Question

A linear antenna having length less than λ/8 is called as _______

(a) Short monopole

(b) Short dipole

(c) Half-wave dipole

(d) Quarter-wave monopole

Answer 1

Right choice is (a) Short monopole

For explanation: Short monopoles have length less than λ/8 and the current distribution is triangular. Short dipole has length less than λ/2. Half-wave dipoles have length equal to λ/2. Quarter-wave monopoles have length equal to λ/4.
