The following information is about Antenna.
Antenna Defined
Antenna or aerial, a system of wires or other conductors used to transmit or receive radio or other electromagnetic waves ( Radio; Television). In a transmitting antenna, the signal from an Electrical Circuit causes electrons in the antenna to oscillate; these moving electric charges generate Electromagnetic Radiation, which is then transmitted through space. The distribution pattern of the transmitted wave depends on the design of the antenna; radio broadcast-station antennas are frequently designed to emit waves in all directions, whereas those used for Radar and for certain communication systems focus the waves in a single direction. In a receiving antenna, electromagnetic waves cause the electrons in the antenna to oscillate, inducing a signal that can be detected by an electric circuit. In general, a longer antenna is used to transmit or receive signals of longer wavelengths. Theoretically, the same antenna can be used both for sending and for receiving signals, but in practice, transmitting antennas are constructed to handle higher power loads than receiving antennas.
