| 摘 要： | 基于机载合成孔径雷达系统的具体应用,给出一种C波段宽带二维扫描固态有源相控阵天线的设计与实现方案. 该天线辐射阵面采用双层矩形微带贴片,由宽带偶极子激励. 通过增加金属隔墙和金属接地螺钉的加载来降低天线单元间互耦,实现了宽带二维相控扫描. 测试结果表明,辐射单元阵中驻波带宽(VSWR<1.6) 达到800 MHz(相对带宽约15%).

| Abstract: | A C-band wide-band 2-dimensional scanning solid-state active phased array antenna for airborne synthetic aperture radar (SAR) is designed. Microstrip patch is used and excited by a wide-band dipole. Metal walls and metal grounding screws are used to reduce the mutual couplings between microstrip antenna elements. The measure results indicate that the bandwidth of the antenna exceeds 800 MHz (VSWR<1.6). |
