You have an antenna with an input impedance of Z (140 -j35)2 at f 120 MHz. You would like to match this load to a 70Ω transmission line using a single stub tuner (vp-2.2x108 m/s). Using the Smith chart, determine the distance d away from the load and the length l of a short-circuited parallel stub to accomplish the matching goal at the design frequency. Estimate the reduction in radiated power if the operating frequency is changed to f 125...
