(Q). Paraboloidal reflector has a diameter D=20m and is designed to operate at f=6 GHz with an illumination efficiency η= 0.54. What is the antenna gain in decibels?
by 0 The effective area = πd^2*η = π*10^2*0.54 = 54 and Wavelength, λ = 3*10^8/(6*10^4) = 0.05 m Now, the gain of the reflector antenna is …
