hi all,i see that topic is repeated so much here,who trust with his simulator,i see some papers simulate with cst but not agree with measured,but most of fdtd siumlators has very approximately results agree with measured but fdtd is very slow compare with cst why?.i trust by cst but results simulation not accurate as measured .
regards
Hi,
I think it's better for you to work with ADS layout, at first.
after that you can use HFSS to get more accurate results. (based on Finite Element Method)
But Microwave Studio is also another good option.
Good Luck.
