hello,
I am working on a reconfigurable antenna and need to insert a pin diode on it. Any technical suggestions or diagrams to help me with that, do I need to insert a capacitor before and after the diode, or just on capacitor is enough.
Thanks in advance
You just place small rectangular strips where you want to insert PIN diode.
Select the strip.
Right click on it.
Go to assign boundary.
Then chose lumped RLC and declare value of "R" when switch is "ON" and declare value of "C" when switch is "OFF".
In case of switch ON it will have some resistance.
In case of switch OFF, it will have some capacitance.
The values of R and C depends upon the different PIN diodes. They are generally given in datasheets of particular switches.
Along with this kindly follow the discussions:

Anveshkumar Nella Sir cant we directly insert lumped element ( Diode) ????

It may not be possible... Till now there is no such kind of flexibility....
