What is the input impedance of a half wave folded dipole?

(a) 73Ω

(b) 292Ω

(c) 146Ω

(d) 36.5Ω

The question was asked by my school principal while I was bunking the class.

This intriguing question originated from Folded Dipole Antenna in section Folded Dipole & Yagi – Uda Antenna of Antennas

Correct choice is (b) 292Ω

The explanation is: The input impedance of a half wave folded dipole is four times the half wave dipole.

So Z= 4×73=292Ω
