Consider the smith chart shown below. The represents the input impedance locus, as a function of frequency, for a certain antenna. Points A, B, C, and D correspond to: An open circuit (lambda = 1 at an angle of 0 degree), a short circuit (lambda = 1 at an angle of 180 degree), a matched impedance, an inductive impedance, respectively. An inductive impedance, a matched impedance, a short circuit (lambda = 1 at an angle of 180 degree), an open circuit (lambda = 1 at an angle of 0 degree), respectively. An inductive impedance, a matched impedance, an open circuit (lambda = 1 at an angle of 0 degree), a short circuit (lambda = 1 at an angle of 180 degree), respectively. A capacitive impedance, a matched impedance, an open circuit (lambda = 1 at an angle of 0 degree), a short circuit (lambda = 1 at an angle of 180 degree), respectively.
Points A,B,C, and D corresponds to
A. An inductive impedance : Since it has impedance r+jx form. So it is inductive impedance.
B. A Mtached Impedance : It has reflection coefficient zero value. So it is matched Impedance.
C. An open circuit : At point C , we have r=x=infinite, so it is open circuit opint.
D. A short circuit : At point D, we have r=x=0 ohm, so it is short circuit point.
So option C correct answer.
