An interconnect is described that comprises an interconnect channel, and two channel couplers coupled to the two ends of the interconnect channel through respective stoppers that provide a gap between the channel couplers and the interconnect channel. Each channel coupler can comprise a coplanar waveguide, a microstrip line, and a patch-antenna based coupler. The interconnect can enable communication between integrated circuits using signal waves having a frequency between 100 GHz and 3 THz.
