MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202411101333 A) filed by Indian Institute Of Technology, New Delhi, on Dec. 20, 2024, for 'advanced sparse fractal arrays with maximized degree of freedom for 5g laptops.'
Inventor(s) include Aggarwal, Monika; Goel, Kretika; and Kar, Subrat.
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: "A 5G-enabled laptop employing an 8 8 MIMO antenna system is disclosed. Radiating elements are arranged as a sparse fractal array formed by the cross-sum of two sub-arrays S1 and S2 with spacings d1 and d2 satisfying d2 = (2M + 1)d1, producing sensor positions S = S1 ? S2. The configuration leverages a virtual array via a difference coarray to extend the effective aperture and increase the degree of freedom, enabling estimation of more sources than physical antennas using subspace algorithms such as MUSIC. Augmented nested configurations with normalized sensor locations achieve contiguous coarray spans (e.g., -11 to +11 and -14 to +14), supporting estimation of at least eleven and fourteen sources, respectively, with eight antennas. Strategic placement along edges, hinges, and chassis reduces mutual interference and enhances spatial diversity. The system improves beamforming, throughput, coverage, and latency for 5G laptops while accommodating thin form factors and multi-band operation."
