Description
본 발명은 위성 통신 안테나 외곽 하우징 부착필름에 관한 것으로서, 최상단에 위치되는 ETFE 필름층(110);과, 상기 ETFE 필름층(110)의 하부면에 도포되는 접착층(120);과, 상기 접착층(120)의 하부면에 합지되는 백킹필름층(130); 및 상기 백킹필름층(130)의 하부면에 도포되는 점착층(140);으로 구성되는 것을 특징으로 하는 위성 통신 안테나 외곽 하우징 부착필름에 관한 것이다.The present invention relates to a satellite communication antenna outer housing attachment film, comprising: an ETFE film layer 110 located at the top; an adhesive layer 120 applied to the lower surface of the ETFE film layer 110; and the adhesive layer ( A backing film layer 130 laminated to the lower surface of 120); and an adhesive layer (140) applied to the lower surface of the backing film layer (130).
일반적으로, 위성통신(衛星通信, satellite communications)이란 통신위성을 이용하여 제공하는 통신서비스 또는 그와 관련된 학문 및 기술의 총체를 의미한다.In general, satellite communications refers to communication services provided using communication satellites or the entirety of studies and technologies related thereto.
인공위성은 용도에 따라 군사위성, 기상위성, 과학위성, 통신위성 등으로 나눌 수 있는데 통신위성이란 통신 신호를 중계할 목적으로 지구를 돌고 있는 인공위성을 말한다.Artificial satellites can be divided into military satellites, meteorological satellites, scientific satellites, and communication satellites depending on their purpose. Communication satellites are artificial satellites orbiting the Earth for the purpose of relaying communication signals.
한편, 위성과의 통신은 전리층을 통과해야 하므로 주파수가 1GHz 이상으로 높은 마이크로파를 사용한다. 1.6/1.5GHz1)의 L대역은 저궤도 위성용, 2.6/2.5GHz의 S대역은 위성관제용, 6/4GHz의 C대역은 정지궤도 위성용, 8/7GHz의 X대역은 군사용, 14/12GHz인 Ku대역은 정지궤도 위성용 등으로 할당되어 있다. 최근에는 그동안 기상에 따른 감쇄가 심해 별로 관심을 받지 못했던 26.5GHz~40GHz의 Ka대역의 상업적 이용이 활발해지고 있다.Meanwhile, since communication with satellites must pass through the ionosphere, microwaves with a frequency of 1 GHz or higher are used. The L band of 1.6/1.5GHz1) is for low-orbit satellites, the S-band of 2.6/2.5GHz is for satellite control, the C-band of 6/4GHz is for geostationary satellites, the X-band of 8/7GHz is for military use, and the Ku band of 14/12GHz is for military use. is allocated for geostationary satellites, etc. Recently, commercial use of the Ka band from 26.5 GHz to 40 GHz, which has not received much attention due to severe attenuation due to weather, is becoming more active.
이러한 위성통신 시스템은 일반적으로 지구국, 위성, 위성 중계기, 지상 관제소의 요소로 이루어져 있다. 지구국(earth station)이란 지상에서 위성으로 데이터를 전송하고 또 위성으로부터 데이터를 수신하는 장치이다. 지구국은 전송하고자 하는 정보를 입력받아 이를 위성으로 전송하기에 적절한 형태로 변조한 후 신호를 증폭하여 안테나를 통해 위성으로 전송한다. 안테나는 지향성이 좋아야 하므로 대개는 보통 접시 안테나라고 부르는 카세그레인 안테나(cassegrain antenna)를 사용한다. 하지만 기지국이 소형이어서 실장에 문제가 있는 경우에는 헬리컬 안테나(helical antenna) 등을 사용하기도 한다.These satellite communication systems generally consist of the elements of an earth station, satellite, satellite repeater, and ground control station. An earth station is a device that transmits data from the ground to a satellite and receives data from the satellite. The earth station receives the information it wants to transmit, modulates it into a form suitable for transmission to the satellite, amplifies the signal, and transmits it to the satellite through an antenna. Since the antenna must have good directivity, a cassegrain antenna, commonly called a dish antenna, is usually used. However, if the base station is small and there are problems with mounting, a helical antenna may be used.
한편, 기존 위성 통신 안테나의 표면에는 원활한 수신기능확보 및 표면보호를 위하여 ETFE(Ethylene Tetra fluoro Ethylene)와 에폭시 소재로 이루어진 필름이 부착되어 있다.Meanwhile, a film made of ETFE (Ethylene Tetra fluoro Ethylene) and epoxy material is attached to the surface of the existing satellite communication antenna to ensure smooth reception function and protect the surface.
