The Ansys simulation process – HFSS software with SBR+ will solve the antenna's radiated far-fields and characterize its performance. Step 1 – Simulate the antenna's free-space performance with HFSS: ► Determine the radiation pattern (or antenna pattern or far-field pattern) ► Ensure the antenna will operate within the requirements of the base station ► Determine gain and directionality of the antenna ► Understand the frequency and bandwidth of the antenna Step 2 – Develop a model of the stadium and assign materials and boundaries: ► Metallic structures - Perfect E boundary assignments ► Absorbing materials - Fresnel (SBR+) boundary assignments ► Other material - Layered Impedance boundary assignments Step 3 – Place the antennas in desired locations within the stadium Step 4 – Convert the antenna radiation pattern into individual rays and using visual ray tracing with SBR+, note how those rays propagate through the environment and reflect or transmit off different materials. Each color represents the bounce number for a given ray and allows you to observe the RF propagation path. Step 5 – Identify locations of dense or underperforming signal strengths, make adjustments (change locations, add more antennas, or change the type of antennas), and simulate again. Repeat until you achieve sufficient coverage.
