Vedclass · Answer

(C) The physical size of an antenna,such as a dipole antenna,is typically related to the wavelength $\lambda$ of the signal being transmitted or received. Since the wavelength $\lambda$ is given by $\lambda = c/f$,where $c$ is the speed of light and $f$ is the carrier frequency,the length of the antenna $L$ is proportional to $\lambda$ (e.g.,$L = \lambda/2$ or $L = \lambda/4$). Therefore,$L \propto 1/f$. This implies that the physical size of the transmitter and receiver antenna is inversely proportional to the carrier frequency.
