MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511122590 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 5, 2025, for 'dgs based annular ring microstrip antenna for ku band applications.'
Inventor(s) include Mr. Sayam Gupta; Dr. Vivek Arya; and Dr. Rishabh Dev Shukla.
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 high-performance annular ring microstrip antenna incorporating a plus-shaped defected ground structure (DGS) for Ku band applications. The antenna comprises a stacked radiating structure with outer and inner annular rings and parasitic circular elements arranged on an FR4 substrate. A plus-shaped DGS is etched beneath the radiating patch to suppress surface waves, enhance impedance bandwidth, and improve radiation efficiency. The microstrip feed transformer ensures smooth impedance transition and efficient power transfer. The optimized structure achieves a bandwidth of 3.62 GHz, a return loss of -22.72 dB, a gain of 7.85 dB, and a VSWR of 1.27. Simulations conducted using ANSYS HFSS confirm stable radiation patterns, high directivity, and improved electromagnetic performance compared with conventional annular ring antennas. The invention provides a low-cost, compact, and scalable antenna suitable for satellite communication, radar systems, UAVs, and high-frequency wireless communication modules operating in the Ku band."
