Background

Radio Frequency (RF) is an abbreviation for radio frequency, which represents an electromagnetic frequency that can radiate into space, ranging from 300KHz to 300 GHz. The short term Radio Frequency (RF) is radio frequency current, which is a short term for high frequency Alternating Current (AC) variable electromagnetic wave. Alternating current that changes less than 1000 times per second is called low frequency current, and alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current. Radio frequency technology is mainly used in wireless communication products, such as network base stations, mobile phones, notebooks and other products, in the theory of electronics, current flows through conductors, and magnetic fields are formed around the conductors; an alternating current passes through a conductor, around which an alternating electromagnetic field, called an electromagnetic wave, is formed. When the frequency of the electromagnetic waves is lower than 100khz, the electromagnetic waves can be absorbed by the earth surface and cannot form effective transmission, but when the frequency of the electromagnetic waves is higher than 100khz, the electromagnetic waves can be transmitted in the air and reflected by an ionosphere at the outer edge of the atmosphere to form long-distance transmission capability, and the high-frequency electromagnetic waves with the long-distance transmission capability are called radio frequency; radio frequency technology is widely used in the field of wireless communications.
