일반적으로 자동차 등에 사용되는 안테나로서는 휩안테나(Whip Antenna)가 주로 사용되어져 왔다. 이와같은 휩안테나는 자동차의 주행시 바람에 의한 소음이 심하고 파손되는 경우가 많아서 수명이 단축되는 문제점이 있다. 뿐만아니라, 장기적으로 사용할 때 외부로 돌출되는 안테나폴 사이에 이물질이 끼어 수신감도가 저하됨은 물론 고장이 발생되는 문제점이 있었다.Generally, as an antenna used in automobiles, a whip antenna has been mainly used. Such whip antennas have a problem in that the life of the vehicle is shortened because the noise caused by the wind during driving of the vehicle is severe and often broken. In addition, there is a problem that the reception sensitivity is lowered as well as a failure occurs between the antenna pole protruding to the outside when used for a long time.

최근에는 차의 뒷유리창에 열선과 함께 형성한 유리안테나가 이용되고 있다. 그러나, 이러한 유리안테나는 차의 외형에 따른 설계가 어렵고 비용이 많이 들뿐만 아니라 차의 주행방향에 따른 지향성 수신특성이 떨어지는 결점이 있었다.Recently, a glass antenna formed with a hot wire on the rear window of a car has been used. However, such a glass antenna is difficult to design according to the appearance of the car and is expensive, and also has a drawback in that the directional reception characteristic according to the driving direction of the car is inferior.

따라서, 본 발명의 목적은 위와같은 종래기술의 제문제점들을 해소할 수 있는 박형안테나를 제공하는데 있다.Accordingly, an object of the present invention is to provide a thin antenna that can solve the above problems of the prior art.

본 발명의 다른 목적은 차랑의 경랑화를 달성할 수 있는 소형경량의 박형안테나를 제공하는데 있다.It is another object of the present invention to provide a compact and lightweight thin antenna that can achieve the tilting of the car.

본 발명의 또 다른 목적은 파우워안테나의 경우에 발생하는 작동중 노이즈가 없는 안테나를 제공하는데 있다.Another object of the present invention is to provide an antenna free of noise during operation occurring in the case of a power antenna.

본 발명의 또 다른 목적은 안테나가 작동하지 않을 때 암전류에 의한 배터리의 로스(Loss)가 없고 유지보수가 용이한 안테나를 제공하는데 있다.Still another object of the present invention is to provide an antenna that is easy to maintain and has no loss of battery due to dark current when the antenna is not operated.

위와같은 목적들을 달성하기 위한 본 발명에 따른 자동차용 박형안테나의 특징은Features of the thin antenna for automobiles according to the present invention for achieving the above objects are

안테나에 있어서, 소정의 길이와 폭을 갖고 절연물질로 구성된 얇은박판 ; 및 상기 박판의 앞·뒷면을 통해 길이방향으로 헤리칼형태로 형성된 도전체를 포함하는 박형안테나에 있다.An antenna comprising: a thin sheet having a predetermined length and width and made of an insulating material; And a conductor formed in a helical shape in the longitudinal direction through the front and rear surfaces of the thin plate.

상기 박판은 길이방향을 따라 양가장자리 부근에 다수의 구멍들이 형성되고, 상기 도전체는 다수의 구멍들을 전도성물질로 코팅하고 상기 박판의 양면상에 대략 사선으로 마주보는 구멍들을 도전체로 연결하되 일측단부로부터 길이방향으로 타측단부까지 하나의 도전로가 형성되도록 연결되는 것을 특징으로 한다.The thin plate is formed with a plurality of holes in the vicinity of both edges along the longitudinal direction, the conductor is a plurality of holes coated with a conductive material and connect the holes facing approximately diagonally on both sides of the sheet with a conductor, one end Characterized in that it is connected so that one conductive path is formed from the other end in the longitudinal direction.

또한, 상기 도전체는 임피던스정합을 위하여 중간지점에서 서로 반대방향으로 감겨진 형태를 특징으로 한다.In addition, the conductor is characterized in that the shape wound in opposite directions from the intermediate point for the impedance matching.

