Wireless Network-on-Chips (WNoCs) leverage Terahertz (THz) waves for efficient intra-chip communication, overcoming limitations of traditional wired networks. Simulations show zigzag antennas offer superior performance for these high-frequency chip-to-chip links.
Area of Science:
- Electrical Engineering and Computer Science
- Electromagnetics and Communications
Background:
- Increasing demand for computing power challenges traditional multi-core processor scaling.
- Wired networks face limitations in bandwidth and power consumption for on-chip communication.
- System-on-Chip (SoC) integration requires advanced communication solutions.
Purpose of the Study:
- To explore Wireless Network-on-Chips (WNoCs) utilizing Terahertz (THz) waves for intra- and inter-chip communication.
- To investigate the feasibility and performance of THz antennas within a chip environment.
- To analyze electromagnetic field behavior and link budget for WNoC systems.
Main Methods:
- Utilized Ansys High Frequency Structure Simulator (HFSS) for full-wave electromagnetic field analysis.
- Simulated dipole and zigzag antennas for THz wave communication at chip-level.
- Performed transmission coefficient characterization, path loss analysis, and electric field distribution studies.
Main Results:
- Achieved resonant frequencies of 446 GHz and 462.5 GHz with transmission coefficients of -28 dB and -33 to -41 dB.
- Validated transmission power feasibility, ensuring energy expenditure below 1 pJ/bit.
- Zigzag antennas demonstrated higher electric field magnitude compared to dipole antennas for intra-chip communication.
Conclusions:
- WNoCs using THz waves are a viable solution for high-performance intra-chip communication.
- Antenna design significantly impacts signal propagation and efficiency, with zigzag antennas showing promise.
- Transmission relies on ground plane reflection, a phenomenon confirmed by electric field distribution analysis.

Design Example
Semiconductors
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...
