MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541085044 A) filed by IIITB COMET Foundation, Bangalore, Karnataka, on Sept. 8, 2025, for 'reconfigurable intelligent surface unit cell with integrated biasing and pin-diode loaded quad split ring resonator.'
Inventor(s) include Ankit Chandachoriya; Ravi Panwar; and Arzad Alam Kherani.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "Disclosed is a reconfigurable intelligent surface (RIS) unit cell that utilizes a quad-split ring circular resonator structure, integrated with PIN diodes to enable dynamic phase modulation. The unit cell operates efficiently at a center frequency of 5.2 GHz and provides phase shifts at other frequencies, including 3.6 GHz, 7.6 GHz, and 7.7 GHz. The device achieves 180 phase shifts and a maximum phase difference of 295 at 4.2 GHz. The DC biasing mechanism, implemented through vias in the ROGERS RT5880 dielectric substrate, eliminates the need for external circuitry, simplifying the design and reducing fabrication complexity. This RIS unit cell supports broadband operation across a frequency range of 2.0 GHz to 8.0 GHz and is suitable for applications in smart wireless communication systems, beamforming, and Internet of Things (IoT). The compact and scalable nature of the design allows for deployment in diverse smart environments."
