Latest Patents

Among his notable inventions, two of his latest patents stand out for their ingenuity and complexity. The first patent, titled "Active-array multi-beam antenna comprising a hybrid device for forming directive beams," describes an active-array multi-beam antenna that incorporates radiating elements and a hybrid device designed to form directive beams. This hybrid apparatus features an analogue stage with multiple beam-forming networks that create regional beams, alongside a digital stage for generating directive beams from these regional formations. The design includes two sub-arrays of radiating elements, which partially overlap to enhance the antenna's functionality.

His second recent patent, "Antenna integrating delay lenses in the interior of a distributor based on parallel-plate waveguide dividers," details a quasi-optical beamformer that uses a power distributor made of parallel-plate dividers. These dividers extend across various stages to manage signal distribution effectively. A unique aspect of this invention is its implementation of lenses that apply a continuously variable delay along the X-axis, thus optimizing the performance of the antenna system.
