Research On Multiple Beam Scanning Antenna Controled By Electricity

Multi-beam antenna is broadly applied in modern communication system in recent years,especially in satellite communication,remote sensing detection and missile guidance.Electronically scan technology is used to study on the multi-beam antenna array,Speed-sensitive switch with the appropriate beam is adopted to real-time control and communication,which is applied to the action zone that simultaneously covered the measurement and control communication of multiple unmanned aerial vehicles at once time in the air.Time division,frequency division and space division are taken to achieve the fast switching antenna according to the real-time azimuth of multiple unmanned aerial vehicles.It is blank for the application of multi-beam scanning radio measurement and control technology at present in China,the study is aimed to solve the problem of measurement and control on COSCO distance multiple unmanned aerial vehicles in the air,which is research prospect and engineering value.The parameter of Electronically controlled multi-beam scanning array antenna are analyzed and summarized in the paper,and in order to its engineering application,partial calibration methods are optimized.The performance antenna,between H1～H2 GHz are all more than 18.0 dBi and beam width are all above 15°,and the radiant efficiency is 360above,which conforms to design index.
