Beta 0.4 version of VirAntenn software has been released and is available to interested parties for testing and evaluation subject to ITAR restrictions. The software was funded by U.S. Navy under a SBIR Phase II contract and Beta version is the Phase II deliverable to the government. VirAntenn offers a fully-functional 3D GUI for geometry capture and simulation for modeling complex 3D antennas, large finite array of such antennas and the prediction of the antenna pattern when mounted on an aircraft, ship or ground vehicle. Software is equipped with the advanced full-wave and asymptotic modeling engines provided by the Ohio State University and Applied EM, Inc., respectively.
