  • Publication number: 20250015909
    Abstract: A computing system including a processor configured to receive a mesh of a three-dimensional geometry. The processor is further configured to receive a source antenna location and a destination antenna location on the mesh. The processor is further configured to compute a ray path as an estimated shortest path between the source antenna location and the destination antenna location. The ray path includes a geodesic path over the mesh and a free space path outside the mesh. The ray path is computed at least in part by computing the geodesic path at least in part by performing inferencing at a trained neural network. Computing the ray path further includes computing the free space path at least in part by performing raytracing from a launch point located at an endpoint of the geodesic path. The processor is further configured to output the ray path to an additional computing process.

  • Patent number: 10656234
    Abstract: A method includes determining, on an individual element-by-element basis, a normalized far-field pattern for each radiating element of a plurality of antenna elements. The plurality of antenna elements is associated with a phased array antenna. The method also includes determining an overall electromagnetic far-field pattern for the phased array antenna based on individual normalized element far-field patterns and based on beamforming parameters associated with a location of interest. The overall electromagnetic far-field pattern is usable to determine a signal strength, at the location of interest, of a signal transmitted from the phased array antenna. The method also includes determining an isolation between the phased array antenna and a secondary communication device based on the overall electromagnetic far-field pattern. The method further includes generating an output indicative of the isolation.
