🔴 ANTENNA || Communication System - Part 3 || in HINDI

In this Physics video lecture in Hindi for class 12 we explained the working of an antenna, basically dipole antenna. We considered the experiment conducted by Hertz to prove the existence of electromagnetic waves. Accelerated charged particles can create electromagnetic waves. As in oscillator charges move back and forth, an oscillator is a source of electromagnetic wave. When two colinear rods are attached to the LC oscillator they, as whole, work as a dipole antenna. Dipole antenna is known as Hertzian antenna. Similarly there can be a monopole antenna which is known as Marconi antenna.
