Satellite Communication

Q1: Which one of the following statement is correct?

A Satellite spacing is not affected by the bandwidth of the transmitting earth station

B Beamwidth is independent of antenna size and frequency band used

C The width of a beam in space is inversely proportional to the width of the transmitting antenna

D Use of high-frequency bands permits less number of satellites to share the orbit

ANS:C - The width of a beam in space is inversely proportional to the width of the transmitting antenna

A is not the answer since satellite spacing is directly related to the bandwidth.

C is correct since if the width, if the antenna increases its directivity, increases thus giving a more tapered wave, thus beamwidth decreases.
