The former expert solved the question, but I didn't
understand how he simplified the fractions.
A communication satellite is in stationary (synchronous) orbit about the carch (assume
altitude of 22.300 statute miles). Its transmitter generates 8.0 W. Assume the transmit-
ting antenna is isotropic. Its signal is received by the 210-ft diameter tracking parabo-
loidal antenna on the earth at the NASA tracking station at Goldstone, California. Also
assume no resistive loss in either antenna, perfect polarization match, and perfect
impedance match at both antennas. At a frequency of 2 GHz, determine the:
(a) power density (in watts/m²) incident on the receiving antenna.
(b) power received by the ground-based antenna whose gain is 60 dB.
