3.7 A DBS-TV geostationary satellite provides communications within Western Europe at Ku band. The antennas on the satellite have beamwidths of 3° in the E-W direction and 1.5° in the N-S direction. The downlink antenna on the satel- lite used for broadcasting TV signals operates at a center frequency of 12.25 GHz. The uplink to the satellite operates at 17.5 GHz with a separate satellite antenna. a. Estimate the gain of the transmitting antenna. Find its dimensions in the N-S and E-W directions. b. Estimate the gain of the receiving antenna. Find its dimensions in the N-S and E-W directions.
