MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541115038 A) filed by Dr T Annalakshmi; Dr S Sathya; and S. A. Engineering College, Chennai, Tamil Nadu, on Nov. 21, 2025, for 'performance and analysis of uwb aesthetic pattern textile antenna for wban applications.'
Inventor(s) include Dr T Annalakshmi; and Dr S Sathya.
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 article proposes a new aesthetic pattern- three three-petal flower patch antenna that operates at Ultra-Wide Band (UWB) for Wireless Body Area Network (WBAN) applications. The flower structure consists of three petals and a center circle patch with the partial ground plane at the bottom. A double-sided copper- coated conductive fabric, which is 0.08 mm thick, having a surface resistivity of 0.05 Q/square, serves as the antenna patch and ground material. This conductive patch is placed in a denim jeans material with 1mm thick that forms the substrate. The utilization of a two-layer substrate and partial ground method enhances the impedance bandwidth of the antenna. The size of the antenna is 60 mm x 60 mm * 2.16 mm. The reflection coefficient, gain, efficiency, radiation pattern, and effects of bending were the various parameters analyzed for the flower antenna. The antenna radiates from 3 to 12 GHz, which covers the entire UWB frequency range from 3.1 to 10.6 GHz assigned by Federal Communications Commission (FCC). The measurement results validate the performance of a flower patch antenna."
