Huada fiberglass antenna is a component in satellite TV line electrical equipment that radiates or receives electromagnetic waves (the receiver only receives but does not produce radiation). Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc. rely on antennas to transmit information using electromagnetic waves. In addition, when using electromagnetic waves to transmit energy, non signal energy radiation also requires antennas. Generally, antennas have reversibility, meaning that the same pair of antennas can be used as both transmitting and receiving antennas. The basic characteristic parameters for transmitting or receiving on the same line are the same. This is the reciprocity theorem of antennas.
Antennas are classified from different perspectives:
① According to their nature of work, they can be divided into transmitting antennas and receiving antennas.
② According to their usage, they can be divided into communication antennas, broadcasting antennas, television antennas, radar antennas, etc.
③ According to the working wavelength, it can be divided into ultra long wave antennas, long wave antennas, medium wave antennas, short wave antennas, ultra short wave antennas, microwave antennas, etc.
④ According to their structural form and working principle, they can be divided into line antennas and surface antennas. The characteristic parameters of an antenna include pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization, and bandwidth. At present, the development of antennas has basically met the needs of various wireless transmission services. In certain special applications such as remote sensing, space communication, etc., with the continuous improvement of antenna theory, antenna types will continue to develop.
