双频圆极化缝隙加载微带天线

双频圆极化缝隙加载微带天线

内容简介：文章提出了一种三角形缝隙微带天线,在贴片表面开槽实现了双频,且天线能够工作在Ls波段和S波段上,并保证了相应的带宽;通过截去三角形的一角和选择合适的馈电点,实现了天线的圆极化,同时也展宽了轴比带宽;通过理论分析和计算机优化,给出了天线的具体参数。

Abstract：A dual-frequency triangular slot microstrip antenna is proposed in this paper.Theoretical analysis and simulation show that slot-loaded and triangle patch with truncated corner can realize dual-frequency and circular polarization,which enhances the axial ratio bandwidth and overall size of the antenna.