그러나, 기존 위성 통신 안테나에 적용되는 ETFE 필름은 에폭시 가사시간이 짧음으로 생기는 기포발생 등으로 인하여 공정 수율이 낮았으며, 대량생산이 불가능하다는 문제점이 있었다.However, the ETFE film applied to existing satellite communication antennas had a low process yield due to the generation of bubbles caused by a short epoxy pot life, and there was a problem that mass production was impossible.
또한, ETFE 특성상 낮은 경도와 연신율에 의한 수축, 이완의 발생이 커서 외부충격에 의한 표면손상이 쉽게 발생하고, 가공공정시 치수 불량률이 높다는 문제점이 있었다.In addition, due to the characteristics of ETFE, there was a problem that shrinkage and relaxation due to low hardness and elongation were large, so surface damage due to external shock easily occurred, and the dimensional defect rate was high during the processing process.
본 발명은 상술한 문제점을 해결하고자 안출된 것으로서, 본 발명의 목적은 ETFE층의 하부에 PET층 및 점착층을 합지하여 스티커부착타입의 필름을 형성함으로써, 필름의 경도율을 확보하고, 연신율을 낮게 함으로써, 외부충격에 의한 표면손상을 줄여주고, 가공공정시 정확한 치수로 가공이 가능하게 하는 위성 통신 안테나 외곽 하우징 부착필름을 제공하는 것이다.The present invention was developed to solve the above-mentioned problems. The purpose of the present invention is to secure the hardness of the film and increase the elongation by forming a sticker-type film by laminating the PET layer and the adhesive layer on the lower part of the ETFE layer. By making it low, it reduces surface damage caused by external impact and provides a satellite communication antenna outer housing attachment film that enables processing to accurate dimensions during the processing process.
상기와 같은 문제점을 해결하기 위하여, 본 발명에 따른 위성 통신 안테나 외곽 하우징 부착필름은, 최상단에 위치되는 ETFE 필름층(110);과, 상기 ETFE 필름층(110)의 하부면에 도포되는 접착층(120);과, 상기 접착층(120)의 하부면에 합지되는 백킹필름층(130); 및 상기 백킹필름층(130)의 하부면에 도포되는 점착층(140);으로 구성되는 것을 특징으로 한다.In order to solve the above problems, the satellite communication antenna outer housing attachment film according to the present invention includes an ETFE film layer 110 located at the top; and an adhesive layer applied to the lower surface of the ETFE film layer 110 ( 120); And, a backing film layer 130 laminated to the lower surface of the adhesive layer 120; And an adhesive layer 140 applied to the lower surface of the backing film layer 130.
또한, 상기 백킹필름층(130)은, Polyester로 이루어지고, 두께는 35μm∼38μm로 이루어진 것을 특징으로 한다.In addition, the backing film layer 130 is made of polyester and has a thickness of 35 μm to 38 μm.
또한, 상기 점착층(140)은 실리콘계열의 소재로 이루어지는 것을 특징으로 한다.In addition, the adhesive layer 140 is characterized by being made of a silicon-based material.
또한, 상기 점착층(140)의 표면은 요철패턴이 적용되는 것을 특징으로 한다.In addition, the surface of the adhesive layer 140 is characterized in that a concavo-convex pattern is applied.
또한, 상기 점착층(140)의 하부면에는 이형지가 합지되는 것을 특징으로 한다.In addition, the lower surface of the adhesive layer 140 is characterized in that release paper is laminated.
이상, 상술한 바와 같이 본 발명에 따르면, ETFE층의 하부에 PET층 및 점착층을 합지하여 스티커부착타입의 필름을 형성함으로써, 필름의 경도율을 확보하고, 연신율을 낮게 함으로써, 외부충격에 의한 표면손상을 줄여주고, 가공공정시 정확한 치수로 가공이 가능하다는 장점이 있다.As described above, according to the present invention, the PET layer and the adhesive layer are laminated on the lower part of the ETFE layer to form a sticker-type film, thereby securing the hardness of the film and lowering the elongation, thereby reducing the risk of external shock. It has the advantage of reducing surface damage and enabling processing to precise dimensions during the processing process.
또한, 본딩 부착방식이 아닌 스티커 부착방식으로 필름을 구성함으로써, 기존 대비 공정수율 및 생산량이 증가된다는 장점이 있다.In addition, there is an advantage in that the process yield and production volume are increased compared to the existing method by constructing the film using a sticker attachment method rather than a bonding attachment method.
