Question

Which of the following statement is not correct?

(a) Folded dipole antenna has less impedance than half dipole

(b) Folded dipole is a balanced antenna

(c) Folded dipole antenna is a dipole antenna with its end folded back forming a loop

(d) Balun is used at the feeder when unbalanced feed is used in the folded dipole

I got this question during an online exam.

My doubt is from Folded Dipole Antenna topic in portion Folded Dipole & Yagi – Uda Antenna of Antennas

Answer 1

Correct choice is (a) Folded dipole antenna has less impedance than half dipole

Best explanation: The impedance of folded dipole is four times the impedance of the half dipole. So its impedance is higher than the half dipole. Since folded dipole is a balanced antenna we use a balanced feeder so Balun is used.
