Abstract
本发明涉及中心馈电脊波导缝隙天线，在脊波导有脊的一面，在脊的两侧交错开缝形成缝隙阵，与缝隙相对的脊的另一侧放置金属调谐块，金属调谐块紧贴金属脊与波导面，用于调节辐射缝隙的等效导纳并使辐射缝隙的等效电纳为零，使辐射缝隙处于谐振状态，波导的激励采用中心馈电的方式以展宽带宽，由于激励位置位于脊波导非加脊的一面，可以采用同轴探针底馈的方式，也可以采用波导中心倾斜缝背馈等常规的波导馈电方式；本发明中心馈电脊波导缝隙天线提出了一种波导缝隙天线的新形式，可以实现低副瓣，且结构紧凑，馈电方式简单，易于加工，可以作为相控阵天线的组阵单元。
English (machine translation): The invention relates to a center-feed ridge waveguide slot antenna. According to the center-feed ridge waveguide slot antenna, a slot array is formed on a ridged face of a ridge waveguide in a manner that two sides of a ridge are slotted in a staggering manner, and metallic tuning blocks are placed at the other side of the ridge opposite to slots, clung to the metallic ridge and a face of the waveguide, and used for adjusting the equivalent admittance of the radiation slots, so that the equivalent susceptance of the radiation slots is enabled to be zero, and the radiation slots are enabled to…
