일반적인 이동 전화기의 헬리컬이나 다이폴 형태의 안테나는 외부에 돌출되어 있어서 휴대가 불편하기 때문에 요즘에는 이동 전회기의 등판에 플렉시블 PCB(printed circuit board)나 그것과 비슷한 재질의 PCB 기판을 사용한 마이크로 스트립 패치 안테나를 구비하여 감도가 높으며 휴대하기에 편리한 이동 전화기가 생산되고 있다.Since the helical or dipole type antenna of a typical mobile phone is protruded to the outside, it is inconvenient to carry, and nowadays, a microstrip patch antenna using a flexible printed circuit board (PCB) or a PCB substrate of a similar material is used on the back of the mobile telephone. With a high sensitivity and convenient to carry a mobile phone has been produced.
그러나, 이와 같이 등판을 사용한 안테나는 이동통신 단말기의 충전기가 착탈되는 면인 뒷면에 형성되는 방식으로 이는 충전기와 안테나가 서로 간섭을 일으켜 안테나의 이득을 떨어뜨릴 수 있다.However, the antenna using the back plate as described above is formed on the back surface of the mobile terminal detachable charger, which may interfere with each other and reduce the gain of the antenna.
본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 충전기와 안테나의 간섭을 방지하여 안테나의 이득 저하를 막을 수 있는 마이크로 스트립 패치 안테나를 구비한 이동통신 단말기를 제공하기 위한 것이다.The present invention is to solve the above problems, to provide a mobile communication terminal having a micro-strip patch antenna that can prevent the antenna and the antenna to reduce the gain by preventing interference with the charger.
도1은 본 발명의 실시예에 따른 마이크로 스트립 패치 안테나를 구비한 이동전화기의 정면도이다.1 is a front view of a mobile telephone having a micro strip patch antenna according to an embodiment of the present invention.
도2는 본 발명의 다른 실시예에 따른 마이크로 스트립 패치 안테나를 구비한 노트북 컴퓨터의 사시도이다.2 is a perspective view of a notebook computer with a microstrip patch antenna according to another embodiment of the present invention.
본 발명은 이와 같은 목적을 달성하기 위하여 마이크로 스트립 패치 안테나가 이동 통신 단말기의 외부와 접하는 표면에 설치되며, 특히 이동 전화기의 폴더(folder)나 플립(flip)에 설치되어 제공된다.In order to achieve the above object, the present invention provides a microstrip patch antenna installed on a surface of the mobile communication terminal which is in contact with the outside of the mobile communication terminal.
이와 본 발명의 이동통신 단말기는 신호를 무선으로 송수신하기 위한 무선 송수신부에 있어서, 무선 송수신부에 연결되는 마이크로 스트립 패치 안테나 및 마이크로 스트립 패치 안테나를 외부와 접하는 표면에 설치하기 위하여 표면에 설치되는 PCB를 포함한다.In addition, the mobile communication terminal of the present invention is a wireless transceiver for transmitting and receiving a signal wirelessly, the PCB is installed on the surface to install a micro strip patch antenna and a micro strip patch antenna connected to the wireless transceiver on the surface in contact with the outside It includes.
이 때, 상기 표면은 이동전화기의 폴더나 플립인 것을 특징으로 하고, 마이크로 스트립 패치 안테나가 설치된 PCB의 반대면은 접지된다.In this case, the surface is a folder or a flip of a mobile phone, and the opposite side of the PCB on which the micro strip patch antenna is installed is grounded.
이하, 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
이동 전화기는 전송하고자 하는 신호를 변조한 후, 필요한 주파수만을 선택하여 송신시의 공진 임피던스를 가지는 듀플렉서와 듀플렉서와 연결된 안테나를 통하여 송신하고, 안테나와 수신시의 공진 임피던스를 가지는 듀플렉서를 통하여 수신한 신호를 복조하여 무선 통신을 수행한다.After modulating the signal to be transmitted, the mobile phone selects only the required frequency and transmits it through the duplexer having the resonance impedance at the time of transmission and the antenna connected to the duplexer, and the signal received through the duplexer having the antenna and the resonance impedance at the reception. Demodulate to perform wireless communication.
