What Is Antenna And How It Works?
An antenna is a device that receives electric signal or electric power and then operates and converts it into radio waves. How the antenna works, the answer can be describe as follows. An antennas purpose and work is to receive enough of the transmitted electromagnetic waves to supply an electrical signal level sufficient for the receiver to operate and process the signal into useful audio and video.
Signals have sources such as radio waves are electromagnetic fields emitted from manmade source or natural source like lightning strike and arcing brushes of electric motor when it is in running condition respectively.
While discussing about antennas the concept of a signal should be cleared. Signal has strength and power. It is common practice to hear that radio stations advertise their antenna tower like 10Mega watts, that mean that this station offering a better approach of signal than that of a station that advertises 1Mega watt of radiated power.
Antennas operate with many features that are the terms of electromagnetic field theory concept and in this technology era the simple physics subjects uses commonly these terms. They are frequency, wavelength and gain of antennas signal. It depends on the size of antenna that how far will be your signal could transmit or receive from the required point or position. Antennas are major components of all equipment that uses radio technology. They are used in systems such as radio broadcasting, broadcast television and satellite communications.
It is impossible in todays technology that receiver could receive enough of the satellite signal with a 1_inch antenna. Power levels for transmitting stations are limited by regulation and in the case of satellites are also limited by the physics of the available power supply. So, multiband antennas mean antennas with multi frequencies of any sort are used.
By designing antenna to work well with the vast differences in bandwidth, improvements can be made to radio broadcast reception over great distances requires a receiver with a port for accepting an external antenna and an outdoor antennas.
Lets explain slightly to the radio waves and antennas. Radio waves basically are electromagnetic waves which carry signals through the air, space or any sort of medium through which the signal could be able to transmit. In air and space the signal transmits at the speed of light with almost no transmission loss. Any sort of radio that includes receiver or transmitter always requires antenna because, the procedure and its working corresponds and depends on fields that must be establish for the transmission or at the receiving end. So, antennas are also used to couple its electrical connection to the electromagnetic field.
