상기한 목적을 이루기 위하여 본 발명의 구성은 3장의 마이크로 스트립 안테나(도3,도4,도5)를 도2와 같이 겹쳐서 하나의 안테나 형태로 제작 하였다.In order to achieve the above object, the configuration of the present invention was made by stacking three microstrip antennas (FIGS. 3, 4, 5) as shown in FIG.

도3의 KA(K)-BAND(18Ghz~40Ghz)용 평면 안테나는 유전율이(E)이 3.0 이하인 프린트 기판을 사용 하여 파장에 맞추어 패치어레이에 스트립 라인을 연결하는 방식으로 설계한 안테나로 독립적 KA(K)-BAND용 안테나로도 사용이 가능하다.The planar antenna for KA (K) -BAND (18Ghz ~ 40Ghz) of FIG. 3 is an antenna designed by connecting strip lines to a patch array according to a wavelength using a printed board having a dielectric constant (E) of 3.0 or less. It can also be used as an antenna for (K) -BAND.

도4의 KU(X)-BAND(8Ghz~18Ghz)용 평면 안테나는 유전율이(E)이 3.0 이하인 프린트 기판을 사용 하여 파장에 맞추어 패치어레이에 스트립 라인을 연결하는 방식으로 설계한 안테나로 독립적 KU(X)-BAND용 안테나로도 사용이 가능하다The flat antenna for KU (X) -BAND (8Ghz ~ 18Ghz) of FIG. 4 is an antenna designed by connecting strip lines to patch arrays according to the wavelengths using a printed board having a dielectric constant (E) of 3.0 or less. Can also be used as an antenna for (X) -BAND

도3의 C-BAND(4Ghz~8Ghz)용 평면 안테나는 유전율이(E)이 3.0 이하인 프린트 기판을 사용 하여 파장에 맞추어 패치어레이에 스트립 라인을 연결하는 방식으로 설계한 안테나로 독립적 KA(K)-BAND용 안테나로도 사용이 가능하다.The planar antenna for C-BAND (4Ghz ~ 8Ghz) of FIG. 3 is an antenna designed by connecting a strip line to a patch array in accordance with a wavelength using a printed board having a dielectric constant (E) of 3.0 or less. Can also be used as a BAND antenna.

각각 제작된 3개의 평면 안테나를 도2와 같이 상층에는 KA(K)-BAND, 중간에는KU(X)-BAND, 그리고 하층에 C-BAND용 안테나를 배열 하였으며 하나의 안테나로 설계하였다. 이에대한 평면도를 도1, 측면도를 도2에 나타내었으며, 전파가 수신되는 정면에서 KA(K)-BAND와 KU(X)-BAND 주파수 신호가 서로 간섭되지 않는 구조로 배치 되어 있으며 C-BAND 안테나는 KA(K)-BAND 안테나의 패치 어레이를 겹쳐서 전파를 수신 한다.As shown in FIG. 2, the three planar antennas manufactured were arranged in the upper layer with the KA (K) -BAND, the middle with the KU (X) -BAND, and the lower layer with the C-BAND antenna. A plan view of the present invention is shown in FIG. 1 and a side view of FIG. 2, and in a structure in which the KA (K) -BAND and KU (X) -BAND frequency signals are not interfered with each other at the front side where radio waves are received, and the C-BAND antenna Receives radio waves by superimposing a patch array of the KA (K) -BAND antenna.

이와 같이 각 주파수 BAND 별로 지향성 다이어램 방향에 맞추어 엘리먼트와 피드라인을 배열하고 도6의 결합회로를 통하여 각 BAND 용 CONVERTOR로 연결하면 다중 전파수신이 가능한 통합안테나 된다.As such, when elements and feed lines are arranged in accordance with the direction of the directional diaphragm for each frequency band, and connected to each BAND CONVERTOR through the coupling circuit of FIG. 6, an integrated antenna capable of multiple radio reception is possible.

각층별 회로를 구성 하였을때 안테나의 효율을 나타내는 전압정재파비(VSWR)는 1.5 이하를 얻었고 이득은(GAIN)은 30db 이상을 얻수 있으며 아울러 이득이 더 큰안테나를 패치 엘리먼트의 수를 증가는 방법으로 확장 설계가 가능하다. 다층 구조를 가진 안테나 이므로 패치 엘리먼트의 간격과 스트립라인 구조를 조정하여 빔의 지향성 빔폭을 최소화 하여야 가장 이상적인 통합 안테나를 만든다.The voltage standing wave ratio (VSWR), which represents the efficiency of the antenna, is obtained when the circuit for each layer is composed of 1.5 or less, and the gain (GAIN) is more than 30db, and the antenna with larger gain is increased by increasing the number of patch elements. Extended design is possible. Since the antenna has a multilayer structure, the gap between the patch elements and the stripline structure must be adjusted to minimize the directional beam width of the beam to create the most ideal integrated antenna.

본 발명은 통합안테나(C-BAND,KU(X)-BAND,KA(K)-BAND)로서 기존 여러개의 위성용 안테나를 사용 하던 것을 한개의 안테나로 만들어 비용 절감, 설치공간 용이,소형화등 의 기대 효과를 가지게 되며 아울러 위성통신용 통합 안테나로서 새로운 통신 방식의 창출이 가능 할것이다.The present invention is an integrated antenna (C-BAND, KU (X) -BAND, KA (K) -BAND) by using the existing antennas for multiple satellites as one antenna, cost reduction, easy installation space, miniaturization, etc. In addition, it will be possible to create a new communication method as an integrated antenna for satellite communication.
