| 摘 要： | 设计了基于双层频率选择表面FSS(Frequency Selective Surfaces)的高增益微带天线.基于双调谐峰原理,设计了具有良好频率选择特性的双层FSS,将其作为微带天线的覆层,制备了一种X波段高增益新型微带天线.利用射线理论,分析了新型天线的工作机理,并通过实测对仿真结果进行了验证.实验结果表明:相比于传统微带天线,加载覆层后的新型天线带宽没有变化,而其方向性得到了明显改善,鼻锥方向增益提高了6.6dB.

| Abstract: | A high-gain microstrip antenna based on double layer FSS is designed. Double layer FSS is equal to twodifferent resonance cells. The Frequency selective characteristic is effectively improved by producing double tuned peaks. Anew microstrip antenna is fabricated via using the double layer FSS as the overlying strata, and analysising how does the newantenna work by the ray theory. The results of simulating and measuring demonstrate that: the directivity of the antenna isenhance and the gain of proposed microdtrip antenna is enhanced by 6. 6dB. |
