Not sure what the H field direction would be at either the toroid or the
antenna.
The antenna is working in the near field of the coil that contains a
supposition of normal (probagating) EM waves such that most of the H fields
cancel leaving a large H field.
So its hard to say what direction the H filed is from simply knowing what
the E field is.
The whole near far field/impedance thing was discussed adnorsium in
connection the power transmission thing.
Its does not do much plane wave detecting so its misleading to call it a
plane wave antenna. I more accurate term would be a capacitive probe.
I agree it very unlikely that anything more than a sheet of copper is
required anymore so than the plates of a capacitor.
