在本文中，我们提出了一个开槽波导阵列天线覆盖的介质板与后壁腔。基于驻波激励的谐振串联缝隙阵列天线的阻抗匹配可以容易地实现。此外，它表明，所提出的天线的方向图形状大大改善，并通过使用后壁腔的方向性增强。
In this paper, we propose a slotted waveguide array antenna covered by a dielectric slab with a post-wall cavity. The impedance matching of a resonant series slot array antenna based on a standing wave excitation can be easily achieved. Moreover, it is shown that the pattern shape of the proposed antenna is greatly improved and the directivity is enhanced by using the post-wall cavity.
