Hello , i have tried to simulate a halfwave microstrip by this example.
the end of the microstrip is open circuit.
the substrate height and width are tested for 50ohm as shown bellow.

but when i simulate this transmitiion line i get the impedance going around the open circuit circumference on the right side as you can see on the smith chart bellow..
how do i match this transmition line to 50 ohms?
is there a way?
thanks.
