Homework Answers
A. Antenna radiation requirements.
The primary reason for using high frequency carrier waves for sending information through EM waves is because it allows smaller antenna design. Typically, antenna length is given by L = wavelength/4
If carrier wave is not used, then for sending audio frequency of
say 30 Hz, you will get quarter-wave antenna length of:
L =
c/(4?f)=3?108/(4?30)=2.25?109metersc/(4?f)=3?108/(4?30)=2.25?109meters
A high frequency carrier would significantly reduce the antenna length.
