I have 50mV in the function generator with 10kHz. Does the connection and reading seem about right? I need to read output voltage.
The solution sent previously is incorrect; I need
the correct solution.
An antenna with a radiation impedance of 75+j10 ohm, with 10 ohm loss resistance, is
connected to a generator with open-circuit voltage of 12 v and an internal impedance of 20 ohms via
a 2/4-long transmission line with characteristic impedance of 75 ohms.
(a) Draw the equivalent circuit
(c) Determine the power radiated by the antenna.
