Question

A signal is to be transmitted through a wave of wavelength λ , using a linear antenna. The length l of the antenna and effective power radiated P eff will be given, respectively, as- ( K is a constant of proportionality), λ 8 , P eff = K l λ, λ 16 , P eff = K l λ 3, λ 5 , P eff = K l λ 1 2, λ , P eff = K l λ 2

MARKS App · Accepted Answer

Length of antenna = comparable to λ Power P ∝ ( l λ ) 2 .
