Substrate integrated waveguide horn antenna array and wireless communication equipment

The invention discloses a substrate integrated waveguide horn antenna array and wireless communication equipment, and the substrate integrated waveguide horn antenna array comprises three layers of dielectric substrates, a plurality of H-plane horn antenna units of the same substrate integrated waveguide are arranged on the middle layer dielectric substrate side by side, and two sections of trapezoids are excavated from the interior of each horn antenna unit to form a stepped horn-shaped medium. Dipole arrays and rectangular patches are arranged at the positions, corresponding to the loudspeaker aperture, of the upper dielectric substrate and the lower dielectric substrate, and metal through hole arrays and rectangular patch arrays are arranged at the rear ends of the dipole arrays. According to the invention, a good broadband characteristic is realized under a low-thickness substrate; the miniaturization of the horn antenna is realized by reducing the longitudinal length of the horn; through digging out a st
