[0002] An antenna is a transducer that converts guided waves propagating along a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems that utilize electromagnetic waves to transmit information, such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all rely on antennas. For example, listening to the radio in a car requires a radio antenna.
