Figure 2-1. Induction Field about an Antenna
2-7. The graph shown in figure 2-2 shows the relationship between the
magnetic (H) field and the electric (E) field plotted against time. Note that
the two fields are 90 degrees out of phase with each other. If you compare the
graph in figure 2-2 with figure 2-1, you will notice that the two fields around
the antenna are displaced 90 degrees from each other in space. (The H field
exists in a plane perpendicular to the antenna. The E field exists in a plane
parallel with the antenna, as shown in figure 2-1.)
