A Study on the Vehicle Digital Broadcasting System of Active Electronic Control Method using Phase Shifter

위상변위기를 이용한 능동전자제어방식의 차량용 디지털 위성방송 시스템에 관한 연구

In this paper, it is proposed the phase shifter array active system to receive digital satellite broadcasting for vehicle. To receive satellite broadcasting data in vehicle, it is inevitable to have active antenna system, which traces the satellite in real time. Also if it is used in vehicle, it must be thin and light structure. To develop this type of antenna system, several techniques should be integrated properly. These are the design and manufacturing technique of high gain antenna, algorithm for tracking satellite and its manufacturing technique, controller design and manufacturing technique, system integration technique and so on. The validity of the proposed AVDBS system was confirmed by simulation and experimental results.
