Engineering systems such as radio communication, broadcasting, television, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas. The antenna radiates radio waves and receives radio waves, however, the transmitter does not feed radio waves into the antenna through the feeder, nor does the receiving antenna feed radio waves directly into the receiver through the feeder, where energy conversion processes must be performed.
