双波段遥测天线设计

随着航空飞行试验数据量的不断增加，原有IRIG106遥测系统已不能完全适应当前和未来的需求。同时随着网络技术的不断发展，遥测系统的网络化成为新的发展趋势。民用4G通信占用S波段遥测资源使得航空遥测寻找新的传输频段。为了充分利用和保护现有资源，并适应遥测的网络化发展，本文提出在现有S波段遥测基础上增加C波段网络数据传输功能，开展双波段遥测天线设计技术研究。在对天线结构进行合理设计的基础上，提出了一体化馈源设计方案。通过S波段振子与C波段振子的集成化设计，实现了C波段无线网数据与S波段串行数据流的共同传输，极大地提高了遥测数据传输速率，缓解了遥测频率资源紧张的现状。通过飞行试验验证，设计的双波段天线能够满足飞行试验大速率数据的传输需求。

Design of Dual-band Telemetry Antenna

With the continuous development of telemetry network, it is necessary to increase the C-band network data transmission function on the basis of S-band telemetry. Dual-band telemetry antenna design techniques research has doing. Base on the properly design of antenna structure, the integrated feed design project is proposed. Through the integrated design of S-band and C-band dipoles, Common transmission of C-band wireless network data and S-band telemetry data has implemented. Telemetry data rate has been improved and the absence of telemetry frequency resource has been alleviated. Verified by flight tests, the design of dual band antenna can meet the transmission requirements of high rate data.
