Large-Scale Phased Array Challenges: Packaging, Integration and Calibration Considerations

It is remarkable to witness the recent advancements in the field of mm-Wave and THz phased array design, primarily motivated by the promise of 5G communication networks. Both industry and research institutions have demonstrated large-scale phased arrays across a wide range of mm-wave frequencies. This workshop examines the end-to-end design challenges for large-scale mm-wave phased array systems. Architecture considerations for various reported phased arrays are considered and compared. Furthermore, limits of packaging, thermal solutions, antenna integration and material usage is examined along with high-level functions such as calibration and self-test features.
