Displacement Currents

Kirchhoff's current law as boundaries.

Displacement current explains why the ends of dipole antennas have something more than zero current.

Of fields and feedpoints

Understanding how feed position along the half-wave dipole antenna affects the electric and magnetic fields around it.
