QUESTION THREE [15 marks] A telecommunication link at 100 MHz is made of two antennas; a transmitting antenna with a directivity of 1.6 dB and a receiving antenna with a directivity of 8 dB separated by a distance \( r=4.8 \mathrm{~km} \). Each antenna has an efficiency of 0.5 . If the radiated power by the transmitting antenna is 200 W , find: a) The average power density at the receiving antenna; [5 marks] b) The maximum effective area of the receiving antenna; [ 2.5 marks] c) The power received by the load connected to the receiving antenna. [5 marks] d) The free space path loss of this telecommunication link. [2.5 marks]
