摘要
研究了一种X波段16单元矩形径向线螺旋阵列天线。介绍了该矩形阵列天线的提出背景以及工作原理,分析了两种电磁耦合探针在X波段的耦合特性,开展了扼流结构与电磁耦合探针的协同设计,设计并数值模拟了中心频率为9.3 GHz的16单元矩形径向线螺旋阵列天线,并进行实验测试。测试结果表明:该口径为96 mm×96 mm的天线在中心频率9.3 GHz下,增益为19.51 dB,轴向轴比值1.05,驻波系数1.17。
The paper studies an X-band 16-element square helical array antenna.It introduces the background of the rectangular array antenna and the working principle,analyzes coupling characteristics of two kinds ot electromagnetic coupling probes in the X-band.A collaborative design of the choke structure and the electromagnetic coupling probe was conducted,the 16-element square helical array antenna with a center frequency of 9.3 GHz was designed and simulated.Simulation results show that：the antenna diameter is 96 mm×96 mm,with center frequency 9.3 GHz,the gain is 19.51 dB,the axial ratio is 1.05,the reflection coefficient is less than 0.15.
