摘　　要：该文通过结合经验公式和全波分析法,设计了一种电容补偿双层贴片、四层介质的微带贴片天线单元,该单元天线在频率为995～1125MHz的范围内,在驻波比SWR<1.5的情况下,相对阻抗带宽达到12.26％的工程要求。此外,该文给出由该单元天线组成的2×16天线阵以及天线阵的驻波比的实测结果,最后给出天线阵的各单元排列方式和单元之间的互耦特性曲线的实测结果。A stacked double-patch arid four-layer substrate microstrip antenna with the capacitance compensation probe feed is designed by combining the experimental formulae and the full-wave method. The relative impedance bandwidth of this microstrip antenna reaches up to 12.26% in the frequency band between 995MHz and 1125MHz under the condition that SWR is less than 1.5. In addition, a 2×16 array composed by this kind of microstrip antenna is presented and the experimental results of the SWR are given too. Finally, the arrangement of elements in the antenna array and the experimental results of the mutual coupling between elements are given.
