How Are Fields Created From Short Dipole / Oscillating Dipole? |
|
Answer» The dipole has two equal charges of opposite sign oscillating up and down in a harmonic motion. The charges will MOVE towards each other and ELECTRIC filed lines were created. When the charges MEET at the midpoint, the field lines cut each other and new field are created.This PROCESS is spontaneous and so more filed are created AROUND the antenna. This is how radiations are obtained from a short dipole. The dipole has two equal charges of opposite sign oscillating up and down in a harmonic motion.
