As communication engineer you have been requested to design radio communication system using parabolic antenna of 120 cm diameter operates on 1800 MHz frequency with input power of 1 KW, radiated power of 62-W and radiation resistance is 18.75Ω. Obtain:
i. Efficiency of the antenna.
ii. Gain of the antenna.
iii. The Loss resistance (RL).
b. What are the parameters to be varied to increase the antenna gain at the same operating frequency.
