hi, I am working on RFID tag antennas which are meander line half wave dipole antennas for 866Mhz-960Mhz. I am a bit confuse about using either PML boundry or radiation boundry for simulation that can be more closer to real results. Any suggestions
 

If you want really good results close to actual results, then you have to use PML boundary instead of Radiation boundary. The advantages of PML are you get good results. But the trade-off is, it really takes a lot of time for simulation. And have to assign some thickness for a PML boundary.Using radiation box, you can get a quick view of your results (less time for simulation), though not accurate results.
