Episode Why Chips Are Using On-Chip Antennas for Wireless Interconnects
In this episode of The Hardware Podcast, Lucas and Luna explore the emerging trend of integrating antennas directly onto silicon chips to replace traditional wired interconnects for short-range data communication. They discuss a 2025 paper from Intel Labs demonstrating a 60GHz on-chip antenna array achieving 40 Gbps data rates over a few millimeters, the engineering challenges of antenna efficiency in silicon, and how this technology could reshape chip-to-chip communication in data centers and multi-chip modules. The conversation also covers comparisons with existing solutions like TSV and optical interconnects, and the potential for wireless interconnects to reduce latency and power consumption in dense compute clusters. Tune in for a detailed look at a cutting-edge hardware innovation that may soon become standard in high-performance computing.
