摘要
针对传统的波导缝隙天线和微带贴片天线在毫米波段所存在的缺点 ,本文提出利用印刷工艺来制造毫米波波导缝隙天线。与以往的结构相比 ,新结构不仅可以提供满足毫米波段应用的精度和较低的成本 ,而且可以在一定程度上抑制旁瓣电平。基于这种结构 ,本文设计并制作了 Ka波段的两种波导缝隙天线。实验结果和设计结果吻合 。
In view of the drawback of traditional slot and microstrip patch antenna,a new type of rectangular waveguide slot antenna with print technology is presented in this paper.Compared with the previous structure,the later is more precise and of lower cost.Two kinds of slot antennas at Ka band have been designed and tested.The experimental results show well agreement with designed specifications.
