본 고안은 송수신기 입, 출력단과 송수신 안테나 사이에 있어서 각 송수신 주파수에 동조하여 그 대역만을 통과시키며 임피단스 정합을 이루면서 고유송수신 주파수의 여러개의 송수신 입출력을 한 개의 입, 출력으로 정합 결속시켜 한개의 송수신 안테나로 다중 송수신 입, 출력을 접속시킬 수 있는 다찬넬 송수신 안테나 정합기회로에 관한 것이다.The present invention tunes each transmit / receive frequency between the transceiver input / output stage and the transmit / receive antenna and passes only the band. The present invention relates to a multi-channel transmit / receive antenna matching circuit capable of connecting multiple transmit / receive inputs and outputs to an antenna.

본 고안은 터널이나 지하상가 등과 같은 지하 구축구조물내에 있어서 지표나 건축구조 자재의 전파흡수로 인하여 발생되는 방송전파의 부재 혹은 전계강도의 약화로 인한 라디오 방송의 청취곤란과 청취 불가능 상태 또는 산간벽지나 도서지방과 같이 방송국으로부터 원거리에 위치하여 전계 강도가 약화되어 라디오 방송의 청취가 곤란한 상대등을 해소시키기 위해 현재까지 막대한 비용을 들여 비경제적인 매 방송마다 방송국 단위로 지방 방송국이나 송신중계소를 시설 운영해 오고 있으나 이러한 중계장치에 있어서 방송국의 위치와 고유방송 주파수가 각기 다르다 할지라도 중계되어지는 수개의 지역방송을 한데묶어 한 대의 다찬넬 무선방송중계 장치로 동시The present invention is a difficult to hear and inaudible state of radio broadcasting due to the absence of broadcast waves or the weakening of electric field strength in underground construction structures such as tunnels and underground shopping centers. We are operating local broadcasting stations and transmission centers at the station level for every uneconomical broadcast at a very high cost to solve those who are difficult to listen to radio broadcasts due to weakened electric field strength because they are located far from the broadcasting stations like the islands. However, even though the position of the broadcasting station and the unique broadcasting frequency are different in these relay devices, several local broadcasts that are to be relayed are bundled together and simultaneously connected to a single Chanchanelle wireless broadcasting relay.

본 고안의 다찬넬 송수신 안테나 정합기는 이러한 여러 찬넬 송수신 입출력을 한 개의 송수신 안테나로 접속연결 시킬수 있는 여러 고유 주파수의 송수신 입출력을 하나의 송수신 입출력으로 다중화하는 효과가 있는 것이다.The Chanel transceiver antenna matching device of the present invention has the effect of multiplexing the transmission / reception inputs and outputs of various natural frequencies that can be connected to one channel transmission / reception input / output by one transmission / reception antenna.

개개의 고유방송 주파수의 송수신 입출력을 하나로 결속 정합시키기 위해서는 인접찬벨 주파수 혹은 고주파들을 포함한 다른 모든 불필요한 주파수들에 대해 상호 간섭을 억제할 수 있으며, 충분한 통과대역을 갖는 회로가 필요하다. 대역통과 필터는 이러한 조건에 적합한 회로로서 이를 첨부한 도면에 의해 상세히 설명하면 다음과 같다.In order to match the transmission / reception input / output of individual natural broadcasting frequencies into one, a circuit having sufficient passbands can be suppressed with mutual interference on all other unnecessary frequencies including adjacent channel frequencies or high frequencies. The bandpass filter is a circuit suitable for such a condition and will be described in detail with reference to the accompanying drawings.

본 고안은 대역통과 필터로 구성되어 있으며, 이 대역통과 필터를 설명하면, 제1도에 도시한 바와 같이 코일(L1), 콘덴사(C1)로 이루어진 저역통과 필터 부분과 코일(L2), 콘덴사(C2)로 이루어진 또 하나의 저역통과 필터 그리고 두개의 저역통과 필터를 고역통과만으로 결합시켜서 제3도에 도시한 통과대역폭을 결정하여 주는 콘덴사(C3)로 이루어져 있다.The subject innovation consists of a band-pass filter, this will be described the band pass filter, a coil as shown in Figure 1 (L 1), the low-pass filter portion and a coil consisting of a cone densa (C 1) (L 2 ), it consists of a cone densa (C 2) cone densa (C 3) to the by binding only by passing high-band to another low-pass filter and the two low-pass filter consisting of determining the pass band shown in FIG. 3 in.

제1도에 도시한 ZT는 다른 찬넬의 대역통과 필터의 출력임피단스의 합성 임피단스를 등가적으로 표시한 것이다.ZT shown in FIG. 1 is an equivalent representation of the composite impedance of the output impedance of the bandpass filter of another channel.

코일(L1L2), 콘덴사(C1C2C3)의 정수에 의해 결정되는 제4도에 도시한 동조 특성의 6개의 대역통과 필터를 제2도에 도시한 상세회로와 같이 접속하여 6개의 고유 주파수의 송수신 입출력을 각기 임피단스 정합을 이루며, 한개의 송수산 안테나에 연결시킬 수 있게 한개의 입출력으로 정합결속하는 회로를 구성했다.The six bandpass filters of the tuning characteristics shown in FIG. 4 determined by the constants of the coils L 1 L 2 and condensate C 1 C 2 C 3 are connected as in the detailed circuit shown in FIG. Therefore, the circuits for transmitting / receiving inputs and outputs of six natural frequencies each have an impedance matching, and a circuit is matched with one input / output for connection to one antenna.

인접찬넬 억압비와 송수신 입출력의 제2고조파 스프리이스 억압비를 개선하기 위해서 제5도에 도시한 바와 같이 대역통과 필터를 다단 종속 접속할 수도 있으며, 주파수 동조점의 미세조정을 위해 콘덴사(C1C2C3)를 반고정 가변용량 트리머로 대치하거나 병렬 추가할 수도 있다. 대역통과 필터의 입, 출력 임피단스는 코일(L1)의 정수로 결정되고, 입, 출력 임피단스는 코일(L2)의 정수에 의해 결정된다. 따라서 코일(L1)의 정수는 정합기의 입, 출력 임피단스로 되며, 어떠한 입, 출력 임피단스의 비라도 간단히 정합시킬 수 있다.In order to improve the adjacent channel suppression ratio and the second harmonic splice suppression ratio of the transmission / reception input / output, a bandpass filter may be cascaded as shown in FIG. 5, and condensate (C) is used for fine tuning of the frequency tuning point. 1 C 2 C 3 ) can be replaced by a semi-fixed variable-capacitance trimmer or added in parallel. The input and output impedance of the bandpass filter is determined by the constant of the coil L 1 , and the input and output impedance are determined by the constant of the coil L 2 . Accordingly, the constant of the coil L 1 becomes the input and output impedance of the matching unit, and any ratio of input and output impedances can be easily matched.

이상과 같이 본 고안은 한개의 송수신 안테나를 다중 찬넬화하여 모든 해당 찬넬 입, 출력에 임피단스 정합이 이루어지며, 충분한 통과대역 특성을 갖고 인접찬넬 또는 불요 고조파 복사를 억압시킬 수가 있어 실용적으로 효과가 큰 고안이라 하겠다.As described above, the present invention implements an impedance matching on all corresponding channel inputs and outputs by multiplexing one transmit / receive antenna, and has sufficient passband characteristics and can suppress adjacent channels or unwanted harmonic radiation. It is a great design.
