Line properties using the Smith chart. A long line with characteristic impedance Z0 = 100 Ω operates at 1 GHz. The speed of propagation on the line is c and load impedance is 260 + jI80 Ω. Find:
(a) The reflection coefficient at the load.
(b) The reflection coefficient at a distance of 20 m from the load toward the generator.
(c) Standing wave ratio.
(d) Input impedance at 20 m from the load.
(e) Location of the first voltage maximum and first voltage minimum from the load.
