Description
이동 무선기기의 안테나는 그 디자인을 이유로 하여 특별하게 요구되는 사항들이 있다. 특히 안테나가 외부로는 노출되지 않도록 케이스 안으로 통합될 수 있어야 한다. 이와 동시에 안테나는 적어도 2개의 상이한 주파수 범위 내에서 이용가능해야 하며 저렴하게 생산될 수 있어야 한다.Antennas for mobile radios have special requirements for their design. In particular, the antenna must be able to be integrated into the case so that it is not exposed to the outside. At the same time, the antenna must be available within at least two different frequency ranges and be able to be produced inexpensively.
현재 대부분의 이동 무선기기 안테나는 막대 안테나이며, 다시 말해서 외부에 노출된 안테나이다. 예컨대 통합된 안테나는 WO 95/24745호에 공지되어 있다. 그러나 이 공지된 기술은 매우 비싸고, 안테나의 크기가 크기 때문에 현재의 기기에는 설치할 공간적인 여유가 없다.Currently, most mobile radio antennas are rod antennas, that is, antennas exposed to the outside. Integrated antennas are known, for example, from WO 95/24745. However, this known technique is very expensive, and because of the large size of the antenna, there is no space for installation in current equipment.
본 발명은 통합가능한 듀얼-밴드-안테나에 관한 것이다.The present invention relates to an integrated dual-band antenna.
도 1은 본 발명에 해당하는 제 1 실시예를 도시한 개략도이고,1 is a schematic view showing a first embodiment corresponding to the present invention,
도 2는 본 발명에 해당하는 제 2 실시예를 도시한 개략도이며,Figure 2 is a schematic diagram showing a second embodiment corresponding to the present invention,
도 3 내지 도 5는 본 발명에 따른 안테나의 구체적인 실시예의 투시도이다.3 to 5 are perspective views of specific embodiments of the antenna according to the invention.
본 발명은 목적은, 안테나의 단부가 노출되지 않고, 통신 단말기 케이스 내에 통합될 수 있으며, 필요한 듀얼밴드 기능을 가진, 서문에서 언급한 종류의 안테나를 제시하는데 있다.It is an object of the present invention to provide an antenna of the kind mentioned in the preamble, with the end of the antenna not exposed, which can be integrated in the communication terminal case and which has the necessary dual band functionality.
본 발명의 목적을 달성하는데 있어서, 서문에서 언급한 안테나는 지표면 위에 위치하는, 대체로 직사각형의 전체 표면으로 구성되며, 이 전체 표면은 2개의독립된 주파수를 보내기 위하여 L자 모양의 역 F형 평면-안테나 (PIFA,Planar Inverted F Antenna) 및 직사각형의 역 F형 평면-안테나로 구성되며, 상기 역 F형 평면-안테나에는 도선을 경유하여 2개의 접점과 결합되어 있는 3개 또는 4개의 연결부가 구비된다.In order to achieve the object of the present invention, the antenna referred to in the preamble consists of a generally rectangular whole surface, located above the ground surface, which is an inverted F-shaped plane-antenna in the form of an L-shape to send two independent frequencies. (PLAN (Planar Inverted F Antenna) and a rectangular inverted F-plane antenna, and the inverted F-plane antenna is provided with three or four connections coupled to the two contacts via a conductor.
상기 제시한 문제점은 본 발명에 따라서 다음과 같은 안테나를 적용함으로써 해결되는데, 이 안테나는 특수한 도선 구조로 서로 결합되어 있는 2개의 PIFA-안테나 구조물을 공간적으로 설계함으로써 구성된다. 이로 인하여 듀얼밴드 적용에 적합하며, 평평하지 않은 표면 또는 둥근 모서리를 가진 케이스에도 알맞은 공간적으로 작은 구조물이 형성된다. 이 안테나는 통상적으로, 전자 장치를 금속적으로 차폐시키고 있는 필수 불가결한 금속표면으로부터 소수 mm의 간격을 두고서, 인접하여 작동된다.The problem presented above is solved by applying the following antenna according to the present invention, which is constructed by spatially designing two PIFA-antenna structures which are coupled to each other in a special conductor structure. This results in a spatially small structure suitable for dual band applications and suitable for cases with uneven surfaces or rounded corners. The antenna is typically operated adjacently, with a few millimeters spacing from the indispensable metal surface that is metallicly shielding the electronic device.
