Cutting-Edge Antenna Technology Solutions

NVIDIA unveiled partnerships with industry leaders on the research and development of AI-native 6G wireless network. Next-gen wireless networks must be integrated with AI to seamlessly connect hundreds of billions of phones, sensors, cameras, robots and autonomous vehicles. While the integration of AI for intelligent 6G networks and the use of THz frequencies offers unprecedented data rates, it is the advancements in antenna design that will unlock these capabilities. Operating in THz spectrum presents unique challenges that demand innovative antenna solutions. The short wavelengths necessitate highly miniaturized antennas, yet these must deliver substantial directional gain to overcome the significant path loss and atmospheric absorption characteristic of THz propagation. Phased arrays emerge as a prime solution for achieving the necessary high directivity. Their ability for electronic beam steering is crucial for overcoming potential blockages and serving multiple users. However, THz communication necessitate using true-time delays rather than just phase shifters to avoid beam squint. Beam sweeping methods might be too slow. On-Chip Antennas: The reduced wavelength allows direct integration of antennas within ICs. However, challenges include losses at the die and package level. Antennas in Package: Integrating antennas into PCBs offers a cost-effective and flexible alternative. However, challenges include losses at the chip-to-PCB interface, high material losses and manufacturing precision. Micro-Machined Waveguide Antennas: These antennas are known for their excellent performance, but their integration with ICs poses challenges in achieving consistent impedance matching. Reconfigurable Intelligent Surfaces (RIS): these are two-dimensional reflecting surfaces for RF energy composed of individual array elements that can be dynamically reconfigured to change the parameters of the RF path. Think of an RIS as a flexible, software-controlled mirror placed in the channel between the transmitter and receiver. While the development of RIS for THz frequencies faces the challenge of lacking switches that function effectively at these frequencies, advancements in metasurfaces are showing promise. A RIS can change the channel itself to improve performance, increase SNR, and reduce BER. The ability of an RIS to control the reflection, refraction, scattering, and diffraction of RF energy by adjusting the phase and amplitude response of its elements makes it a powerful tool for dynamic beam shaping and control in 6G communication. While the promise of 6G with AI and THz communication is tantalizing, breakthroughs in antenna technology are indispensable for realizing its full potential.

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable garment -- a sweater or a blanket that is ultralight, portable, easy to fold up and stow away. Not having to use heavy, bulky satellite antennas would make communications much easier for those who live or travel in remote locations -- a lightweight, flexible antenna that can send information over long distances would be a useful tool for both the public and private sectors. A Columbia Engineering team reports that they have used their expertise in metasurfaces -- ultra-thin optical components that can control the propagation of light -- and a low-cost, highly scalable flat-knitting platform to create radio-frequency (RF) communications antennas that are easy to carry and deploy. The study, led by Nanfang Yu, associate professor of applied physics and applied mathematics, was published in Advanced Materials. https://lnkd.in/gw56dUxF #columbiaengineering #appliedphysics #knitting
