MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202631096925 A) filed by Indian Institute Of Technology Indian School Of Mines Dhanbad on August 11, 2026, for A Compact Dual Band Wearable Antenna With Polarization Diversity Characteristics.
Inventors include Sahu, Nibash Kumar; and Gangwar, Ravi Kumar.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: A dual-band wearable antenna is described. The dual-band wearable antenna comprising: a dual-band dual-polarized monopole radiator (102) configured to: generate a first radiated electromagnetic wave in a lower millimeter-wave band with linear polarization and omnidirectional radiation characteristics, and a second radiated electromagnetic wave in a higher millimeter-wave band with circular polarization and dual-beam radiation characteristics; a metasurface (104) comprising a plurality of polarization-converting unit cells arranged in a two-dimensional array and disposed beneath the monopole radiator, each polarization-converting unit cell comprising: a double-layer dielectric configuration; an upper patch configured to initiate polarization-converting behavior; and a lower patch rotated relative to the upper patch to extend the polarization-converting behavior over a higher-frequency range.
