According to theoretical study of radiation from a same linear antenna, the power radiated is proportional to \([\lambda=\) wavelength \(]\)
- A \(\lambda^{-2}\)
- B \(\lambda^{-1}\)
- C \(\lambda^{2}\)
- D \(\lambda\)
Answer & Solution
Correct Answer
(A) \(\lambda^{-2}\)
Step-by-step Solution
Detailed explanation
A linear antenna radiates power proportional to \(\left(\frac{1}{\lambda}\right)^{2}\).
Hence a longer antenna emits more power. Also power radiated by a long wavelength base would be small.
Hence a longer antenna emits more power. Also power radiated by a long wavelength base would be small.
