摘要: 高可靠性对于星载天线至关重要,印制馈线和焊点往往会严重降低天线的工程可靠性.针对这一问题,本文以超宽带圆锥螺旋天线的设计为例,强化电气、结构和工艺协同设计思想,通过改进传统巴伦结构,提出了电缆、巴伦和螺旋线一体化的无焊接设计方案.仿真结果表明,所设计的天线在整个工作频段内具有良好的宽角高增益覆盖、宽角圆极化特性和前后比指标.

关键词: 圆锥螺旋天线, 宽带宽角, 高增益, 一体化

Abstract: High reliability is essential for spaceborne antenna,however PCB feeder and solder joint are usually lacking of guarantee in reliability.Therefore,a integrative and solderless design of cable,balun and spital is proposed using improved balun,intensifying the cooperative design idea of electricity,structure and technology.As a example,a UWB conical spiral antenna is designed.The simulated results show that the antenna achieves a wide-angle coverage with high gain and low axial ratio,as same as high front-to-back ratios.

Key words: conical spiral antenna, wide-band and wide-beam, high gain, integration
