MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541132800 A) filed by Sri Manakula Vinayagar Engineering College, Puducherry, India, on Dec. 29, 2025, for 'reconfigurable bandnotch filter for cognitive radio in defense electroveil.'
Inventor(s) include Dr. P. Raja; Dr. N. Saranya; S. Mohanram; and Dr. R. Kalaiyarasan.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "This invention relates to the reconfigurable bandnotch filter for cognitive radio in defense electroveil. It typically includes a FR-4 dielectric substrate (1), a microstrip transmission line (2), a split ring resonator (3), a varactor diode (4), a de biasing network (5), an inductor (6), a DC blocking capacitor (7), a SMA connector (8), a copper ground plane (9), and a solder and interconnects (10). provides dynamic, realtime interference rejection and enhanced spectrum resilience, allowing defence communication systems to autonomously "veil" or block jamming signals while maintaining secure, high-clarity connectivity in contested environments. This invention is primarily applied in tactical cognitive radio networks and electronic warfare suites to enable autonomous spectrum sensing and the dynamic suppression of high-power jamming or interference signals within contested defence environments."
