A transverse electromagnetic wave with circular polarization is received by a dipole antenna due to polarization mismatch. The power transfer efficiency from the wave to the antenna is reduced to about
- A. 50%
- B. 35.5%
- C. 25%
- D. 0%
Answer: A. 50%
Explanation: A linear (dipole) antenna receiving a circularly polarised wave picks up only one linear component: 50 % (3 dB polarisation loss).
