An antenna is a transducer that transforms 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 used in a radio device to transmit or receive electromagnetic waves. Engineering systems such as radiocommunication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all use electromagnetic waves to transmit information, relying on antennas to work. In addition, non-signal energy radiation also requires an antenna in terms of transmitting energy using electromagnetic waves. The general antenna is reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna.

In recent years, the functions of terminal devices used to watch TV have become more and more popular around the world and their importance has been increasing. Major operators and TV stations have launched various TV program services that are suitable for receiving terminal devices, such as digital television broadcasting in Europe and America. Integrated digital broadcasting service, or China Mobile Multimedia Broadcasting in China. The frequency of TV signals is usually low frequency and wide frequency (such as CMMB (China Mobile Multimedia Broadcasting) operating bandwidth is 470-798MHz), because the length of the antenna and the frequency of the received signal In inverse proportion, in order to receive low frequency TV signals, TV antennas generally need to have a length of more than 120mm to achieve effective signal reception. At present, most of the terminal devices are TV antennas with a tie rod type, but the length and space occupied by the TV antenna cannot be greatly reduced due to the limitation of the frequency band of the received television signal.
