A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted.
Electrical Characteristics:
Antenna is a kind of converter, which transforms the guided wave transmitted by transmission line into electromagnetic wave propagating in unbounded medium (usually free space), or vice versa. In radio equipment, a component used to transmit or receive electromagnetic waves. Radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems, which use electromagnetic waves to transmit information, all rely on the antenna to work. In addition, in the aspect of energy transmission by electromagnetic wave, the energy radiation of non signal also needs antenna. Generally, antennas are reversible, that is, the same antenna can be used as both transmitting antenna and receiving antenna. The basic characteristic parameters of the same antenna are the same. This is the reciprocity theorem of antennas.
