Why is radio frequency important?（2）

In this sense, we need varying voltages and currents. The key to this propagation phenomenon is the self-sustaining relationship between the electromagnetic components of electromagnetic radiation. A changing electric field produces a magnetic field, and a changing magnetic field produces an electric field. This mutual regeneration manifests itself as a unique entity, namely electromagnetic waves. Once generated, this wave will propagate outward from its source, advancing at the speed of light to the unknown depths day after day.

Electromagnetic radiation is actually very simple, as mentioned above, as long as there is a changing electric and magnetic field, electromagnetic waves can be generated. In a circuit, any changing current/voltage will produce electromagnetic radiation, even digital signals are no exception. In most cases, these electromagnetic radiations only generate noise. If there is no interference to the communication system, we can completely ignore it. But once there is interference to the communication system, it becomes electromagnetic interference EMI, and we need to find ways to filter it out. We have seen that RF design is not just about generating EMR; on the contrary, RF design is the art and science of generating, manipulating, and interpreting EMR, which allows you to reliably transmit meaningful information between two circuits that are not directly electrically connected.

To a certain extent, the design of any wireless system is to find ways to generate electromagnetic radiation and control useful electromagnetic radiation. This useful electromagnetic radiation constitutes the basis of wireless wireless, and it is also our RF research and design. Object.
