20 dB Horn Antenna

Simulation time and requirements for EM computation of horn antenna are minimal and listed in the table below. Results are presented for radiation pattern, currents on antenna and near field. It is also demonstrated that requirements are reduced by applying one or two symmetry planes (models marked as half and quarter, respectively).
