Q. What is the input impedance to a lossless antenna, at resonance?
✅ Correct Answer: (C)
resistive
Explanation: in antenna impedance, impedance related the voltage and current at the input of the antenna. the real part of antenna impedance represents power that is either radiated away or absorbed within the antenna and the imaginary part of antenna impedance represents power that is stored in the near field of antenna. the input impedance of a lossless antenna is purely resistive.
