Chapter 14: Problem 17
Consider a lossless half-wave dipole in free space, with radiation resistance, \(R_{\mathrm{rad}}=73\) ohms, and maximum directivity \(D_{\max }=1.64\). If the antenna carries a 1-A current amplitude, \((a)\) how much total power (in watts) is radiated? \((b)\) How much power is intercepted by a \(1-\mathrm{m}^{2}\) aperture situated at distance \(r=1 \mathrm{~km}\) away? The aperture is on the equatorial plane and squarely faces the antenna. Assume uniform power density over the aperture.
