antenna beam width的意思|示意

Antenna beam width is a very important factor to consider when selecting an antenna. It is the angular measure between the half power points (3 dB points) of the antenna's radiated power which is measured in degrees of arc. In other words, it is the amount of space an antenna covers in a particular direction.

The beam width of an antenna is divided into two categories – horizontal and vertical. The horizontal beam width typically ranges from 10 degrees to 90 degrees, while the vertical beam width typically ranges from 1 degree to 60 degrees.

When selecting an antenna, it is important to consider the beam width of the antenna because it will determine the antenna's abilities. For example, an antenna with a narrower beam width is better suited for directional applications such as point-to-point links or directional Wi-Fi, while an antenna with a wider beam width is better suited for omnidirectional applications such as wireless local area networks (WLANs).

Another thing to consider is the gain of the antenna. The higher the gain of the antenna, the narrower the beam width will be. Antennas with higher gain are better suited for directional applications, while antennas with lower gain are better suited for omnidirectional applications.

In short, antenna beam width is an important factor to consider when selecting an antenna. It is important to consider the beam width of the antenna as well as its gain in order to ensure that the antenna is best suited for the application.
