H-plane

The H-plane is a plane that contains the H-field and the direction of maximum radiation from the antenna. As an example, consider a short dipole, the magnetic fields are given by: This states that in the x-y plane, the H-fields are horizontally oriented (in the x-y plane). See Figure 1 below. Figure 1. Fields at a point along the y-axis from a short dipole. The fields at a point along the y-axis are shown in Figure 1. The E-field is oriented in the negative z-direction, the direction of propagation at the point is the +y-direction, and the H-field is oriented in the negative x-direction. The direction of maximum radiation is broadside from the antenna. The H-plane is any plane that contains the H-field and the direction of maximum radiation. Hence, the H-plane in this case is the x-y plane. See also E-plane.
