Abstract
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.
