installed to be exposed to the outside of the body according to a position of the wireless communication terminal (hereinafter, referred to as "body"), and an internal antenna (internal antenna) that is installed inside the body.

무선통신단말기용 인테나는 기본적으로 방사체 기능을 수행하는 방사패턴부를 구비하고 있는 데, 이 방사패턴부가 외부에 노출되는 경우 방사패턴부가 외부충격에 의해 변형되어 방사특성이 저하되고 외관이 나빠지기 때문에 방사패턴부가 외부로 노출되지 않는 무선통신단말기용 인테나가 안출되어 사용되고 있다.The intenna for a wireless communication terminal basically includes a radiation pattern portion that performs a radiator function. When the radiation pattern portion is exposed to the outside, the radiation pattern portion is deformed by an external impact to lower the radiation characteristic and deteriorate the appearance, The intenna for the wireless communication terminal in which the pattern portion is not exposed to the outside is being used.

도7 및 도8은 각각 종래 무선통신단말기용 인테나의 결합사시도이고, 도9는 종래 무선통신단말기용 인테나의 요부단면도이고, 도10은 종래 무선통신단말기용 인테나의 패턴부의 사시도이다. FIG. 9 is a cross-sectional view of a main portion of an intenna for a conventional wireless communication terminal, and FIG. 10 is a perspective view of a pattern portion of a conventional intenna for a wireless communication terminal.

종래의 무선통신단말기용 인테나는, 이들 도면에 도시된 바와 같이, 패턴홀더(120)와, 패턴홀더(120)에 설치된 도전재질의 방사체(110)를 갖고 있다.As shown in these drawings, a conventional intenna for a wireless communication terminal has a pattern holder 120 and a radiator 110 made of a conductive material and provided in the pattern holder 120.

패턴홀더(120)는 홀더바디부(121)와, 홀더바디부(121)의 상면에 적층 형성된 보호층부(122)를 갖고 있다.The pattern holder 120 has a holder body part 121 and a protective layer part 122 laminated on the upper surface of the holder body part 121.

보호층부(122)의 상면이 홀더상면을 형성하고, 홀더바디부(121)의 측면과 보호층부(122)의 측면이 합해져서 홀더측면을 형성하게 된다.The upper surface of the protective layer portion 122 forms the upper surface of the holder and the side surface of the holder body portion 121 and the side surface of the protective layer portion 122 are combined to form the side surface of the holder.

방사체(110)는 방사체 기능을 수행하는 방사패턴부(111)와, 방사패턴부(111)의 종단에 형성된 급전단자(112)와, 방사패턴부(111)로부터 분기 형성된 접지패턴부(113)와, 접지패턴부(113)의 종단에 형성된 접지단자(114)를 갖고 있다.The radiator 110 includes a radiation pattern portion 111 for performing a radiator function, a power supply terminal 112 formed at the end of the radiation pattern portion 111, a ground pattern portion 113 branched from the radiation pattern portion 111, And a grounding terminal 114 formed at the end of the grounding pattern portion 113.

방사패턴부(111)는 급전단자(112)의 인접영역이 절곡되어 있고, 전체적으로 판형태로 형성된다.The radiation pattern portion 111 has an adjacent region of the power supply terminal 112 bent and is formed in a plate shape as a whole.

그리고 방사패턴부(111)는 특정 주파수대의 수신특성을 향상시키기 위해 홀더측면에 배치되는 측면방사패턴부(111c)를 갖고 있다. The radiation pattern portion 111 has a side radiation pattern portion 111c disposed on the holder side surface to improve reception characteristics in a specific frequency band.

이러한 구성을 갖는 방사패턴부(111)는 무선통신단말기의 송신부로부터 전달되는 송신신호를 공중으로 방사하고, 공중으로부터 전달되는 수신신호를 수령하여 무선통신단말기의 수신부로 전달하는 기능을 수행한다.The radiation pattern unit 111 having such a configuration radiates a transmission signal transmitted from the transmission unit of the wireless communication terminal to the air and receives the reception signal transmitted from the air and transmits the reception signal to the reception unit of the wireless communication terminal.

접지패턴부(113)는 접지단자(114)의 인접영역이 절곡되어 있다.The ground pattern portion 113 has an adjacent region of the ground terminal 114 bent.

이러한 구성을 갖는 방사체(110)는 방사패턴바디부(111a)가 홀더바디부(121)의 상면과 보호층부(122)의 저면 사이에 배치되고, 급전단자(112)가 패턴홀더(120)의 저면을 통해 노출되도록 패턴홀더(120)에 설치된다.The radiating element 110 having such a configuration is arranged such that the radiation pattern body portion 111a is disposed between the upper surface of the holder body portion 121 and the bottom surface of the protective layer portion 122 and the power supply terminal 112 is connected to the pattern holder 120 And is installed in the pattern holder 120 so as to be exposed through the bottom surface.

전술한 구성을 갖는 종래의 인테나를 제작하는 방법을 도11과 도12를 참조하여 설명하면 다음과 같다.A method of manufacturing a conventional intenna having the above-described structure will be described with reference to FIGS. 11 and 12. FIG.

방사체형성단계Emitter formation step

도전성이 양호한 금속을 사용하여 프레스 가공 등의 방법으로 전술한 구성을 갖는 방사체(110)를 형성한다.The radiator 110 having the above-described configuration is formed by a method such as press working using a metal having good conductivity.

