+86 13961529027The RF signal power output by the radio transmitter is transmitted to the antenna through the feeder (cable) and radiated by the antenna in the form of electromagnetic wave. After the electromagnetic wave reaches the receiving place, it is followed by the antenna (only receives a small part of the power) and sent to the radio receiver through the feeder. It can be seen that antenna is an important radio equipment for transmitting and receiving electromagnetic waves. Without antenna, there will be no radio communication. There are many kinds of antennas for different frequencies, different purposes, different occasions, different requirements and other different situations. For many kinds of antennas, appropriate classification is necessary: according to the purpose classification, it can be divided into communication antenna, TV antenna, radar antenna, etc; According to the working frequency band, it can be divided into short wave antenna, ultrashort wave antenna, microwave antenna, etc; According to the directional classification, it can be divided into omnidirectional antenna, directional antenna, etc; According to the shape classification, it can be divided into linear antenna, planar antenna, etc; Wait, classification.
