  • Patent number: 11329362
    Abstract: On-chip wireless links offer improved network performance due to long distance communication, additional bandwidth, and broadcasting capabilities of antennas. A Through-Silicon Via (TSV)-based antenna design called TSV_A establishes multi-band wireless communication through the silicon substrate medium with only a 3 dB loss over a 30 mm on-chip distance. Simulation results show an improvement in network latency up to ˜13% (average improvement of ˜7%), energy-delay improvements of ˜34% on average, and an improvement in throughput up to ˜34% (average improvement).
