3- A radio link operating at $$10\mathrm{GHz}$$ is upgraded to $$20\mathrm{GHz}$$ without changing the antenna. If by this upgrade the transmitted power drops by a factor of 2 , how much will the received signal power be affected? Assume the antennas are horn antennas, which can support both frequencies. After the change in frequency, will the received power be more or less? By how much will it be more or less?
