Question 3 [12 marks] The power radiated, Prad, by a lossless antenna is 10 W. The directional characteristics of the antenna are represented by the radiation intensity of U = B, cos'e W/sr where 0 SOS0 SØS2 (0 and are the elevation and azimuth angles respectively) (a) Determine the constant Bo. [3 marks] (b) Determine the directivity of the antenna in dB. [3 marks] (c) Find the gain of the antenna in dB. [3 marks] (d) Calculate the maximum power density at 1000 m from the antenna. [3 marks]
