An antenna is a converter that converts the guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. In radio equipment, a component used to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same pair of antennas can be used as both transmitting and receiving antennas. The basic characteristic parameters of the same antenna for transmission or reception are the same. This is the reciprocity theorem of antennas.
