- 2. INTRODUCTION An antenna is an electrical device which converts electric currents into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter applies an oscillating radio frequency electric current to the antennas terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).

Editor's Notes
- #5: Helical antennas are used because they are circularly polarized. This means that they radiate in both the vertical and horizontal directions, unlike the dipole which only radiates normal to its axis. Horn antennas are obviously very directional. The shape of the horn determines if the electric or magnetic fields are maximized. The gain is very high in the direction of the horns axis.
- #6: We will talk about kind of the antenna which is RHOMBIC ANTENNA
