(a) Some antennas have a physical aperture area A that can be identified and is related to the effective area Ae by Ae = ρaA, where ρa is known as the aperture efficiency. For a circular-aperture antenna with a diameter of 2 m and an aperture efficiency of 0.5 at 4 GHz, calculate the power gain.
(b) Referring to Figure, let two such antennas be used for transmitting and receiving, while the two stations are separated by 50 km. Let the total loss over the link be 9 dB, while the transmitter generates 0.5 W. Find the available received power.
