Structure for distributing radio frequency signals

A structure comprising a first face with a plurality of first apertures configured to interface with at least one first external RF circuitry for processing RF signals and a second face with a plurality of second apertures configured to transmit and/or receive RF signals, the plurality of first apertures are connected to the second apertures via through-holes embedded in the structure and having an electrically conducting inner wall and configured to form a waveguide medium for carrying radio frequency, RF, signals between the plurality of first apertures and the plurality of second apertures,

• wherein the first face is dimensioned to accommodate the at least one first external RF circuitry, the at least one first external RF circuitry is an integrated circuit, and
• wherein the first apertures are spaced apart according to interconnect requirements of integrated circuits, and the second apertures are spaced apart according to radiating requirements related to the frequency of the RF signals.
