2.4 GHz Directional Antennas
2.4GHz WiFi directional antenna: A directional WiFi antenna focuses the signal on a narrow signal opening angle and generates a high power gain through the bundling. Generally speaking, the smaller the opening angle of the WiFi directional antenna, the higher the transmission power. Directional antennas are used for point-to-point or point-to-multipoint links.
In principle, the higher the power gain of an antenna (expressed in dBi), the higher the range of the antenna. The smaller the signal opening angle, the more concentrated it is.
