Antenna-IC Interfaces for Scalable mm-Wave Arrays for 5G and Beyond-5G Applications
Achieving a wideband, efficient, scalable and low-cost interface between IC and antennas is critical for mm-wave transceivers in silicon. This talk will summarize development of scalable phased arrays from an IC perspective and present challenges related to the IC and antenna interface in large-scale arrays. Critical needs for Antenna-in-package, Co-integrated antennas and Antenna-on-Chip will be described in the context of applications as well as in terms of integration and scalability to set the stage for subsequent workshop presentations on state-of-the-art techniques in these areas. An antenna co-integration approach that achieves dual-polarization transmission and reception using on-chip dual-pol feeds will also be presented to demonstrate feasibility of wafer-scale antenna interfaces at mm-wave.
