Question 2 (a) A free-space 1 GHz circuit consist of a transmitting antenna with a 25 dB gain and a receiving antenna with a 20 dB gain. The transmitting antenna input is 150 W. The gain is with respect to a lossless isotropic source. What is the maximum power received at a distance of 0.5 km? C3/CLO1/PL01 (10 marks) (b) A magnetic field strength of 10 uA/m is required at a point o 90° and 5 km from an antenna in air. Neglecting ohmic loss, evaluate the power required to be transmitted using a Hertzian dipole of length N25. C5/CLO1/PL01 (10 marks) (c) A wave traveling normally out of the page has two electric field components and How would you categorize the wave polarization? C4/CLO1/PL01 (5 marks)