금형제작단계Mold production stage

홀더바디부(121)의 외관에 대응하는 사출금형캐비티(131)가 형성되어 있고, 사출금형캐비티(131)의 내부에 설치된 방사체(110)를 지지하기 위한 인서트물지지수단을 갖는 사출금형을 제작한다.An injection mold cavity 131 corresponding to the outer surface of the holder body 121 is formed and an injection mold having an insert water holding means for supporting the radiator 110 installed in the injection mold cavity 131 is manufactured do.

여기서 인서트물지지수단은 방사패턴부(111)의 상면이 사출금형캐비티(131)의 내표면에 접촉하도록 마련된다(도11 참조).Here, the insert water holding means is provided so that the upper surface of the radiation pattern portion 111 is in contact with the inner surface of the injection mold cavity 131 (see FIG. 11).

그리고 인서트물지지수단은 접지단자(114), 급전단자(112) 및 측면방사패턴부(111c)의 일부가 사출금형캐비티(131)의 내표면에 접촉하고, 사출성형 완료 후 방사패턴부(111)의 절곡영역과 접지패턴부(113)의 절곡영역이 패턴홀더(120)를 통과하는 위치에 배치되게 방사체(110)를 지지할 수 있도록 마련된다.The insert water holding means is configured such that a part of the ground terminal 114, the power supply terminal 112 and the side radiation pattern portion 111c is in contact with the inner surface of the injection mold cavity 131 and the radiation pattern portion 111 And the bending region of the ground pattern portion 113 are disposed at positions passing through the pattern holder 120 so as to support the radiator 110.

인서트물지지수단은 종래 알려진 바와 같이 고정핀(132), 슬라이드코어 등을 사용하여 구현할 수 있다.The insert water holding means can be realized by using a fixing pin 132, a slide core or the like as is known in the art.

고정핀(132)에 의해 홀더바디부(121)과 방사패턴부(111)에는 각각 홀더핀공(도시되지 않음)과 패턴부핀공(도시되지 않음)이 형성된다.A holder pin hole (not shown) and a pattern pin hole (not shown) are formed in the holder body part 121 and the radiation pattern part 111 by the fixing pin 132, respectively.

홀더바디부성형단계Holder body part molding step

방사체(110)가 사출금형캐비티(131)의 내부에 인서트물로 설치된 상태에서 사출금형캐비티(131)에 용융된 합성수지(Polycabonate, ABS 등)를 주입하여 홀더바디부(121)를 사출성형한다(도12 참조).The molten synthetic resin (ABS resin, etc.) is injected into the injection mold cavity 131 in a state where the radiator 110 is inserted into the injection mold cavity 131 as an insert material, and the holder body part 121 is injection molded 12).

보호층부형성단계Protective layer forming step

홀더바디부(121)의 상면에 우레탄 코팅이나 UV 코팅 등의 방식을 채용하여 보호층부(122)를 형성한다.A protective layer 122 is formed on the upper surface of the holder body 121 by employing a method such as urethane coating or UV coating.

전술한 구성을 갖는 종래의 인테나는 급전단자(112)가 메인피시비의 급전연결패턴에 전기적으로 접촉하고, 접지단자(114)가 접지판 또는 메인피시비의 접지영역에 전기적으로 연결되도록 무선통신단말기의 본체에 설치된다. 메인피시비의 급전연결패턴은 커넥터를 통해 무선처리부의 송신부 및 수신부에 전기적으로 연결되어 있다.In the conventional intenna having the above-described configuration, the power supply terminal 112 is electrically connected to the power supply connection pattern of the main PCB and the ground terminal 114 is electrically connected to the ground region of the main PCB And is installed in the main body. The feed connection pattern of the main PCB is electrically connected to the transmitting section and the receiving section of the radio processing section via the connector.

그런데 종래의 무선통신단말기용 인테나에 따르면, 홀더바디부(121)를 사출성형공정을 통해 형성한 후 다시 방사패턴부(111)의 노출을 방지하기 위해 보호층부(122)를 홀더바디부(121)에 코팅 등의 방법으로 형성하여야 하기 때문에 제조공정이 복잡하다는 문제점이 있었다.However, according to the conventional intenna for a wireless communication terminal, after the holder body part 121 is formed through the injection molding process, the protection layer part 122 is attached to the holder body part 121 ), It has a problem that the manufacturing process is complicated.

그리고 보호층부(122)를 형성할 때 보호층부(122)의 두께 즉, 방사패턴부(111)의 매설깊이를 감소시키기 어렵다는 문제점이 있었다. 이에 따라 방사패턴부(111)의 매설깊이가 증가하여 방사패턴부(111)의 방사특성이 저하된다는 2차적인 문제점이 발생한다.Further, there is a problem that it is difficult to reduce the thickness of the protective layer portion 122, that is, the depth of the radiation pattern portion 111 when the protective layer portion 122 is formed. As a result, the depth of embedment of the radiation pattern portion 111 is increased and the radiation characteristic of the radiation pattern portion 111 is lowered.

따라서 본 발명의 목적은, 제조공정이 간단해지고 방사패턴부의 매설깊이가 증가하는 것을 방지할 수 있도록 한 무선통신단말기용 인테나 및 그 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an intenna for a wireless communication terminal and a method of manufacturing the same, which can simplify the manufacturing process and prevent the buried depth of the radiation pattern portion from increasing.
