Description

Technical Field

[0002] High gain antenna (English: High gain antenna) is relatively narrower in radiation direction, and the radiation in certain directions is more concentrated, so the energy is concentrated in certain directions, which is reflected as gain in certain directions. The difference between high gain antenna and ordinary antenna is that high gain antenna has higher gain and can be farther, but sacrifices the beam width; ordinary antenna has lower gain and closer distance, but the beam width, that is, the coverage range is larger. A typical example is a satellite antenna, which has a high gain, but is almost only effective in the front, with a very small angle. The base station directional antenna can cover a range of 120 degrees.
