Antennas are normally modeled with CHRONOS and SINGULA.
- Linear antennas
- Microstrip antennas
- Horn antennas
- Reflector antennas
- Dielectric resonating antennas
- Phased array antennas
- Slots in waveguide
In the case where the geometry is much smaller than the wavelength, the antenna/receiver is best thought of as inductive coupling. The simulation software to model this with are MAGNETO (2D/RS) or AMPERES (3D simulation). If there are conductors present which will affect the coupling through Eddy Currents, then use OERSTED (2D/RS) or FARADAY (3D simulation) instead.
