Q. A transmitter is connected to an antenna by a transmission line for which ¯ Z0 = R0 = 50 . The transmitter source impedance is matched tothe line, but the antenna is known to be unmatched and has a re?ection coef?cient
where RL (= ¯ ZL) is the load impedance. The transmitter produces a power of 15 kWin the incidentwave to the antenna andwill be destroyed due to overheat if the re?ected wave's power exceeds 2 kW. Determine the antenna's radiated power in this case and comment on whether the transmitter will survive.
