Hertzian Dipole

A Hertzian dipole is a simple model used in physics and engineering to describe how tiny, idealized antennas emit radio waves. It consists of two very short, opposite electric charges or currents separated by a small distance. When these currents oscillate, they produce electromagnetic waves that radiate outward in space. This model helps us understand the fundamental behavior of antennas and how they transmit signals, serving as a foundation for designing real-world communication devices like radios, televisions, and wireless networks.
