摘　　要：设计了一种可应用于宽带宽角扫描相控阵雷达的低剖面阵列天线,该天线采用“L”形探针馈电开槽贴片天线作为阵列单元,借助ANSYS HFSS仿真设计了9×9阵列天线,使该阵列天线在工作带宽3.16 GHz内,E面、H面扫描角度达到±50°。该天线剖面低、重量轻、宽带宽角扫描性能优异,在相控阵雷达天线中具有很好的应用前景。A low profile array antenna can be used for broadband wide-angle scanning phased array radar is designed.The antenna uses an L-shaped probe-fed slotted patch antenna as the array unit,and the 9×9 array antenna is simulated and designed with the help of ANSYS HFSS,so that the array antenna can reach±50°scanning angle of E plane and H plane within the working bandwidth of 3.16 GHz.The antenna has low profile,light weight and excellent broadband wide-angle scanning performance,and has a good application prospect in phased array radar antennas.
