Abstract
Electromagnetic fields are generated from charge. These time-varying electromagnetic fields propagate in different directions of free space and radiate energy. This radiation of energy into the free space is accomplished efficiently with the help of a special electromagnetic device. This electromagnetic device is known as antenna. An antenna is an electromagnetic device that can transmit and receive radio waves efficiently. The antenna provides a transition between a guided electromagnetic wave and free space. The German physicist Heinrich Rudolf Hertz (1857–1894) first introduced the existence of electromagnetic waves, radiation of electromagnetic waves and antenna. Practical applications are ship navigation, aircrafts, air traffic control, satellites, radio and TV broadcasting.
