Delaware Patent of the Month – September 2024
Phase Sensitive Innovations, Inc. (PSI), a photonic device technology firm, has pioneered a novel antenna array system that integrates optical and radio frequency (RF) technologies to significantly enhance high-frequency communications and sensing. The system is built on a multi-layered substrate, featuring photodiodes and antennas designed to convert optical signals into RF outputs with high precision. This innovative approach not only increases the efficiency of signal transmission but also allows for a compact and scalable design.
A key feature of this antenna array is its ability to leverage micro-bends—tiny structures embedded in the substrate layers—that redirect optical signals from waveguides to the photodiodes. These photodiodes then generate RF currents, powering the corresponding antennas. This optical-to-RF conversion system is highly adaptable, offering potential applications in radar systems, data transmission, and even imaging technologies. By eliminating bulky transformers typically used in RF systems, this design achieves a streamlined form factor, perfect for use in space-constrained environments.
The system’s low profile and ability to conform to non-planar surfaces open up a range of possibilities for integration into both terrestrial and airborne systems. Whether used for multi-channel RF generation or high-precision radar, this invention pushes the boundaries of what’s possible in phased array systems.
With this breakthrough, PSI is transforming high-density communication technologies, offering enhanced performance, reduced power consumption, and lower production costs—making it a standout solution in the fast-evolving landscape of wireless communications and RF sensing.
