Antennas can convert radio frequency signals transmitted from base stations into spatial electromagnetic wave energy, enabling electromagnetic waves to propagate into space and achieve long-distance transmission of information. This conversion process is the core of the antenna transmission function.
The receiving antenna is responsible for extracting electromagnetic wave energy from space, converting it into radio frequency signals, and then sending them to the base station for processing. In this way, the antenna can receive information transmitted from a distance and restore it to the original signal.
Antennas involve energy conversion during their operation. When launched, it converts electrical energy into electromagnetic energy; When receiving, it converts electromagnetic energy into electrical energy. This energy conversion function is the foundation for antennas to achieve information transmission.
