The function and classification of communication antenna

Antennas are an important part of wireless communication. What are the working principles and functions of antennas? There are many types of antennas. What are the main classification methods?

The working principle of the antenna: converts high-frequency current into electromagnetic waves when transmitting; converts electromagnetic waves into high-frequency current when receiving.

The function of the antenna: radiate and receive radio waves.

Antenna classification method: According to the purpose, it can be divided into base station antenna (base station antenna) and mobile station antenna (mobile portable antennas); according to the working frequency band can be divided into ultra-long wave, long wave, medium wave, short wave, ultra short wave and microwave; The direction can be divided into omnidirectional and directional antennas.

Through the introduction of the working principle and function of the above antenna, and the detailed explanation of the antenna classification, I believe that many people have a basic understanding of communication antennas. If you don't know how to choose an antenna, you can consult the manufacturer of NiceRF.
