Power radiated by an antenna is directly proportional to (l – length of antenna, λ – wavelength of electromagnetic wave) |
\(\left(\frac{l}{λ}\right)^{2}\) \(\frac{l}{λ}\) \(\left(\frac{λ}{l}\right)^{2}\) \(\frac{λ}{l}\) |
\(\left(\frac{l}{λ}\right)^{2}\) |
Power radiated by antenna is \( P_r=\frac{\mu_0 \pi^2 I_0^2 l^2}{\lambda^2} \) Then, \( P_r \propto\left(\frac{l}{\lambda}\right)^2 \) |
