Repeat Problem 14.17, but with a full-wave antenna (2ℓ = λ). Numerical integrals may be necessary.

Consider a lossless half-wave dipole in free space, with radiation resistance, R_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-m² aperture situated at distance r = 1 km away? The aperture is on the equatorial plane and squarely faces the antenna. Assume uniform power density over the aperture.
