In unequal conductor folded dipole, the diameter of the conductor of feed arm and the non feed arm are unequal.(a) True(b) FalseI got this question during an interview for a job.Question is taken from Folded Dipole Antenna topic in chapter Folded Dipole & Yagi – Uda Antenna of Antennas

Answer»

The correct ANSWER is (a) True

The explanation: In unequal conductor folded dipole, the diameters of the two conductors connecting TOGETHER are unequal. If the radii of two conductors are r1 (feed arm), r2 (NON feed arm) and SEPARATED by a distance, then the impedance transformation for folded dipole is given by

\(Z = Z’\LEFT(1+\frac{log⁡(\frac{a}{r1})}{log⁡(\frac{a}{r2})}\right)^2.\)
