Medium waveguide crack array antenna with series feed of metal hollow waveguide

The invention relates to the technical field of antenna designs and particularly relates to a medium waveguide crack array antenna with series feed of a metal hollow waveguide. According to the medium waveguide crack array antenna, the metal hollow waveguide is used as a crack array antenna of a feed device; compared with a traditional medium waveguide feed manner, a feed manner adopted by the invention has small loss; meanwhile, the metal hollow waveguide feed device does not adopt a traditional plane feed manner, and the feed device is independently arranged and is fixed with upper and lower layers of an antenna medium layer, so that a feed line does not occupy a surface area of the medium layer, and furthermore, the surface of the medium layer can be used for arranging antenna radiation cracks and the surface utilization rate of the medium layer is greatly improved. 本发明涉及天线设计技术领域，特别涉及种金属空心波导串联馈电的介质波导裂缝阵天线。本发明提供种采用金属空心波导作为馈电装置的裂缝阵天线，相对于传统的介质波导馈电方式，本发明采用的馈电方式损耗小，同时，本发明中金属空心波导馈电装置没有采用传统的平面馈电方式，而是将馈电装置单独设置，并将其
