Question

The dipole to which the power is applied directly from the feeder in the Yagi-Uda antenna is called as _____

(a) Director

(b) Reflector

(c) Driven element

(d) Boom

This question was posed to me by my college director while I was bunking the class.

My doubt stems from Yagi in division Folded Dipole & Yagi – Uda Antenna of Antennas

Answer 1

Right answer is (c) Driven element

For explanation I would say: The dipole to which the power is applied directly from the feeder in the Yagi-Uda antenna is called driven element. Directors add the field of the driven element and will excite the next parasitic element. Reflectors will increase the directivity of antenna.