이하에서, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다. 제1도는 본 발명의 바람직한 실시예에 따른 박형안테나의 사시도이고, 제 2도는 제1도의 선 Ⅰ-Ⅰ에 따른 단면도, 제 3도는 제 1도의 A부분에 대한 전면부의 확대사시도, 그리고 제 4도는 제 1도의 A부분에 대한 배면부의 확대사시도이다. 도시한 바와같이, 본 발명의 박형안테나는 소정의 길이와 폭을 갖고 절연물질로 구성된 얇은 박판(10)을 구비하고 있다. 이 박판(10)의 앞·뒤면을 통해 길이방향을 따라 헤리칼형태의 도전체(20)가 형성되어 있다. 좀 더 구체적으로 설명하면, 박판(10)은 길이 방향을 따라 양가장자리 부근에 다수의 구멍들(12)이 형성되고, 이 구멍들은 전도성물질로 코팅되어 있다. 그리고, 박판(10)의 양면 즉, 전면과 배면에는 각각 대략 사선으로 마주보는 구멍들을 도전체(20)로 연결한다. 이때, 도전체(20)는 박판(10)의 일측단부로부터 길이방향으로 타측단부까지 하나의 도전로가 형성되도록 구멍들(12)사이를 연결한다. 따라서, 하나의 도전로를 형성하는 도전체(20)는 박판의 전·배면을 교호로 도금된 구멍들(12)을 통해 연결되므로 헤리칼형태를 취하고 있다. 또한, 도전체(20)는 도전체(20)의 전체길이 중 대략 중간지점에서 임피던스정합을 위하여 서로 반대방향으로 감겨진 형태를 취하고 있다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. 1 is a perspective view of a thin antenna according to a preferred embodiment of the present invention, FIG. 2 is a sectional view taken along the line I-I of FIG. 1, FIG. 3 is an enlarged perspective view of the front portion of part A of FIG. 1, and FIG. An enlarged perspective view of the back portion of part A of FIG. As shown, the thin antenna of the present invention has a thin thin plate 10 made of an insulating material having a predetermined length and width. A helical conductor 20 in the longitudinal direction is formed through the front and rear surfaces of the thin plate 10. In more detail, the thin plate 10 has a plurality of holes 12 formed near both edges along the length direction, and the holes are coated with a conductive material. In addition, both sides of the thin plate 10, that is, the front and the rear, respectively, connect the holes facing each other with diagonal lines with the conductors 20. At this time, the conductor 20 connects the holes 12 so that one conductive path is formed from one end of the thin plate 10 to the other end in the longitudinal direction. Therefore, the conductor 20 forming one conductive path has a helical shape since the front and rear surfaces of the thin plate are connected through the alternately plated holes 12. In addition, the conductors 20 are wound in opposite directions for impedance matching at approximately midpoints of the entire length of the conductors 20.

위와같은 본 발명의 박형안테나를 제조하기 위해서는 에폭시 양면기판 또는 합성수지 양면에 알루미늄이나 동 등의 도체가 입혀져 있는 필름을 사용하여 도체양면에 코일형태의 패턴을 부식시켜 형성하고, 그 패턴의 가장자리에 구멍을 뚫어 도금처리하면 양면의 도체패턴이 결합하여 헤리칼형태를 형성할 수 있다.In order to manufacture the thin antenna of the present invention as described above, by using a film coated with a conductor such as aluminum or copper on both sides of an epoxy double-sided substrate or a synthetic resin, a coil-like pattern is formed on both sides of the conductor, and a hole is formed at the edge of the pattern. Through the plating process, the conductive patterns on both sides can be combined to form a helical shape.

또 다른 제조방법은 도체가 입혀져 있지 않은 합성수지에 사전에 설계된 간격만큼씩 다수의 구멍들을 형성하고 양면에 은과같은 도전성 잉크를 사용하여 인쇄하므로써 안테나패턴을 형성할 수도 있다.Another manufacturing method may form an antenna pattern by forming a plurality of holes in a synthetic resin that is not coated with conductor at predetermined intervals and printing using conductive ink such as silver on both sides.

한편, 박판(10)의 폭은 대략 3∼20㎜, 길이는 10∼300㎜인 것이 본 발명의 안테나를 위해 바람직하다. 또한, 구멍들(12)사이의 간격은 약 1∼10㎜인 것이 바람직하다. 미설명한 부호30은 안테나의 도전로를 장착물에 연결하기 위한 연결선이다.On the other hand, it is preferable for the antenna of the present invention that the width of the thin plate 10 is approximately 3 to 20 mm and the length is 10 to 300 mm. In addition, the spacing between the holes 12 is preferably about 1 to 10 mm. Unexplained reference numeral 30 is a connecting line for connecting the conductive path of the antenna to the mounting.

제 5도는 본 발명의 다른실시예에 따른 박형안테나의 사시도이다. 이 실시예는 제 1도의 실시예와 동일한 구성을 갖고 있으나, 제 1도의 연결선(30)대신에 도전체(20)를 안테나의 일측단부에 더 연장한 구성을 하고 있다. 또한, 연장된 도전체(20)의 연장단부에 신호를 증폭하는 증폭기(40)를 일체로 결합한 구성을 갖는 점이 상이하다.5 is a perspective view of a thin antenna according to another embodiment of the present invention. This embodiment has the same configuration as the embodiment of FIG. 1, but has a configuration in which the conductor 20 is further extended to one end of the antenna instead of the connecting line 30 of FIG. In addition, there is a difference in having a configuration in which the amplifier 40 for amplifying a signal is integrally coupled to the extended end of the extended conductor 20.

제 6도는 종래의 휩안테나와 본 발명의 박형안테나를 비교한 방송신호주파수대역의 신호이득 비교그래프이다. 도면에서, A는 본 발명의 안테나에 대한 수신신호 이득을 나타내는 그래프이고, B는 종래의 휩안테나에 대한 이득을 나타내는 그래프이다. 도면으로부터 알 수 있는바와 같이, 본 발명에 따른 안테나의 이득이 보다 향상된다는 것을 알 수 있다.6 is a signal gain comparison graph of a broadcast signal frequency band comparing a conventional whip antenna and a thin antenna of the present invention. In the figure, A is a graph showing the received signal gain for the antenna of the present invention, B is a graph showing the gain for the conventional whip antenna. As can be seen from the figure, it can be seen that the gain of the antenna according to the present invention is further improved.

이상에서 상세히 설명한 바와같이, 본 발명에 따른 박형안테나는 신호이득이 개선됨은 물론 소형경량화를 달성할 수 있고, 사용이 편리하며, 유지보수가 용이하는등 여러 가지의 장점을 제공한다.As described in detail above, the thin antenna according to the present invention provides various advantages, such as improved signal gain, small size and light weight, ease of use, and easy maintenance.
