Antennas on Silicon: Hybrid integration versus SoC solutions?

Silicon technologies are now competitive with III-V components for applications in the millimeter wave frequencies range, as already demonstrated through fully integrated on-chip systems [1]-[6]. We discuss in this paper of the different thinkable alternative solutions to fully implement efficient antennas within Silicon environment, exploiting either SoC (System on Chip) or SiP (System in Package) approaches depending on the expected performances.
