Show me plz! How to simulate EBG - like bandpass filter with varactor diode!

Which simulation software suitable the most? ADS, HFSS, or CST can put the varactor in microstrip BPF? Show me plz, I'm very new, thank you my friends.

Obtain parameters of diode with lumped R,L,C values for different voltages
then HFSS is ok and search EDA or read https://www.edaboard.com/thread35137.html

Hi Sunnyskyguy!
Thank you so much but I am not clear understand. Actually I am very new, can you give me a example?
