Question

Which of the following will add the field of the driven element and will excite the next parasitic element to increase the gain of the antenna?

(a) Director

(b) Reflector

(c) Active element

(d) Boom

I got this question in a national level competition.

My question comes from Yagi topic in portion Folded Dipole & Yagi – Uda Antenna of Antennas

Answer 1

Right option is (a) Director

For explanation I would say: Directors add the field of the driven element and will excite the next parasitic element. Directors will increase the gain of the antenna in the forward direction. Reflectors will add fields of the driven element in the direction from reflector to driven element.
