Antenna Array Technology For UAV Ground Tt&c System

In recent years, unmanned aerial vehicle(UAV) technology and its application had become a developing technology which was paid attention by all countries in the world. UAV was developing towards series and systematization. Intermediate and short-range unmanned aerial vehicle(UAV)had become UAV main applications for its low cost of the use and development, and for needless of airport runway or dedicated runway,and meanwhile intermediate and short-range unmanned aerial vehicle had low takeoff and landing requirements, take-off and landing of the small risk. The UAV ground control stationwas the indispensable part of the UAV system, and now was developing towards light-duty vehicle and portabletype. At the same time the study of muli-UAV telemetry track and command(TT&C) system had been paid for more and more attention. For the important channel machine of the muli-UAV TT&C, the research of antenna array technology for UAV TT&C ground stationhad very important significance.On the basis of the antenna technology for UAV TT&C ground station, deep study of the UAV TT&C antenna technology was presented in this paper, and the paper would demonstrate the detail design scheme and design simulation of the antenna and multi-beam network with the engineering practice.The main content is asfollows:UAV TT&C technology in China was presented first, and technical difficulties and solutions of muli-UAV one station TT&C antenna array technology were in this paper.Implementation scheme of the muli-UAV one station array antenna were presented in this paper, and the design scheme was done about the light-duty, portable UAV TT&C array antenna. Working principle and broadband design method of the microstrip antenna and fixed multibeam passive network were showed in this paper, and this paper also demonstrate the system analysis of the time division multiple beam based on phased array and the matrix of passive butler multi-beam system. Technical requirements of the relevant part had been identified in the paper, and the simulation of the antenna unit, butler matrix and direction of the diagram after group array with the help of the HFSS and Ansoft Designer were presented in the paper, and had done the analysis and summary for the simulation results.In the final parts, detailed index test and analysis had been done for the complete part of the component, and test results could fit the system requirement well for the small size, light weight and good performance. This paper had provided important technical reserves for the improvement and finalization of the principle prototype design.
