This work deals with an innovative architecture of a phased antenna array operating in the Ka band. It envisages the adoption of custom designed PA together with 64 hollow metallic horns as radiating elements. The proposed architecture is designed to work in the 25.5 to 27 GHz frequency span with a target EIRP higher than 70 dBm, even considering the maximum beam steering configuration of ±20°. The proposed concept highlights the flexibility in targeting different power levels, antenna gain and steering capabilities to finally address a large number of use-cases. The exploitation of non-uniform array is also taken into account to prevent grating lobes and increasing the steering capabilities of the phased array.
