How do we reduce wind load in base station antennas?
To reduce wind load in base station antenna designs, the key is to delay flow separation and reduce wake. This equation can be simplified, as only the third term on each side is related to pressure drag. Furthermore, force is related to pressure: How do we reduce wind load for base station antennas?
How do base stations use energy?
Since base stations are major consumers of cellular networks energy with significant contribution to operational expenditures, powering base stations sites using the energy of wind, sun, fuel cells or a combination gain mobile operators’ attention.
How does wind direction affect base station antennas?
In the world of base station antennas, wind direction is unpredictable. Therefore, we must consider 360 degrees of wind load. Wind force on an object is complex, with drag force being the key component. Drag can be pressure drag, friction drag and/or vortex drag. Pressure drag is usually the most dominant force.
Does Andrew wind load reducing end caps improve free-end flow?
The CFD simulation, as shown in Figure 8, demonstrates the impact difference between a “normal” end cap and one with Andrew wind load reducing end caps. The aerodynamic profile delays separation of the end flow and therefore promotes eficient free-end flow.
Which wind direction should be considered in a base station antenna?
In aerospace and automotive industries, only unidirectional wind in the frontal direction is of concern. In the world of base station antennas, wind direction is unpredictable. Therefore, we must consider 360 degrees of wind load. Wind force on an object is complex, with drag force being the key component.
How do enhanced antenna designs reduce wind load?
In the basic formula above, at any given wind speed, the key variable is drag coeficient, Cd. Andrew’s enhanced antenna designs focus on lowering Cd. Using a thorough understanding of the physics and aerodynamics behind wind load, we optimize the antenna design to minimize wind load.
