E,H field directions

hi all
in my design i used a lumped port for dipole antenna.my doubt is, direction of E,H fields.i think E-field direction is same as the integration line direction.plz help me asap.what is the direction of H-field and direction of wave.iam radating the antenna in free space.

E,H field directions

near the antenna, the e-field is in general as the axis of the dipole and the h-field is in the phi-direction. but as you move further, this is not the case. they slowly change into spherical symmetry with the e and h fields perpendicular to the spherical r-coordinate.
i think the integration line gives the desired direction of the voltage/electric field/current at that plane.
