Hi all!
I have to do an exercize for university. the goal is to match a line with a double stub with ansoft designer.
the problem is how to rotate 90° the g=1 circonference on the smith chart.
I think that i have to add a piece of line λ/8 long. but what's the component that rappresents this piece of line in the circuit design?
thanks and sorry for my english