제작에 이용되는 판금 부분의 펀칭(punching) 및 벤딩(bending)에 대한 표준 기술은 매우 신속한 제조속도를 가능하게 하며, 이에 따라 제작비용 역시 저렴하다. 또한 안테나와 전자 장치를 전기적으로 접촉하게 하는 안테나 접촉 스프링의 제작비용을 절약할 수 있는데, 그 이유는 상기 안테나스프링이 한 단계의 제조 공정에서 안테나의 통합된 부분으로서 제작될 수 있기 때문이다.Standard techniques for the punching and bending of sheet metal parts used in fabrication allow for very fast manufacturing speeds and, therefore, low manufacturing costs. It is also possible to save the manufacturing cost of the antenna contact spring which makes the antenna and the electronic device in electrical contact, since the antenna spring can be manufactured as an integrated part of the antenna in one step manufacturing process.
상기 안테나는 제 1 공진주파수에 인접하여 타겟이 되는 주파수 대역중의 하나에 사용될 수 있으며(예를 들어 GSM; Global System for Mobile communication), 제 2 공진주파수에 인접하여 광대역적으로 운용됨으로써 그 밖의 주파수 대역에 사용될 수 있도록 활용된다(예를 들어 PCN; Point Cast Network 또는 PCS; PersonalCommunications Services). 또한 이와 동시에 약 50 오옴의 공칭 임피던스가 구현되어, 이 안테나가 정합 회로망(matching network) 없이도 또는 적은 수의 정합 소자만을 가지고도 작동될 수 있게 된다. 이것은 또한 정합 회로에서 늘 야기되는 손실을 피할 수 있는 결과를 가져온다.The antenna may be used in one of the target frequency bands adjacent to the first resonant frequency (e.g., GSM; Global System for Mobile communication), and is operated in a wide band adjacent to the second resonant frequency and thus other frequencies. Utilized for the band (e.g. PCN; Point Cast Network or PCS; Personal Communications Services). At the same time, a nominal impedance of about 50 ohms is also implemented, allowing the antenna to operate without a matching network or with only a few matching elements. This also results in avoiding the losses that are always caused in the matching circuit.
본 발명에 따른 공정은 양쪽의 부분 영역을 필수적으로 연결시킴으로써, 전체 시스템이 다수의 주파수 대역에서 작동되도록 하는 것이다. 이를 위해서, 2개의 접점상의 방사 표면에 3개 또는 4개의 접촉부가 형성되는, 안테나에 전력을 공급하는 특수한 방식이 사용된다.The process according to the invention essentially connects both partial regions, allowing the entire system to operate in multiple frequency bands. For this purpose, a special way of powering the antenna is used, in which three or four contacts are formed on the radiating surface on the two contacts.
본 발명에 따른 안테나의 목적에 맞는 그 밖의 형성은 종속항 및 본 발명에 따른 안테나의 실시예를 통해서 다음과 같이 설명된다.Other formations for the purpose of the antenna according to the invention are described as follows through the embodiments of the antenna according to the dependent claims and the invention.
본 발명은 도면에 도시된 실시예에 의하여 다음과 같이 보다 자세하게 설명된다.The invention is explained in more detail as follows by the embodiment shown in the drawings.
도 1 및 도 2에 도시된 실시예에서 도시된 2개의 부분 구조물(S1,S2)은 도선(L1)에 의하여 규정된 연결 장소(P1,P2)에서 서로 결합된다. 부분 구조물(S1)은 대체로 L자 모양으로 형성되어 있는 한편, 부분 구조물(S2)은 대체로 직사각형으로 형성된다.The two substructures S1 and S2 shown in the embodiment shown in FIGS. 1 and 2 are joined to each other at the connection sites P1 and P2 defined by the conductor L1. The partial structure S1 is formed in a generally L-shape while the partial structure S2 is formed in a generally rectangular shape.
