A transmitter supplies 100 W to a 50 lossless line that is 5.65 wavelengths long. The other end of the line is connected to an antenna with a characteristic impedance of 150 + j 25 .
(a) Use the Smith chart to find the SWR and the magnitude of the reflection coefficient.
(b) How much of the transmitter power reaches the antenna
(c) Use the Smith chart to find the best place to insert a shorted matching stub on the line. (Give the answer in wavelengths from the load.)
(d) Use the Smith chart to find the proper length for the stub (in wavelengths).
