본 발명은, 위성 방송 수신용 파라볼라 안테나에 관한 것으로, 특히 VSWR을 조정하기 위한 1차 방사기의 구조에 관한 것이다.The present invention relates to a parabolic antenna for satellite broadcast reception, and more particularly to the structure of a primary radiator for adjusting VSWR.

파라볼라 안테나에 의한 위성 방송의 수신은, 도3에 도시된 바와 같이, 안테나부(71)에서 반사된 약 12GHz대의 신호 S가, 1차 방사기(72)의 개구부(73)에 집약되도록 되어 있다. 그리고, 1차 방사기(72)를 통과한 신호는, LNB(Low Noise Block down-converter)(74)에 의해 12GHz대에서 1GHz대로 주파수 변환되고, 이 주파수 변환된 신호가 케이블(75)을 통해 옥내 수신기(BS(또는 CS) 튜너, 또는 내장 TV(또는 VTR))(76)에 입력되도록 되어 있다.As shown in Fig. 3, the satellite broadcast by the parabola antenna is such that the signal S reflected by the
여기서, 파라볼라 안테나용의 1차 방사기(72)는, 도4에 도시된 구조로 되어 있다.Here, the
즉, 혼(horn) 안테나 본체(81)는 원통 형상으로 형성되어 있고, 부채 모양(扇狀)으로 퍼진 선단(先端) 개구부(82)에 방수 커버(91)가 압입(壓入)에 의해 끼워져 있다. 이 방수 커버(91)는, 외부로부터 1차 방사기의 혼 안테나 본체(81) 내부로 비 등의 수분이 들어가지 않도록 하기 위한 것이다. 그 때문에, 혼 안테나 본체(81)의 단부 개구부(82)와 방수 커버(91) 사이에는, 지수(止水)용의 O링(100)을 삽입함으로써, 방수 기능을 유지하고 있다.That is, the horn antenna
이 방수 커버(91)는, 플라스틱 등의 수지로 형성되어 있기 때문에, 공기에 대해 비교적 높은 유전율을 갖고 있다. 그 때문에, 방수 커버(91)의 형상이, 1차 방사기를 포함한 입력 VSWR에 크게 영향을 주게 된다.Since the
예컨대, 일본 국내에서 위성 방송 BS(전송 주파수 11.7∼12.OGHz : 대역폭 300MHz)를 수신할 때, 이 방수 커버(91)에 의해 VSWR이 영향을 받는다.For example, when receiving a satellite broadcast BS (transmission frequency 11.7 to 12 GHz: bandwidth 300 MHz) in Japan, the VSWR is affected by this
그 때문에, 이 방수 커버(91)의 내벽면(92)에는, VSWR을 억제하기 위한 원통 형상의 돌기부(92)가 형성되어 있다. 이 돌기부(92)는 혼 안테나 본체(81)의 단부 개구부(82)측으로 돌출하여 형성되어 있고, 또한 혼 안테나 본체(81)의 중심축 L1과 동심축상으로 배치되어 있다. 이와 같이 돌기부(92)의 내부를 공동(空洞)으로 함으로써, 입력 VSWR을 억제하고 있다.Therefore, the
그런데, 최근 일본 국내에서는, 방송 위성(BS)과 동일한 동경 110°의 위치에 새로이 CS 디지털 방송용의 위성(전송 주파수 12.2GHz∼12.75GHz : 대역폭 1050MHz)이 쏘아올려져 서비스를 개시하고 있다. 그 때문에, 1개의 파라볼라 안테나에서 BS 및 디지털 CS의 양방을 수신하기 위해서는, 입력 주파수 11.7∼ 12.75GHz(대역폭 1050MHz)에 대해 입력 VSWR이 적은 양호한 1차 방사기가 필요하게 되고 있다.In recent years, however, in Japan, a satellite for CS digital broadcasting (transmission frequency 12.2 GHz to 12.75 GHz: bandwidth 1050 MHz) has been newly launched at the same 110-degree eastward position as the broadcast satellite BS to start a service. Therefore, in order to receive both BS and digital CS in one parabola antenna, a good primary radiator with a small input VSWR is required for an input frequency of 11.7 to 12.75 GHz (bandwidth 1050 MHz).
