Question

Wired Faculty App

What is the length of the dipole antenna to transmit signals of frequency 200 MHz?

Solution

The formula for

Length of dipole antenna = \frac{λ}{2}

Frequency of signal,

ν

= 200 MHz

Therefore,

Length of dipole antenn a = \frac{c}{2 v} = \frac{3 \times 10^{8}}{2 \times 200 \times 10^{6}} = 0.75 m .
