Answer / ravi durbha

First of all, any EM wave propagates through a medium with certain frequency and Antenna is a device which operates over band of frequencies. In most cases the dimension of the Antenna is governed by the longest operating wavelength.

Answer / chandra shekhar godiwal

Antenna Size -- lmda/4

lmda -- c/f

Antenna Size -- c/4f

Answer / ashish kashyap

Antenna dimension of EM wave depends on the range of
frequencies transmitted or received by the antenna.
So if we know the range of frequencies then
antenna size = 4*c*f
where c= velocity of light
f= lowest frequency of EM wave.
