G-Band (175-300 GHz)

Upper Sub-Terahertz and Terahertz Transition Spectrum

Ultra-high frequency spectrum operating near the true terahertz boundary, enabling micro-scale antennas and extreme-density short-range links.

Technical Explanation

Spanning from 175 to 300 GHz, the G-Band approaches the far-infrared region where millimeter-wave radio transitions into quasi-optical propagation. At these frequencies, antenna wavelengths are under 1 millimeter, allowing thousands of radiating elements to fit inside a postage-stamp-sized form factor. The G-band is targeted for chip-to-chip wireless interconnects, ultra-high-precision radar imaging (<1 mm resolution), and short-range terabit data transfers.

Key Functions

  • Enables extreme antenna array miniaturization with sub-millimeter element spacing
  • Provides massive spectral bandwidths capable of multi-hundred-gigabit throughput
  • Delivers millimeter-grade spatial resolution for industrial non-destructive testing
  • Supports wireless backplane and inter-chip data interconnects in supercomputers
