Background

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, 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 reversible, i.e. the same pair of antennas can be used both as transmitting antennas and as receiving antennas, and the same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas, the antenna itself and the structure supporting the antenna. The correct structural design is necessary for the antenna to have the required electrical performance and to operate safely. The materials, structural form and sizes of all parts are properly selected to meet the electrical performance requirements; the antenna is light in weight, has sufficient strength and rigidity, can adapt to various environmental conditions, and is convenient to manufacture, transport and erect.
