Description

위성방송 수신용 평면 안테나Flat antenna for satellite broadcasting

제1도는 본 발명의 구성을 보인 일부절개 사시도.1 is a partially cutaway perspective view showing the configuration of the present invention.

제2도는 入자형 평면 안테나의 동작 원리도.2 is an operating principle diagram of the plug-in planar antenna.

제3도는 다른 실시예로서 단층 공동으로 된 入자형 평면안테나의 동작 원리도.3 is another embodiment of the operation principle of the plug-in planar antenna of a single layer cavity.

본 발명은 위성방송을 수신하는데 사용하는 평면 안테나에 관한 것으로 더욱 상세히는 入자형 홈을 소요원판파의 방향에 따라서 우선 또는 좌선할 수 있도록 스파이랄형으로 알루미늄-폴리에치렌(A1-PE)원형 박판상에 배열하여 안테나 수신면 전체에서 일정한 특성을 얻을 수 있게 한 위성방송 수신용 평면안테나에 관한 것이다.The present invention relates to a planar antenna used to receive satellite broadcasts. More specifically, an aluminum-polyethylene (A1-PE) circular shape is formed in a spiral shape so as to prioritize or squeeze the groove according to the direction of the required wave. The present invention relates to a planar antenna for satellite broadcast reception, which is arranged on a thin plate so that a certain characteristic can be obtained over an entire antenna receiving surface.

일반적으로 사용되어 온 파라보라형 안테나는 용적이 크고, 무거우면 설치가 까다로운 결점이 있기 때문에 소비자가 직접 설치할 수 없는 결함이 있었다.Parabolic antennas, which have been used in general, have a drawback that cannot be installed by consumers because of their drawbacks.

본 발명은 이러한 점에 착안하여 훨씬 용적이 작고 가벼우면서도 설치가 간단하고 특히 작은 용적의 평면 안테나를 제공하면서도 파라보라형에 비해 고효율의 수신상태를 갖을 수 있게 한 것이다.The present invention has been made in view of this point, so that the volume is much smaller and lighter, and the installation is simpler, and in particular, it is possible to have a reception state of higher efficiency than parabolic type while providing a flat antenna of small volume.

이를 첨부된 도면 제1도 내지 제2도에 의해 상세히 설명하면,When described in detail with reference to the accompanying drawings 1 to 2,

제1도는 본 발명의 구성을 보인 일부절개 사시도이고 제2도는 入자형 평면 안테나의 동작원리도로서 알루미늄-폴리에치렌(A1-PE)박판(1)에 ＂入＂형 홈(2)를 스파이랄형으로 구성하된 본 홈(2)의 길이는 사용파장의 반이 되도록하여서 이것을 중심부근 근처에서 스파이랄형으로 90˚바뀔 때마다 먼저 위치에서 90˚회전하도록 나열하여 그때의 소자간 간격은 반파장에서 0.7내지 0.9파장 사이가 좋고 0.8파장일 때 가장 좋다.FIG. 1 is a partially cutaway perspective view showing the structure of the present invention, and FIG. 2 is a principle of operation of the plug-in flat antenna. The groove 2 is inserted into the aluminum-polyethylene (A1-PE) thin plate (1). The length of the groove 2, which is composed of an iral shape, should be half of the wavelength used, so that it is rotated by 90 ° from the position every time it changes 90 ° to the spiral shape near the central root. It is best when the wavelength is between 0.7 and 0.9 wavelengths and 0.8 wavelengths.

또한 스파이랄간 핏찌의 간격도 반파장에서 0.8파장 일때가 가장 좋은 것으로 나타났다.In addition, the interval between spiral pitches is best when the half-wave is 0.8 wavelength.

이와 같이 나열된 소자군은 주변쪽으로 갈수록 그 수가 많아짐에 따라서 주변쪽으로 갈수록 약해지는 본래의 원판특성을 보완하여서 면전체에 있어서 일양한 특성을 얻을 수 있도록 하여 고효율의 안테나를 얻을 수 있도록 한 것이다.As described above, the device groups listed are supplemented with the original disk characteristics, which become weaker toward the periphery, so that various characteristics can be obtained in the entire surface, thereby obtaining a highly efficient antenna.

