提出了一种基于平面基片集成波导喇叭馈电的带状金属栅漏波天线。通过采用金属通孔矫正技术,喇叭口径具有几乎一致的相位分布,同时平面喇叭能够与漏波天线在同一介质板上实现,因此这种馈电结构的漏波天线具有良好的阻抗匹配特性。仿真结果表明,本文设计的天线在15.3~17.4GHz频段范围内反射系数低于-10d B,相对带宽约为12.9%。同时,与理想波导馈电结构相比,该天线的介质损耗小于1d B。
A strip-shaped metal grid leaky-wave antenna based on a planar substrate integrated waveguide horn is proposed. By adopting metal through-hole correction technology, the horn diameter has almost the same phase distribution, and the planar horn can be realized on the same dielectric board as the leaky wave antenna. Therefore, the leaky wave antenna of the feed structure has good impedance matching characteristics. The simulation results show that the designed antenna has a reflection coefficient of less than -10d B in the range of 15.3 ~ 17.4GHz, and the relative bandwidth is about 12.9%. At the same time, the dielectric loss of the antenna is less than 1d B compared to an ideal waveguide feed structure.
