The present disclosure provides an array antenna. The array antenna includes a cavity power divider that receives an input signal and performs power division to output a first power-divided signal. The array antenna also includes a final-stage power dividing, coupling, and radiating unit that includes a dielectric substrate and a first and a second metal surface layer. A coupling slot array is formed on the second metal surface layer to receive the first power-divided signal. A radiating slot array corresponding to the coupling slot array is formed on the first metal surface layer; Several plated through-hole units are provided on the dielectric substrate, where the plated through-hole units go through the first and second metal surface layers vertically, and a range corresponding to each plated through-hole unit encloses a coupling slot and a radiating slot corresponding to the coupling slot.

The invention relates to a surface mount microwave system, comprising a multilayer arrangement comprising a first conductive layer, a second conductive layer and a dielectric layer, wherein the first conductive layer is arranged on the dielectric layer, and wherein the dielectric layer is arranged on the second conductive layer, wherein the first conductive layer comprises a microwave circuit and wherein the second conductive layer forms a reference potential layer, a hollow microwave waveguide being at least partly formed in the second conductive layer, and a microwave transition structure for electromagnetically coupling the first conductive layer with the hollow microwave waveguide. According to some implementation forms, a reflector on a cover covering the multilayer arrangement may be avoided.
