Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a directional high-gain antenna. Background Art

[0002] Antenna gain is used to measure the ability of an antenna to send and receive signals in a specific direction. It is one of the most important parameters for selecting base station antennas. Generally speaking, the improvement of gain mainly relies on reducing the beam width of the vertical radiation while maintaining omnidirectional radiation performance in the horizontal plane. Antenna gain is extremely important to the operating quality of mobile communication systems because it determines the signal level at the edge of the cell. Increasing the gain can increase the coverage of the network in a certain direction, or increase the gain margin within a certain range. In the existing environment, ordinary antennas generally cannot meet the higher gain requirements of the antenna, which will result in weak network signals, low rates, and intermittent network signals.
