Definition and Function of Electronic Antenna

　　With the development of the times, the Internet age is more and more widely used. Wireless is now a household name. Today, electronic antenna manufacturers take you to see the era of the network.

　　We know that communication, radar, navigation, broadcasting, television and other radio equipment are all through the radio wave to transmit information, need to have radio wave radiation and reception. In radio equipment, the device used to radiate and receive radio waves is called antenna. The antenna provides the required coupling between the transmitter or receiver and the medium that transmits radio waves. Antenna, like transmitter and receiver, is also an important part of radio equipment.

　　The antenna radiates and receives radio waves. However, it is not radio waves that transmitter sends to antenna through feeder. The receiving antenna can not send radio waves directly through feeder to receiver, which must go through energy conversion process. Next, we take the radio communication equipment as an example to analyze the signal transmission process, and then explain the energy conversion function of the antenna.

　　At the transmitter end, the modulated high frequency oscillating current (energy) generated by the transmitter is input into the transmitting antenna by the feeding device (feeding device can directly transmit current wave or electromagnetic wave depending on frequency and form). The transmitting antenna converts the high frequency current or guided wave (energy) into radio wave-free electromagnetic wave (energy) and radiates to the surrounding space.At the receiving end, the radio wave (energy) is transformed into high frequency current or guided wave (energy) through the receiving antenna and transmitted to the receiver by the feeding device. From the above process, it can be seen that the antenna is not only a device for radiating and receiving radio waves, but also an energy converter and an interface device between circuit and space.

　　Antenna is an indispensable part of our network signal, whether wired or wireless, it plays an important role. Interested partners in this area go to electronic antenna manufacturers to consult Xiaobian bar.
