Question

An antenna behaves as resonant circuit only when its length is
(a) $\frac{\lambda}{2}$
(b) $\frac{\lambda}{4}$
(c) λ
(d) $\frac{\lambda}{2} \hspace{3} or \hspace{3} integral \hspace{3} multiple \hspace{3} of \hspace{3} \frac{\lambda}{2}$

Answer 1

hey mate!!! maybe ur ans is (a)

Answer 2

An antenna behaves as resonant circuit only when the alternating current will have it's resonant frequencies and that is possible only when the Wavelength is divided by an integral multiple of 2.
