Hi,


SBR+ is used for "electrically large" simulations. If you are designing the RFID tag then use HFSS. If you are using the RFID as a component in some environment or platform such as evaluating the tag when placed on some object and you want to see the performance within a room setting then SBR+ is appropriate. Use of HFSSIE or SBR+ can be appropriate - it all depends of your application.


Best Regards
