  • Electromagnetic field pattern for phased array antenna
    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.
