The antenna is the most important device in any transmitting station. Antennas are very commonly used for radio and television broadcasting. Also, antennas are used for dedicated point-to-point radio communication, radar, wireless LAN, space exploration, etc. An antenna is a logical arrangement of several conductors also called “elements”. An antenna also called an aerial is basically a transducer. The antenna is the device that sends a radio frequency (RF) signal through the space to the receiver.
