摘　　要：提出了一种采用波导缝隙和微带线共同给X波段微带贴片天线阵馈电的新型方式。用NFDTD对这种面阵进行数值仿真和设计。已制作出的天线阵的实测结果表明其效率可达68.5%。A novel feed method for X-band microstrip patch arrays is presented. It is accomplished by combining a slotted waveguide and microstrip lines to feed the array. The antenna is designed by the NFDTD simulation, and the tested efficiency of the antenna fabricated reaches 68.5%.

关 键 词：微带天线阵 波导缝隙 口径耦合 串联馈电
