(Q). A paraboloid reflector antenna with a diameter of 20m is designed to operate at a frequency of 6GHz and illumination efficiency of 0.54. Calculate the antenna gain in decibels.

D = 20 and r = 10 m, f= 6GHz k = 0.54 λ = 3*10^8/(6*10^9) = 0.05 Now, Antenna gain GP = 4π*k*A/ λ^2 = …

(Q). While measuring the gain of a horn antenna the gain oscillator was set for 10GHz frequency and attenuation inserted was found to be 8.9dB. Calculate the gain of horn, the distance between two horns was 45 cm.

8.9 dB = 10log(Pt /Pr ) Pt /Pr = 7.76 Pr/ Pt = 1/7.76 = 0.1288 Given, r = 0.45 m λ = 3*10^8/(10*10^9) = …
