## (8.1)

{:.question}
Find the electric field for an infinitesimal dipole radiator.

## (8.2)

{:.question}
What is the magnitude of the Poynting vector at a distance of 1 km from an antenna radiating 1 kW of
power, assuming that it is an isotropic radiator with a wavelength much less than 1 km? What is the
peak electric field strength at that distance?

## (8.3)

{:.question}
For what value of $$R_\text{load}$$ is the maximum power delivered to the load in Figure 8.3?

## (8.4)

{:.question}
For an infinitesimal dipole antenna, what are the gain and the area, and what is their ratio?
