reconfigurable antenna using hfss

hey,i m supposed to design a reconfigurable antenna using hfss. I have designed a microstrip antenna, now how can i make it reconfigurable?help!

This is the wrong approach. A reconfigurable antenna is designed to be reconfigurable.

Hello!!
I think you need to figure out what does the reconfigurable antenna mean.
Those kinds of antenna in controllable smartly where they could change the resonant frequency, the gain, the band width or the polarization when it must be, we best say they react with the work environment.
I just think like that and may be I am wrong
