Current Structure on a Half-wave Dipole — Lesson 2

This lesson discusses the current structure that forms on a half-wave dipole driven by a sinusoidal source, which is approximately sinusoidal. When the antenna is driven at exactly the half-wave frequency, the current magnitude forms a standing half-sinusoid along the length of the dipole, with nulls at either end of the dipole and a maximum at the center.
