微带-缝隙馈电的渐变缝隙天线及其阵列应用

Research on the Tapered Slot Antenna Fed by Microstrip-Slotline Transition and the Array Application

介绍了一种以斜角微带-缝隙过渡馈电的Ka波段渐变缝隙天线。这种馈电方式在阵列应用中有很大的优势,因为天线阵和馈线可一次印刷制造,并且也易于和其后的电路集成。使用这种馈电方式和一组PIN开关实现了一组线阵共用同一接收机通道的效果,对于毫米波阵列成像系统研究具有重要的意义。

The Ka band tapered slot antenna fed by inclined microstrip - slotline transition was introduced. The feed method is preponderant in the array application, because the antennas and the feed lines can he manufactured in print at one time, and they can he integrated with other circuits easily, Using the feed method, the line array whose units share a common receiver channel with a group of PINs was designed, which will be beneficial to the research of MMW image by array.
