How Chips Are Using On-Chip Antennas for Wireless Interconnects

Episode 98 of The Hardware Podcast explores the latest in on-chip antennas for wireless interconnects—a technology that replaces traditional wired buses with millimeter-wave radio links inside a package. Lucas and Luna discuss how companies like Intel and Samsung are integrating tiny antennas onto silicon to reduce latency and power in multi-chip systems, with specific data on the 60 GHz band achieving 20 Gbps per link. They break down the engineering trade-offs: antenna efficiency versus chip area, and the challenge of interference in dense arrays. The episode also touches on a startup applying this to AI accelerators for modular scaling. A concrete example from a recent ISSCC paper shows a 4×4 antenna array delivering 50% lower power than wired SerDes. #OnChipAntennas #WirelessInterconnects #MillimeterWave #ChipDesign #Semiconductors #Intel #Samsung #ISSCC #AIAccelerators #MultiChipModules #60GHz #AntennaArray #SerDes #LowPower #HardwareEngineering #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
