12. (a) A parabolic antenna with a diameter of 0.75 meters is used to receive a 12 GHz satellite signal. Calculate the gain in decibels of this antenna. Assume that the antenna efficiency is 60 percent. (b) If the system noise temperature of a satellite receiver is 300 K, what is the required received sig- nal strength to produce a C/No of 80 dB? (c) If a satellite is 40,000 km from the antenna of (a), what satellite EIRP will produce a signal strength of -110dBm at the antenna terminals? Assume that the transmission frequency is 12 GHz.
