본 발명은 쌍봉특성을 가지는 바란스 안테나에 관한 것으로, 특히 두개의 주파수 대역을 송수신할 수 있게 하는 것으로 지상파 디지털 방송 수신기기, 휴대폰, 무선랜 등에 적합한 안테나를 제공하고자 하는 것이다.The present invention relates to a balanced antenna having a bimodal characteristic, and in particular, to provide an antenna suitable for terrestrial digital broadcast receivers, cellular phones, wireless LANs, and the like, capable of transmitting and receiving two frequency bands.

일반적으로, 지상파 디지털 방송수신용 안테나는 하나의 채널(예컨대 12번 채널)을 사용하고 있는데, 하나의 안테나로서 다른 채널(예컨대 8번 채널)을 사용할 경우 안테나가 가지는 주파수 대여을 벗어나게 되므로 수신감도가 불량한 문제점이 지적되고 있다.In general, an antenna for terrestrial digital broadcasting reception uses one channel (for example, channel 12). When using another channel (for example, channel 8) as one antenna, the reception sensitivity is poor because the antenna is out of the frequency rental. The problem is pointed out.

또한, 휴대폰에 내장되는 안테나인 경우에는 하나의 안테나로 송수신이 가능하나, 단봉특성만을 가지고 있어 정재파비(SWR) 특성이 저하되어 수신감도가 불량하고 송신 복사율이 크게 저하되는 문제점이 있다. 특히, 휴대폰을 사용함에 있어서 사용자의 얼굴에 휴대폰을 갖다 대었을때 발생되는 페이스 이펙트(face effect) 및 손에 쥐었을때 발생되는 핸드 이펙트(Hand effect)로 인해 주파수가 튜닝되어 주파수 대역을 벗어나 송수신 감도가 저하되고, 또한 이와같이 주파수가 튜닝된다는 것은 휴대폰이 사람의 인체에 영향을 받는 것이어서 휴대폰에서 발생되는 전자파로 인해 인체에 악영향을 미치는 문제점이 지적된다.In addition, in the case of an antenna embedded in a mobile phone, it is possible to transmit and receive with one antenna. However, since the antenna has only a single-ended characteristic, standing wave ratio (SWR) characteristics are deteriorated, so that reception sensitivity is poor and transmission emissivity is greatly reduced. In particular, when using a mobile phone, the frequency is tuned due to the face effect generated when the mobile phone is placed on the user's face and the hand effect generated when the mobile phone is held in the hand. It is pointed out that the sensitivity is lowered and the frequency is tuned in such a way that the mobile phone is affected by the human body and thus adversely affects the human body due to electromagnetic waves generated from the mobile phone.

본 발명은 송수신 감도가 양호하고 전자파의 감소를 가져오게 하는 쌍봉특성을 가지는 안테나를 제공함을 기술적 과제로 삼는다.The present invention is to provide an antenna having a bimodal characteristic that has a good transmission and reception sensitivity and a reduction of electromagnetic waves.

본 발명은 베이스 몰딩부 상, 하에 안테나를 균형적으로 설치하되, 상기 안테나와 안테나 중심 일측에 로딩 코일을 접속하고, 베이스 몰딩부 타측 상단에 인덕턴스 조정용 조절부를 나사 결합한 다음, 상기 로딩코일 일측에 일정간극을 두고 픽업코일 및 트리머 콘덴서로 이루어진 안테나 수신 픽업부를 설치하여 구성함을 특징으로 한다. According to the present invention, the antenna is installed on the base molding unit in a balanced manner, and the loading coil is connected to one side of the antenna and the center of the antenna, and the coupling part of the inductance adjustment is connected to the upper end of the base molding unit, and then the one side of the loading coil is fixed. Characterized in that the antenna receiving pickup unit consisting of a pickup coil and a trimmer capacitor with a gap therebetween.

도 1은 지상파 디지털 방송 수신용 안테나를 실시예로 하여 보인 안테나 구성도이다.1 is an antenna configuration diagram illustrating an antenna for receiving terrestrial digital broadcasting in an embodiment.

쌍봉 특성 곡선을 갖는 바란스 안테나에 있어서, 베이스 몰딩부(10) 상, 하에 안테나(11)(11A)를 배치하여 안테나(11)와 안테나(11A) 사이의 중심 일측에 로딩 코일(20)을 연결하고, 상기 베이스 몰딩부(10) 타측 상단에 인덕턴스 조정용 조절부(30)를 나사결합한 다음, 상기 로딩코일(20) 일측에 일정간극(d)을 두고 상호병렬로 연결되는 픽업코일(41) 및 트리머 콘덴서(42)로 이루어진 안테나 수신 픽업부(40)를 설치하여 구성한다. 상기 베이스 몰딩부(10)의 타측에는 자석 또는 흡착구(50)를 고정시켜 차량 내부의 금속 또는 유리 표면에 본 발명의 안테나가 부착될 수 있게 한다. 상기에 있어 트리머 콘덴서(42)는 후술하는 본 발명의 쌍봉특성에 있어 전체적인 튜닝점을 셋팅하는 기능을 한다. In the balanced antenna having a bimodal characteristic curve, the antennas 11 and 11A are disposed above and below the base molding part 10 to connect the loading coil 20 to one side of the center between the antenna 11 and the antenna 11A. And, the screw coupling the inductance adjustment unit 30 on the other end of the base molding portion 10, the pick-up coil 41 is connected in parallel with a predetermined gap (d) on one side of the loading coil 20 and The antenna reception pick-up part 40 which consists of the trimmer capacitor 42 is provided and comprised. The other side of the base molding part 10 is fixed to the magnet or the suction port 50 so that the antenna of the present invention can be attached to the metal or glass surface inside the vehicle. In the above, the trimmer capacitor 42 functions to set the overall tuning point in the bimodal characteristic of the present invention described later.