이 때, 도1은 본 발명의 실시예에 따른 마이크로 스트립 패치 안테나를 구비한 이동전화기의 정면도이다.1 is a front view of a mobile telephone having a micro strip patch antenna according to an embodiment of the present invention.
도1에 도시된 바와 같이, 본 발명의 마이크로 스트립 패치 안테나를 구비한 이동 전화기는 폴더의 윗부분에 PCB(110)를 위치시키고, 이 PCB 위에 안테나의 면(120)을 위치시킨다.As shown in Fig. 1, a mobile phone having a microstrip patch antenna of the present invention places a PCB 110 on top of a folder, and positions the antenna face 120 on the PCB.
또한, 안테나의 커버리지를 극대화시키기 위하여 마이크로 스트립 패치 안테나를 폴더의 상면 전체에 형성하여 휴대 전화기가 사용자의 주머니나 가방 내에 위치할 때처럼 안테나의 방향이 전파의 간섭이 최대인 경우가 발생하더라도 휴대 전화기의 수신 감도에 영향을 최소로 줄일 수 있다.In addition, in order to maximize the coverage of the antenna, a microstrip patch antenna is formed on the entire upper surface of the folder so that even when the direction of the antenna is the largest, such as when the cellular phone is placed in a user's pocket or bag, The influence on the reception sensitivity of can be reduced to a minimum.
그리고, 이동 전화기 내부의 송수신 회로쪽으로 위치하는 마이크로 스트립 패치 안테나가 형성된 PCB(110)면의 반대면에는 접지면(도시하지 않음)이 형성되어 송수신 회로 쪽에는 영향을 훨씬 줄일 수 있도록 구성하였다.In addition, a ground plane (not shown) is formed on the opposite side of the PCB 110 surface on which the micro strip patch antenna located toward the transmission / reception circuit inside the mobile phone is configured to reduce the influence on the transmission / reception circuit much further.
이와 같은 마이크로 스트립 패치 안테나는 폴더형 이동 전화기뿐만 아니라 플립형 이동 전화기의 플립 윗부분에 설치될 수 있을 뿐만 아니라 무선 통신을 위하여 안테나를 필요로 하는 이동 단말기의 밧데리가 있는 표면 이외의 외부 표면에 형성될 수도 있다.Such a microstrip patch antenna may not only be installed on the flip top of a flip type mobile phone as well as a folding mobile phone, but may also be formed on an external surface other than the batteryd surface of a mobile terminal requiring an antenna for wireless communication. have.
도2는 본 발명의 다른 실시예에 따른 마이크로 스트립 패치 안테나를 구비한 노트북 컴퓨터의 사시도이다. 도2에 도시된 바와 같이, 노트북의 외부와 접하는 표면에 PCB(110)를 설치하고, 이 PCB 위에 마이크로 스트립 패치 안테나(120)를 형성한다. 물론, PCB(110)의 뒷면에는 접지면을 형성한다.2 is a perspective view of a notebook computer with a microstrip patch antenna according to another embodiment of the present invention. As shown in Fig. 2, the PCB 110 is installed on a surface of the notebook, and the micro strip patch antenna 120 is formed on the PCB. Of course, the back surface of the PCB 110 forms a ground plane.
이상에서 설명한 본 발명의 실시예는 하나의 실시예일 뿐 본 발명이 야기한 실시예에 한정되는 것은 아니며, 또한 상기 실시예 외에 많은 변경이나 변형이 가능한 것은 물론이다.The embodiments of the present invention described above are not limited to the embodiments caused by the present invention but only one embodiment, and many modifications and variations are possible besides the above embodiments.
예를 들어, 본 발명의 마이크로 스트립 안테나는 이동 전화기 및 노트북 컴퓨터뿐만 아니라 무선 통신을 위하여 안테나를 필요로 하는 모든 이동 통신 단말기에 적용할 수 있다. 즉, 이동 통신 단말기의 외부와 접하는 면에 마이크로 스트립 패치 안테나를 설치하여 사용할 수 있다.For example, the microstrip antenna of the present invention can be applied not only to mobile telephones and notebook computers, but also to all mobile communication terminals requiring an antenna for wireless communication. That is, the microstrip patch antenna may be installed and used on the surface contacting the outside of the mobile communication terminal.