부가적으로 또 다른 2개의 연결 장소(P3,P4)가 제 2 도선(L2)에 의하여 서로 결합된다.In addition, two other connection sites P3 and P4 are coupled to each other by the second conductive wire L2.
상기 도선(L1,L2)의 정해진 2개 장소에서 2개의 콘택(K1,K2)이 구현된다.Two contacts K1 and K2 are implemented at two predetermined locations of the conductive lines L1 and L2.
그러므로 안테나는 극이 2개인 접속콘택을 가진 2개의 병렬 회로 부분 영역으로 구성된다.The antenna therefore consists of two parallel circuit subregions with two pole contacts.
이 안테나는 2개의 상이한 표면 구조물 또는 패치(patch)로 구성된다. 여기서 L자 모양의 패치는 주로 GSM-대역에서 운용되며, 거의 직사각형의 패치는 주로 PCN-대역에서 운용된다. 그러므로 상기 양쪽 패치를 도선으로 결합함으로써, 전체 시스템이 2개의 또는 다수의 대역에서 작동될 수 있다.This antenna consists of two different surface structures or patches. The L-shaped patch is mainly operated in the GSM-band, and the almost rectangular patch is mainly operated in the PCN-band. Therefore, by combining both patches with wires, the entire system can be operated in two or multiple bands.
양쪽 안테나 패치(S1,S2)는 도선(L1,L2)에 의해서 서로 결합된다. 또한 도선(L1)은 짧고 넓은 금속 스트립 및 패치의 한 부분으로 형성될 수도 있다(도 2 참조).Both antenna patches S1 and S2 are coupled to each other by conducting wires L1 and L2. Conductor L1 may also be formed as part of a short, wide metal strip and patch (see FIG. 2).
연결 장소(P1,P2)는 통상적으로 양쪽 패치(S1,S2)의 마주보는 모서리에 위치한다. 패치(S1)상에 있는 연결 장소 (P4)와 (P1)의 간격 및 패치(S2)상에 있는 연결 장소 (P2)와 (P3)의 간격은 상당하게 안테나의 입력 임피던스를 결정한다.Connection sites P1 and P2 are typically located at opposite edges of both patches S1 and S2. The spacing between the connection sites P4 and P1 on the patch S1 and the spacing between the connection sites P2 and P3 on the patch S2 considerably determine the input impedance of the antenna.
콘택 (K1)과 (K2)는 특히 안테나의 입력 임피던스에 의해서 결정되며, 주로는 인쇄회로 기판의 레이아웃(layout)에 의해서 결정된다. 하나의 콘택은 인쇄회로 기판의 접지와 접속되며, 다른 하나의 콘택은 이동 무선기기 전자 송신기 또는 수신기의 입력과 접속된다.The contacts K1 and K2 are determined in particular by the input impedance of the antenna, mainly by the layout of the printed circuit board. One contact is connected to the ground of the printed circuit board, and the other contact is connected to the input of the mobile radio electronic transmitter or receiver.
이동 무선기기의 전자 장치에 의해서 임피던스(일반적으로 50 오옴)가 결정된다. 계산에 의거하여 연결 장소(P3,P4)의 위치가 선택됨으로써, 전자 장치 및 안테나의 임피던스가 복합적으로 서로 접속된다.The impedance (typically 50 ohms) is determined by the electronic device of the mobile radio. By selecting the positions of the connection sites P3 and P4 based on the calculation, the impedances of the electronic device and the antenna are connected to each other in combination.
도 3 내지 도 5는, 예컨대 이동 무선기기 내에 내장될 수 있는, 본 발명의 구체적인 실시예이다.3 to 5 are specific embodiments of the invention, which may be incorporated, for example, in a mobile radio.
