Description

5G base station antenna

Technical Field

The invention relates to a 5G base station antenna.

Background

In the engineering design of mobile communication network, the base station antenna should be reasonably selected according to the actual conditions of network coverage requirement, traffic distribution, interference rejection requirement, network service quality and the like.

In the engineering design of mobile communication network, the base station antenna should be reasonably selected according to the actual conditions of network coverage requirement, traffic distribution, interference rejection requirement, network service quality and the like. Since the selection of the antenna type is closely related to the terrain, the ground features and the traffic distribution, the antenna use environment can be roughly divided into five types, namely urban areas, dense urban areas, suburbs, rural areas, traffic trunks and the like. 1. Urban base station antenna urban base station density is higher, and single station anticipated coverage is less, should consider following several aspects when selecting the base station antenna:

(1) to reduce interference, antennas with horizontal half power angles close to 60 degrees should be used. The radiation pattern formed by the antenna is close to an ideal clover-type honeycomb structure, has good adaptability with the existing network, and is beneficial to controlling handover.

(2) Urban base stations generally do not require extensive coverage, but rather focus on the depth of the coverage. The effective vertical beam of the medium gain antenna is wider than that of the high gain antenna, the effective depth coverage range in the coverage radius is larger, the indoor coverage effect can be improved, and therefore the medium gain antenna is better to select.

(3) Because the urban base station antenna installation space is often limited, it is practical to select a dual-polarized antenna.

In summary, the urban base station preferably uses a medium-gain dual-polarized antenna with a horizontal half-power angle of about 60 degrees. For example a 15dBi dual polarized antenna with a 65 degree horizontal half power angle.

However, the actual application needs to be adjusted according to the actual situation, and the theoretical data may have a deviation in the actual application.

Therefore, when the antenna is actually installed, the radiation angle of the antenna needs to be reasonably adjusted, signal coverage is increased for the area with personnel activity, signal coverage is reduced for the area without personnel activity, and the effective power of the base station is reasonably utilized.

Therefore, the 5G base station antenna capable of adjusting the angle is designed.
