Inkbit Technology Advantages
Better Precision, Higher Gain
Inkbit’s gradient-index (GRIN) components enhance signal gain or reduce transmission power, while suppressing side lobes. Printed directly in high-precision dielectric materials, these lenses maximize wave energy focus for next-gen wireless systems.
Ultra-Wideband Performance
Our dielectric structures exhibit low-loss, broadband behavior from sub-6 GHz to 90 GHz. This allows for multi-band functionality in a single component without the need for redesign. Engineers can streamline system complexity while supporting mmWave, and emerging 6G applications.
Minimized Beam Degradation
Traditional beamformers lose effectiveness as scan angles increase. GRIN lenses produced using our VCJ technology preserve beam fidelity and gain across wide scan angles, ideal for adjustable wireless systems.
Broader Field-of-View
Our innovative lenses expand the effective field-of-view of phased arrays and fixed-feed systems, enabling better coverage without increasing hardware complexity – ideal for mmWave sensing, satcom, and radar.
Leaner SWaP-C
By consolidating multiple components into a single printed structure using lightweight, low-loss materials, Inkbit helps deliver leaner, more efficient wireless platforms optimized for performance.
An Introduction to GRIN Lenses
What Are GRIN Lenses?
GRIN (Gradient Index) lenses are advanced dielectric components designed to steer electromagnetic waves – similar to how traditional lenses bend light, but at microwave and mmWave frequencies. Unlike conventional lenses with a fixed refractive index, GRIN lenses feature a gradually changing refractive index throughout the lens body.
Benefits of Inkbit GRIN Lenses:
- Superior beam shaping and focusing
- Wider field of view and multi-band compatibility
- Reduced size, weight, and power consumption (SWaP)
With Inkbit’s COT low-loss materials and Vision-Controlled Jetting™ (VCJ) technology, engineers can design and print complex GRIN lenses, while having access to cost effective rapid iteration cycles – with a platform that can scale end-use production and make changes as needed from a design standpoin.
Traditional Roadblocks Eliminated
Historically, GRIN lenses were difficult to manufacture, requiring multi-step machining or discrete stacking, and were limited by cost and material constraints. Our additive manufacturing systems and platform delivers GRIN lenses that are:
- Lightweight
- Broadband-capable
- Ready for production
- Fully customizable in geometry and dielectric gradient
Whether you’re developing for 5G/6G infrastructure, aerospace systems, or defense platforms, our technology gives you the fastest path from concept to fully functional, field-ready hardware.
