Abstract
本实用新型涉及脊波导宽边“V”字形缝隙天线。该天线的辐射波导管的上面宽边金属波导壁上设有等间距两个以上的辐射缝隙；其为横截面呈“凹”形的金属脊波导管，所述辐射缝隙呈“V”字形，且相邻的“V”字辐射缝隙按对称方式排列。辐射波导管一端为天线输入口，另一端封闭短路，构成波导缝隙驻波阵。本实用新型天线结构尺寸小，波导管的横截面积压缩了一半以上；可以实现全空间交叉极化抑制；该天线波导结构易于采用同样横截面的波导功分器简单的上下叠加，实现宽带波导缝隙天线阵，加工工艺好，易于与传统的波导宽边纵向辐射缝隙天线组成双极化天线阵。
English (machine translation): The utility model relates to a "V"-shaped slot antenna with a broad side of a ridge waveguide. The upper wide-side metal waveguide wall of the radiation waveguide of the antenna is provided with more than two radiation slots at equal intervals; it is a metal ridge waveguide with a "concave" cross-section, and the radiation slots are in a "V" shape. And the adjacent "V" radiation slots are arranged symmetrically. One end of the radiation waveguide is the antenna input port, and the other end is closed and short-circuited to form a waveguide slot standing wave array.…
