Embodiment
[0031] The hybrid feeding slot array antenna of the present invention works in the Ka band, mainly including 40 substrate integrated waveguides, 220 radiation slots, 40 coupling feeding slots, power division and difference network, antenna and beam port, antenna difference beam port.
[0032] refer to figure 1 and figure 2 , the radiation front is a double-sided copper-clad printed board, using a substrate-integrated waveguide structure, a dielectric substrate 1, a metal layer 2 on the front side of the dielectric substrate, a metal layer 3 on the back side of the dielectric substrate, and a metallized through-hole array 4 penetrating the dielectric substrate. Multiple substrate integrated waveguides. The dielectric board is Rogers 5880, with a relative dielectric constant of 2.2 and a thickness of 0.787mm. The thickness of the upper and lower metal layers is 0.035mm. The diameter of the metallized through hole is 0.5mm, and the distance between adjacent through holes is 1m...
