MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511126790 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 15, 2025, for 'defected ground based ultra wideband armsa for ku-band applications.'
Inventor(s) include Mr. Sayam Gupta; and Dr. Vivek Arya.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses a compact annular ring microstrip antenna integrated with a plus-shaped Defected Ground Structure (DGS) for high-performance Ku-band operation. The antenna comprises two concentric annular rings with ten embedded rectangular slots fabricated on an FR4 substrate to enhance electromagnetic coupling and radiation efficiency. The DGS suppresses surface waves, improves impedance matching, and broadens the operational bandwidth without the need for multilayer structures or external matching circuits. Simulations performed using ANSYS HFSS confirm an impedance bandwidth of 4.29 GHz, a peak gain of 8.11 dB, and a return loss of -18.63 dB within the 13.04-17.33 GHz frequency range. The antenna exhibits stable radiation patterns and low VSWR, making it suitable for satellite communication, radar applications, UAVs, CubeSats, and high-frequency wireless systems. The invention provides a compact, low-cost, and fabrication-friendly antenna solution for next-generation wideband communication platforms."
