MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061393 A) filed by Dr. Revansiddappa S. Kinagi; Dr. Vilaskumar M. Patil; Dr. Revati G; Dr. Mahesh R K; Dr. Gurudev Z; Dr. Jagadeesh Patil; Dr. Sanjeev Kumar J; Dr. Sharanu K; and Sharnbasva University, Gulbarga, Karnataka, on May 14, for 'tunable dual-band microstrip patch antenna for sub-6 ghz 5g applications.'
Inventor(s) include Dr. Revansiddappa S. Kinagi; Dr. Vilaskumar M. Patil; Dr. Revati G; Dr. Mahesh R K; Dr. Gurudev Z; Dr. Jagadeesh Patil; Dr. Sanjeev Kumar J; and Dr. Sharanu K.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a tunable dual-band microstrip patch antenna for Sub-6 GHz 5G communication applications. The antenna comprises a dielectric substrate (1) supporting a rectangular radiating patch (2), wherein dual-band operation is achieved through an offset feed mechanism (3). A microstrip feed line (4) coupled with a quarter-wave transformer (5) provides impedance matching and efficient signal transmission from an SMA connector (6). A ground plane (7) is provided on the opposite surface of the substrate (1) to ensure stable radiation characteristics. The invention enables excitation of multiple resonant modes within a single-layer structure, wherein a primary frequency is governed by patch length and a secondary frequency is controlled by aspect ratio and feed offset. The design allows tunable frequency ratio without using active components or multilayer configurations. The proposed antenna offers compact size, low cost, improved efficiency, and adaptability across multiple Sub-6 GHz 5G bands."