또한 평면안테나(3)의 박판(1)상에 입사된 전자파 또는 복사되는 전자파는 증폭원과 각소자의 위치에 따라서 진행파형으로 결합을 스치로폴판(4)과 테프론 또는 폴리에치렌으로 된 유전체(5)가 알리미늄-폴리에치렌 박판(1)사이에서 공동을 형성하며 진행파에 대하여 원주부분이 먼저 진행이 되고 중심부분은 유전체(5)와 중심에서 원주까지의 거리에 따라서 나중에 원주방향으로 나오는 진행파에 의하여 진행원편파를 얻을 수 있게 된다.In addition, electromagnetic waves incident on the thin plate 1 of the planar antenna 3 or radiated electromagnetic waves are combined into a traveling wave in accordance with the position of the amplification source and each element, and a dielectric composed of the styropole plate 4 and Teflon or polyethylene ( 5) forms a cavity between the aluminum-polyethylene thin plates (1), and the circumferential portion proceeds first with respect to the traveling wave, and the center portion is later released in the circumferential direction according to the distance from the center to the circumference of the dielectric (5). The traveling wave can be obtained by the traveling wave.

이때 측면 금속하우징(6)에 의하여 전면공동에서 후면 공동으로 회전되면서 중앙에 위치한 알루미늄판(7)과 후면에 위치한 알루미늄판(8) 사이에서 TEM(Transeverse Electric Mode)파가 후면 공동 내에 발생된다.At this time, a TEM (Transeverse Electric Mode) wave is generated in the rear cavity between the aluminum plate 7 located at the center and the aluminum plate 8 located at the rear side while rotating from the front cavity to the rear cavity by the side metal housing 6.

또한 스치로폴판(9)(10)은 간격을 공진공동으로 구성하며 유전체 피막프로브(11)에서 공진공중선을 구성하며 인출 연결자(12)를 통하여 증폭단(도시되지 않음)과 연결된다.In addition, the sciropol plates 9 and 10 constitute resonant cavities at intervals, constitute a resonant air line in the dielectric film probe 11, and are connected to an amplifier stage (not shown) through the lead connector 12.

도면 중 미설명 부호 13,14,15는 입사파의 진행방향을 도시한 것으로 13은 각 소자로부터 입사되는 입사파를 중심부분과 주변부분에서 나타내고 있으며 14는 이들 진행파가 주변에서부터 먼저 회전하면서 피막프로부(11)에서 부호15와 같이 유기된 것을 인출연결자(12)로부터 출력을 얻을 수 있는 상태를 보인 것이다.In the drawings, reference numerals 13, 14, and 15 denote directions in which incident waves travel. 13 denotes incident waves incident from each element at the center and peripheral portions, and 14 indicates that the traveling waves rotate first from the periphery. It shows the state that the output is obtained from the withdrawal connector 12, which is separated as shown at 15 in the section (11).

또다른 실시예로는 반사판에 의해서 반사된 주변파가 중심부에서 동축프로부에 차례로 진행되어 인출연결자와 연결도출되는 상태를 보인 것으로 入자형 홈(2)을 통과한 전자파가 반사판(16)에 의해서 반사된 주변파는 중심부(17)에서 동축프로브의 선로인출 연결자(12)를 통하여 연결도출되고, 또는 도파관으로 유도함으로써 어떤 컨버터와도 연결하여 사용할 수 있는 것으로 공동이 한 개로서 본 발명과 동일한 효과를 얻을 수 있는 상태를 보일 수 있는 것이다.In another embodiment, the surrounding wave reflected by the reflecting plate progresses from the center to the coaxial pro part in order to be connected to the drawing connector. The electromagnetic wave passing through the recessed groove 2 is reflected by the reflecting plate 16. The reflected ambient wave is connected and drawn out through the line lead connector 12 of the coaxial probe at the central portion 17, or can be connected to any converter by inducing a waveguide. You can show what you can get.

이상과 같이 구성된 入자형 평면 안테나 다층 마이크로 스트립형 어레이 공중선에 비하여 공중선 소자와 결합인출 연결자에서 결합전송손실이 없게되고 안테나 수신면 전체에서 일양한 특성을 얻을 수 있는 것이다.Compared to the embedded flat antenna multi-layer microstrip array aerial structured as described above, there is no coupling transmission loss in the aerial element and the coupling lead-out connector, and various characteristics can be obtained in the entire antenna receiving surface.
