摘要
利用等离子体对电磁波的独特响应,设计了一种可工作于30~512 MHz的新型超宽带等离子体天线。给出了等离子体天线的设计方法,说明了天线的系统组成,采用新形式及阻抗匹配网络实现了天线良好匹配;分析了等离子体天线的低雷达散射截面(RCS)特性;突破关键技术,研制了一套超宽带等离子体天线样机,测试了天线的匹配和辐射特性,测试结果与仿真结果互相吻合。研究成果可推广应用于各类低RCS载体平台的微波通信天线系统中。
Based on the specific response of plasma to the electromagnetic wave,a new wideband plasma antenna operating in 30~512 MHz is designed.The design method of the plasma antenna is given.The composition of the antenna is described.A new structure and the impedance matching network are used to achieve good impedance matching of the antenna.The low Radar Cross Section(RCS)characteristics are analyzed.A prototype of the ultra-wideband plasma antenna is developed to test the matching and radiation characteristics of the antenna.The test results are fit with the design result.The research results can be extended to all kinds of microwave communication antenna systems on carriers with low RCS.
