RF directional antenna refers to an antenna that transmits and receives electromagnetic waves in one or several specific directions with particularly strong electromagnetic waves, while transmitting and receiving electromagnetic waves in other directions is zero or very small. The purpose of using directional transmitting antennas is to increase the effective utilization rate of radiated power and increase confidentiality; The main purpose of using directional receiving antennas is to enhance signal strength and increase anti-interference ability.Directional antennas are commonly used to cover long streets and have the following advantages:
1. It has a large forward gain
2. It can suppress the backward signal, which is very useful when the cell will cause potential interference to the cell behind it.
It is also worth mentioning that directional antennas can improve indoor coverage in certain buildings within the coverage area of small cells.
The antenna has different radiation or reception capabilities for different directions of space, which is the directivity of the antenna. Depending on the directionality, the antenna has two types: directional and omnidirectional.
Directional antenna
RF directional antenna, on the horizontal pattern, appear as a certain angular range of radiation, which is commonly known as directionality. As with omnidirectional antennas, the smaller the lobe width, the greater the gain. Directional antennas are generally used in communication systems in environments with long communication distance, small coverage, high target density and high frequency utilization.
