The document discusses different types of antennas and their applications. It specifically focuses on the rhombic antenna, describing its structure as four wires connected in a rhombic shape and terminated by a resistor. Rhombic antennas are mounted horizontally and placed above half the wavelength from the ground. They have advantages for long distance communication, high frequency transmission and reception, and point to point communication.

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).