상기 실시예의 구성은 지상파 디지털 방송 수신용 안테나에 해당되는 설명이나, 상기 구성의 안테나는 소형화하여 휴대폰에 상기 베이스몰딩부(10) 및 안테나(11A)를 내장 시키고 안테나(11)는 휴대폰 외부로 돌출시켜 사용할 수 있다. The configuration of the embodiment is a description corresponding to an antenna for receiving terrestrial digital broadcasting, but the antenna of the configuration is miniaturized so that the base molding unit 10 and the antenna 11A are embedded in the mobile phone, and the antenna 11 protrudes out of the mobile phone. Can be used.

이와같은 구성의 본원 발명은 로딩코일(20)에 예컨대 수신된 주파수가 200㎒일 경우 간극(d)을 가진 상태에서 픽업코일(41)이 근접되면 픽업 코일(41)과 트리머 콘덴서(42)와의 공진 및 픽업코일(41) 자체의 비철금속 성분으로 인해 로딩코일(20)의 인덕턴스 값이 변하여 주파수가 높아지게 되므로 로딩코일(20)에 수신된 주파수(예:200㎒)는 그대로 유지되면서 픽업 코일(41) 근접에 따른 공진에 의해 또 다른 높은 주파수(예:210㎒)가 픽업코일(41)에 픽업되어 두개의 주파수가 튜너측으로 출력되므로 쌍봉특성을 가지는 안테나를 얻게 되는 것이다. According to the present invention having the configuration described above, when the pickup coil 41 is close to the loading coil 20 with a clearance d when the received frequency is 200 MHz, the pickup coil 41 and the trimmer condenser 42 Since the inductance value of the loading coil 20 is changed due to the resonance and the non-ferrous metal component of the pickup coil 41 itself, the frequency is increased. Another high frequency (eg 210 MHz) is picked up by the pickup coil 41 by the resonance due to the proximity, and two frequencies are output to the tuner side, thereby obtaining an antenna having a bimodal characteristic.

즉, 도2에 도시한 안테나 네트워크 분석에 의해 얻어진 정재파비(SWR)값을 나타낸 바와같이 두개의 튜닝점을 가지는 쌍봉특성 그래프가 얻어짐을 알 수 있다. 따라서, 기존에 12번 채널 이외에 8번 채널도 수신할 수 있어 지상파 디지털 방송용 채널전부를 수용할 수 있게 되는 것이다. In other words, it can be seen that a bimodal characteristic graph having two tuning points is obtained as shown in the standing wave ratio (SWR) value obtained by the antenna network analysis shown in FIG. Therefore, in addition to the existing channel 12, the channel 8 can also be received to accommodate all the terrestrial digital broadcasting channel.

특히, 본 발명은 두개의 튜닝점의 간격을 조절하므로써 대역조절이 가능하다. 즉, 로딩코일(20)과 픽업코일(41) 사이의 간극(d)을 인덕턴스 조정용 조절부(30)로 조절함으로써 로딩코일(20)의 인덕턴스 용량이 가변되어 도 2와 같은 쌍봉특성을 가지게 되면서 두개의 대역조절이 가능하게 된다.In particular, the present invention enables band adjustment by adjusting the interval between two tuning points. That is, the inductance capacity of the loading coil 20 is varied by adjusting the gap d between the loading coil 20 and the pickup coil 41 by the inductance adjusting unit 30 to have a double-rod characteristic as shown in FIG. 2. Two band adjustments are possible.

한편, 본 발명은 상술한 바와 같이, 기존과 달리 로딩코일(20)가 픽업코일(41) 사이에 간극(d)을 두고 절연상태로 유지하는 절연된 바란스(균형) 안테나가 되므로 도 3의 안테나 주파수 영역의 임피던스 측정 그래프와 같이 임피던스가 안정되어 주파수 안정도가 향상되게 되고, 특히 페이스 이펙트 또는 핸드 이펙트가 상기 간극(d)에 의한 절연으로 인해 없으므로 휴대폰에 본 발명을 내장시켜 사용할 경우 주파수가 튜닝되는 것을 방지하게 되므로 송수신 감소 향상은 물론 전자파에 의한 인체의 악영향을 배제할 수 있게된다. On the other hand, the present invention, as described above, because the loading coil 20 is an insulated balance (balance) antenna to be maintained in an insulating state with a gap (d) between the pickup coil 41, the antenna of Figure 3 Impedance is stabilized as shown in the impedance measurement graph in the frequency domain, thereby improving frequency stability. In particular, since the face effect or the hand effect is due to the insulation by the gap d, the frequency is tuned when the present invention is embedded in a mobile phone. It is possible to prevent the reduction of transmission and reception, as well as to eliminate the adverse effects of the human body by electromagnetic waves.

본 발명은 두개의 튜닝점을 가지는 쌍봉특성의 절연된 바란스 안테나를 제공하게 되므로 송수신 감도 향상은 물론 전자파로부터 인체를 보호할 수 있는 효과를 가진다. Since the present invention provides an insulated balanced antenna having a bimodal characteristic having two tuning points, it has an effect of improving transmission and reception sensitivity as well as protecting a human body from electromagnetic waves.
