摘　　要：微带天线的窄频特性是限制它广泛应用的原因之一。为增大微带天线的阻抗带宽,综合运用了缝隙耦合的馈电方式、双层贴片结构,在叠层贴片间引入空气层等技术,设计了一种适用于Ku波段的宽频带天线单元,并由该单元组成了十六元微带天线阵以获得高增益阵列,最后制作了实验模型。测量结果表明与仿真结果一致。The narrow bandwidth property of a microstrip antenna is one of the important reasons to restrict its wide application. Aperture-coupled feeding, stacked patches structure are used to enhance the bandwidth of mierostrip antenna element at Ku band. The element is simulated and optimised. A 16-element array antenna, which is composed of the antenna element, is simulated and made. The measured results show that the relative impedance bandwidth of the array is about 14.4% （VSWR 〈1.5）, and the gain is about 18 dB. From the measured results, it is agree basically with the simulation results.
