Abstract

본 고안은 대공망 레이더용 안테나, 이동 위성방송 수신용 반사경 안테나 등과 같은 수평 방향으로의 넓은 빔폭과 안테나의 높이를 최소화하는 요구에 부합되는 반사경 안테나에 적용 가능한 급전용 피드혼이다. The present invention is a feed horn that is applicable to a reflector antenna that meets the requirements of minimizing the height of the antenna and the wide beam width in the horizontal direction, such as an antenna for a radar antenna and a reflector antenna for receiving mobile satellite broadcasting.

본 고안의 주된 목적은 기존의 피드혼의 개구면(1)에 간단한 구조물(3)을 설치함으로써 수평방향 빔폭을 증가시켜 직사각형 형태의 반사경(5)의 피드혼으로 사용할 수 있게 하는 것이다. The main object of the present invention is to increase the horizontal beam width by providing a simple structure 3 on the opening surface 1 of the conventional feed horn so that it can be used as a feed horn of the reflector 5 of the rectangular shape.

기존의 피드혼(1)은 수평방향과 수직방향으로 비슷한 빔폭을 가지며 원형 반사경(4)의 급전에 적합하다. 이동 위성 수신용 반사경 안테나의 경우에서처럼 반사경 안테나의 높이를 줄이기 위해 원형 반사경의 위와 아래를 절단한 직사각형 형태의 반사경(5)이 사용된다. 이 경우 도 2와 같은 비대칭 빔폭을 가지는 급전용 피드혼이 요구된다. 이를 구현하기 위한 구성은 기존에 개발된 피드혼 안테나의 개구면(1)에 칸막이 구조(3)를 더하여 칸막이 사이의 간격(2) 조절에 의해 수평방향의 빔폭을 결정지을 수 있다.The conventional feed horn 1 has a similar beam width in the horizontal and vertical directions and is suitable for feeding the circular reflector 4. As in the case of the reflector antenna for mobile satellite reception, a reflector 5 having a rectangular shape cut above and below the circular reflector is used to reduce the height of the reflector antenna. In this case, a feed horn having asymmetric beamwidth as shown in FIG. 2 is required. In order to realize this, the partition structure 3 may be added to the opening surface 1 of the previously developed feed horn antenna to determine the beam width in the horizontal direction by adjusting the spacing 2 between the partitions.

본 고안은 기존의 대칭형 빔폭을 갖는 피드혼의 개구면(1)에 칸막이 구조물(3)을 더함으로써 비대칭형 빔폭을 구현한 것으로 수평 방향으로의 넓은 빔폭 구현과 반사경의 높이 최소화에 적용할 수 있는 피드혼이다.The present invention implements an asymmetric beam width by adding a partition structure 3 to the opening face 1 of a feed horn having a conventional symmetric beam width. It's a soul.

위성 통신의 사용 증가에 따라 고이득 특성을 갖는 위성용 안테나의 사용이 증가하면서 차량, 선박, 항공기, 기차 등에 탑재 가능한 고이득 반사경 안테나 개발이 요구되어지고 있다. 고 이득을 얻기 위해서는 원형 형태의 반사경(4) 크기의 증가가 요구되어지므로 반사경 높이를 최소화하기 위해 비대칭형 빔폭을 갖는 피드혼이 요구되어 진다.As the use of satellite communication increases, the use of satellite antennas having high gain characteristics is increasing, and there is a demand for developing high gain reflector antennas that can be mounted on vehicles, ships, aircrafts, trains, and the like. In order to obtain a high gain, an increase in the size of the circular reflector 4 is required, so a feed horn having an asymmetric beam width is required to minimize the reflector height.

본 고안과 같은 목적으로서 H-plane 피드혼이나 피드혼의 내부에 유전체나 구조물을 첨가한 sectoral horn이 개발되어 있다. 그러나 이러한 피드혼들은 목적에 따라 피드혼을 다시 설계하여 제작해야한다는 것, 구조의 복잡함, 그리고 능동적인 빔폭을 조절함에 있어 피드혼 전체의 구조를 재설계해야 한다는 단점들이 있다. For the same purpose of the present invention, a sectoral horn has been developed in which an dielectric or a structure is added to an H-plane feed horn or the inside of the feed horn. However, these feed horns have the disadvantage of having to redesign and manufacture the feed horn according to the purpose, the complexity of the structure, and the redesign of the entire feed horn in the active beam width control.

본 고안이 이루고자 하는 기술적 과제는 기존의 개발된 피드혼에 비교적 단순한 칸막이 구조(3)를 추가함으로써 비용의 절감 효과와 더불어 수평 방향으로 넓은 빔폭을 요구하는 특수 목적용이나, 반사경 안테나의 높이를 최소화 하면서 이득을 극대화시키기 위한 피드혼 설계의 기법을 제시하고자 함이다.The technical problem of the present invention is to add a relatively simple partition structure (3) to the conventionally developed feed horn and to reduce the cost and to minimize the height of the reflector antenna for special purposes requiring a wide beam width in the horizontal direction. In this paper, we propose a technique of feed horn design to maximize the gain.

본 고안은 도1 에서와 같은 기존의 개발된 피드혼의 개구면(1)에 도2와 같이 비교적 간단한 칸막이 구조(3)를 설치하는 것이다. 피드혼의 E-field 방향과 동일하게 칸막이 구조를 설치하고 칸막이 사이의 간격(2)을 조절하여 원하는 비대칭 빔폭을 구현할 수 있다. 칸막이구조는 피드혼의 개구면(1)에 칸막이 구조(3)를 설치한 cap을 씌우거나 피드혼의 개구면(1)에 직접 납땜을 하여 설치할 수 있다.The present invention is to install a relatively simple partition structure 3 as shown in Fig. 2 on the opening face 1 of the conventionally developed feed horn as shown in Fig. 1. In the same manner as in the E-field direction of the feed horn, a partition structure may be installed and a gap 2 between the partitions may be adjusted to achieve a desired asymmetric beam width. The partition structure can be installed by capping the partition structure 3 on the opening face 1 of the feed horn or by soldering directly to the opening face 1 of the feed horn.

이상에서와 같이 본 고안에 의하면, 수평 방향으로 넓은 빔폭을 요구하는 특수 목적용이나 반사경의 높이를 최소화 하는 것에 있어서 피드혼의 재설계 및 제작의 필요 없이 기존의 개발된 피드혼(1)에 칸막이 구조물(3)을 첨가하여 사용함으로써 비용 절감 효과와 안테나의 효율 증가를 가져올 수 있다.As described above, according to the present invention, the partition structure of the existing developed feed horn (1) without the need for redesign and manufacture of the feed horn in minimizing the height of the special purpose or reflector that requires a wide beam width in the horizontal direction Adding and using (3) can reduce the cost and increase the efficiency of the antenna.
