MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202411101325 A) filed by Indian Institute Of Technology, New Delhi, on Dec. 20, 2024, for 'a system and a method for sparse array gaussian beamforming in joint sensing and communication (jsac).'
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: "An antenna system for joint sensing and communication (JSAC) integrates Gaussian beamforming with coprime fractal sparse arrays to achieve high directivity, reduced beamwidth, and low sidelobe levels. Radiating elements are positioned according to a coprime fractal geometry derived from integers M and N and driven by complex weights approximating a Gaussian amplitude taper with steerable phases. The sparse, self-similar layout expands the virtual aperture and increases the degree of freedom for MIMO source estimation with less hardware. A beamforming controller adapts taper variance and steering to environmental conditions, supports multi-beam superposition, and places adaptive nulls to mitigate interference. System embodiments include RF transceivers and baseband processors that reuse pilots for simultaneous communication and sensing, perform calibrated beam scans to generate coverage maps, and compensate mutual coupling and element errors. The approach yields measurable improvements in gain, directivity, HPBW, and SLL across sub-6 GHz and millimeter-wave bands, enabling energy-efficient, steerable pencil beams."
