Air-Filled Slot for Antenna-in-Package Solutions
3DGS delivers ultra-low-loss glass substrate for antenna-in-package (AiP) solutions using patented air-filled cavity manufacturing proesss. Our platform enables 5G mmWave antenna arrays and transmission-line based structures with superior performance compared to conventional organic and ceramic packaging, eliminating the path loss and signal degradation inherent in traditional dielectric materials.
Overview
3DGS provides the ideal platform for integrating RF transceivers and antenna arrays on a single substrate with glass core antenna-in-package (AiP) solutions. Our patented air-cavity manufacturing process eliminates dielectric loss at mmWave frequencies 3DGS and Nokia Bell Labs have teamed together to create a novel 64-element air-filled slot antenna array operating from 77 to 81 GHz; however, the technology is scalable for frequencies up to 200 GHz.
In collaboration with Nokia Bell Labs, 3DGS developed a 64-element air-filled slot antenna array operating from 77 to 81 GHz for automotive radar and 5G base station applications. The platform scales to 200 GHz, supporting emerging 6G networks and sub-THz communication systems.
Our air-filled substrate integrated waveguide (SIW) architecture achieves an effective dielectric constant near 1.0 —the theoretical minimum for low insertion loss and maximum signal integrity. Micron-scale precision manufacturing ensures high repeatability and excellent return loss, making the glass for antenna-in-package (AiP) ideal for high-volume 5G infrastructure and automotive deployment.
