Bandwidth-enhanced full-fabric half-mode substrate integrated cavity antenna

The utility model discloses a bandwidth-enhanced full-fabric half-mode substrate integrated cavity antenna, which comprises an antenna body, a top surface, a bottom surface and two dielectric substrates, the top surface and the bottom surface are conductive, and the two dielectric substrates are stacked between the top surface and the bottom surface. And the feed structure comprises a feed line and a feed metal column, the feed line is located between the two dielectric substrates, the movable end of the feed line extends to the outer side of the antenna body, and the feed metal column is connected between the top surface and the feed line. According to the utility model, a feed structure is introduced on the basis of a substrate integrated waveguide (SIW) antenna, the feed structure is composed of a strip-shaped feed line, a feed metal column and an SMA connector, the feed structure is a planar feed structure, and compared with a vertical feed structure, the planar feed structure is easier to integrate with
