1. The antenna radiates and receives radio waves. However, it is not radio waves that the transmitter sends to the antenna through the feeder. The receiving antenna can not send radio waves directly through the feeder to the receiver, which must go through the 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.
2. At the transmitter end, the modulated high frequency oscillating current (energy) generated by the transmitter is fed into the transmitting antenna by the feeding device (the feeding device can transmit current wave or electromagnetic wave directly depending on the frequency and form). The transmitting antenna converts the high frequency current or guided wave (energy) into radio wave-free electromagnetic wave (energy) to the circumference. Circumferential radiation (see Figure 1); at the receiving end, radio waves (energy) are converted into high-frequency current or guided waves (energy) through the receiving antenna and transmitted to the receiver via 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.
