tunable antenna

Dear All,

I really need some help

I am designing 2 patches antenna to operat in different bands, i have to conect them through switch in order to control the resonant frequency.

Can any one help me on how to design switch in HFSS sofware please.

if there is any design in hfss it would be very very helpful

Thank you all

Probably you can do this way as switch or any active circuit can not be simulated by 3D solver.

Have a 2 test method
1) have the antenna patterns which are open
2) place a short ( ideally it should be the same as switch contribution) where you would like to place the switch
This will give you procedure to validate the antenna
The question is where you would like to place the switch. Is it on low Current density or High?
