Appendix A: Hints for Simulations in Ansys HFSS
Ansys HFSS is industry standard software that is very popular for full-wave electromagnetic simulations. Simulations for lower frequency antennas below 10 GHz are straightforward, with no need for special consideration. But when designing mmWave antennas beyond 25 GHz, several aspects of simulations have to be examined. This section deals with hints for the simulation of Ka band antennas for 5G applications.
A.1Modelling
Care must be taken to use only lossy dielectrics and the actual conductor to be used. For example, copper of finite thickness is recommended rather than a perfect electric conductor (PEC) with no thickness. The dielectric loss tangent and conductor losses would ...