그렇지만, 상기한 종래의 파라볼라 안테나용 1차 방사기(72)에서는, 대역폭이 500∼800MHz 정도의 주파수에 대해서는 VSWR을 양호하게 억제할 수 있지만, 1050MHz의 대역폭까지 VSWR을 양호하게 억제하는 것이 어렵다고 하는 문제가 있었다. 그리고, VSWR을 억제하는 양호한 특성이 얻어지지 않는 경우에는, 안테나 토탈의 교차 편파 특성을 23dB 이상 얻는 것이 어렵다고 하는 문제도 있었다.However, in the above-described conventional parabolic antenna
본 발명은 관계되는 문제점을 해결하기 위해 창안된 것으로, 그 목적은, 1050MHz의 대역폭까지 VSWR을 양호하게 억제할 수 있는 구조의 파라볼라 안테나용 1차 방사기를 제공하는 것에 있다.The present invention was devised to solve the related problems, and an object thereof is to provide a primary radiator for a parabolic antenna having a structure capable of suppressing VSWR to a bandwidth of 1050 MHz.
상기 목적을 달성하기 위해, 본 발명의 파라볼라 안테나용 1차 방사기는, 혼 안테나 본체의 단부 개구부에 방수 커버가 제공되고, 이 방수 커버의 내벽면에, 상기 단부 개구부로 향하고, 또한 상기 혼 안테나 본체의 중심축과 동심축상으로 배치된 유전체로 이루어지는 원통 형상의 돌기부가 형성된 파라볼라 안테나용 1차 방 사기에 있어서, 상기 돌기부의 개구 선단부에 고리 모양(環狀)의 단차부가 형성되어 있다. 이와 같이, 돌기부의 개구 선단부에 고리 모양의 단차부를 형성함으로써, 외측의 높은 단차 돌기가 낮은 주파수의 VSWR을 억제하고, 내측의 낮은 단차 돌기가 높은 주파수의 VSWR을 억제할 수 있어, 1050MHz의 넓은 대역폭에 걸쳐, 입력 VSWR을 효과적으로 억제하는 것이 가능하게 된다. 또한, 후단으로 이어지는 블록의 교차 편파 특성을 열화시키지 않고, 양호한 교차 편파 특성(23dB 이상)을 실현할 수 있다.In order to achieve the above object, the primary radiator for a parabolic antenna of the present invention is provided with a waterproof cover at an end opening of a horn antenna body, and faces an inner wall surface of the waterproof cover toward the end opening, and furthermore, In the primary barrier for a parabola antenna having a cylindrical projection formed of a dielectric arranged concentrically with the central axis of the antenna, an annular step is formed at the opening end of the projection. In this way, by forming an annular stepped portion at the opening end of the protruding portion, the outer high stepped projection can suppress a low frequency VSWR and the inner low stepped projection can suppress a high frequency VSWR, thereby providing a wide bandwidth of 1050 MHz. It is possible to effectively suppress the input VSWR. Further, a good cross polarization characteristic (23 dB or more) can be realized without degrading the cross polarization characteristic of the block leading to the next stage.
또한, 본 발명의 파라볼라 안테나용 1차 방사기는, 혼 안테나 본체의 단부 개구부에 방수 커버가 제공된 파라볼라용 1차 방사기에 있어서, 상기 방수 커버의 내벽면에, 상기 단부 개구부로 향하고, 또한 상기 혼 안테나 본체의 중심축과 동심축상으로 배치된 유전체로 이루어지는 원통 형상의 돌기부가 복수 제공되는 동시에, 외측의 돌기부에 대해 내측의 돌기부의 높이가 낮게 형성되어 있다. 이에 의해, 외측의 높은 돌기부가 낮은 주파수의 VSWR을 억제하고, 내측의 낮은 돌기부가 높은 주파수의 VSWR을 억제할 수 있어, 1050MHz의 넓은 대역폭에 걸쳐, 입력 VSWR을 효과적으로 억제하는 것이 가능하게 된다. 또한, 후단으로 이어지는 블록의 교차 편파 특성을 열화시키지 않고, 양호한 교차 편파 특성(23dB 이상)을 실현할 수 있다.Further, the primary radiator for a parabolic antenna of the present invention is a parabolic primary radiator provided with a waterproof cover at an end opening of a horn antenna main body, which is directed toward the end opening of the inner wall of the waterproof cover, and further comprises the horn antenna. A plurality of cylindrical protrusions made of a dielectric arranged concentrically with the central axis of the main body are provided, and the height of the inner protrusions is lower than the outer protrusions. As a result, the outer high protrusions can suppress the low frequency VSWR, and the inner low protrusions can suppress the high frequency VSWR, so that the input VSWR can be effectively suppressed over a wide bandwidth of 1050 MHz. Further, a good cross polarization characteristic (23 dB or more) can be realized without degrading the cross polarization characteristic of the block leading to the next stage.
