Antenna Theory

✴In radio and electronics, an antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa.✴

►An Antenna can be used either as a transmitting antenna or a receiving antenna.✦

►A transmitting antenna is one, which converts electrical signals into electromagnetic waves and radiates them.✦

►A receiving antenna is one, which converts electromagnetic waves from the received beam into electrical signals.✦

►In two-way communication, the same antenna can be used for both transmission and reception.✦

►Antenna can also be termed as an Aerial. Plural of it is, antennae or antennas. Nowadays, antennas have undergone many changes, in accordance with their size and shape. There are many types of antennas depending upon their wide variety of applications.✦
