Chapter 14: Problem 9
A dipole antenna in free space has a linear current distribution with zero current at each end, and with peak current \(I_{0}\) at the enter. If the length \(d\) is \(0.02 \lambda\), what value of \(I_{0}\) is required to \((a)\) provide a radiation-field amplitude of \(100 \mathrm{mV} / \mathrm{m}\) at a distance of \(1 \mathrm{mi}\), at \(\theta=90^{\circ} ;(b)\) radiate a total power of \(1 \mathrm{~W} ?\)
