一种波导缝隙耦合馈电的微带天线阵

A Waveguide Slot Coupling Fed Microstrip Antenna Array

设计了了一种新型的微带天线阵。该天线阵采用矩形波导宽边纵向缝隙耦合微带线结构给串馈微带贴片线阵馈电,从而构成二维平面阵。利用软件CST对波导缝隙-微带线耦合结构和微带串馈线阵进行了仿真设计,并制作了一个X波段16×16元天线阵,测量结果证明了分析设计方法的正确性。

A novel microstrip antenna array is designed.Rectangle metal waveguide slot-microstrip coupling structure is used to feed series-fed microstrip patch linear array,thus a planar array is obtained.The simulation result of waveguide slot-microstrip coupling structure and series-fed microstrip patch linear array with the software CST are presented.An X-band array consisting of 16×16 elements is fabricated,the measemental results show that the analysis and design method are correct.
