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 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 transmitting antenna utilizes the property of the radiation field, so that the transmitted signals can be sufficiently radiated to the space after passing through the transmitting antenna. How is the conductor an effective radiator-conductor system? Here we first analyze the situation on the transmission line, and in order to transmit only energy without radiation on the transmission line of the parallel double lines, it must ensure that the two lines have symmetrical structure, the magnitude and direction of the current at the corresponding point on the line are opposite, and the distance between the two lines is less than pi. To effectively radiate the electromagnetic field, the symmetry of the transmission line must be broken, for example, by angularly separating the two conductors or by removing one of the conductors, so that the symmetry of the conductors is broken and radiation is generated.
The working state of the antenna to be measured in the antenna measurement can be a transmitting state or a receiving state. This can be flexibly selected according to the content of the measurement, the equipment of the measurement, the site conditions, and the like. From the antenna reciprocity principle it is known that the results of two operating states measuring the antenna parameters should be identical.
