Antennas

• 
  ANSim is a moment method electromagnetic modeling program used mainly for antenna design. The thin-wire code is based on the high-accuracy multi-radius bridge current (MBC) method developed by Dr. Mark Tilston. Having 30-years of development, ANSim can model electrically small and medium size structures made of wires, plates, and dielectric blocks. It is the main design tool used by Phoenix Antenna Systems in Perth, Ontario, Canada. Evaluation version 1.03 and GUI are [free downloads]
