An antenna is a Transducer that converts Radio Frequency (RF) Fields into alternating Modern-day or vice versa. There are both receiving and transmission antennas for sending or receiving radio transmissions. Antennas play an important Function in the operation of all radio sySTEM. They are utilized in Wireless Neighborhood Area Networks, mobile Telephony and satellite communique.
Antennas have an arRangement of Metallic conductors with an electrical connection to Receivers or Transmitters. Current is compelled via these conductors through radio transmitters to create alternating Magnetic Fields. These fields induce Voltage at the antenna Terminals, which can be connected to the receiver input. In the some distance area, the oscillating magnetic field is coupled with a comparable oscillating Electric Powered subject, which defines electromagnetic waves capable of propagating the Signal for long distances.
Radio waves are electromagnetic waves that convey signals thru air at the Velocity of light with none transmission loss. Antennas can be omni-directional, directional or arbitrary.
