In a communication system an antenna is connected through a 50 Q transmission line. The antenna's input impedance is 60 + j 70 Q, and radiation efficiency is 90 %. If the 50 Q transmitter can deliver 20 W when connected to a 50 Q load, calculate the power delivered to the antenna and power radiated by the antenna. Also, calculate the power density at a distance of 2 km from the transmitting antenna if the antenna's gain is 20 dB.
