Antenna Placement Simulation using Ansys HFSS SBR+
Application areas like 5G and radar systems often require the simulation of antenna placement on large vehicles and buildings. This is usually a challenging task due to the geometry size versus wavelength tradeoffs and the complexity of the model geometry. Asymptotic solvers are known to be a solution for these applications. In this webinar, the highly accurate shooting and bouncing ray (SBR+) method within Ansys HFSS will be presented as an advanced solution. A live demonstration will spotlight how it can be combined in a hybrid simulation approach with finite-element boundary integral (FEBI) domains or reading in far-field or near-field sources. Additionally, key post-processing capabilities and recommended solver settings will be discussed.
Ansys HFSS SBR+
ANSYS HFSS SBR+ is an asymptotic high-frequency electromagnetic (EM) simulator for modeling EM interaction in electrically large environments. It employs the shooting and bouncing ray (SBR) technique for rapid computation of EM solutions. HFSS SBR+ computes installed antenna performance, extended near-field distributions, far-field radiation patterns and radar signatures for electrically large platforms with minimum computational resources.
Isolated antenna simulations from ANSYS HFSS can be used in hybrid HFSS SBR+ simulations to assess the antenna interaction with its host and environment. HFSS SBR+ extends the SBR method by overlaying advanced diffraction physics such as physical theory of diffraction (PTD), uniform theory of diffraction (UTD) and creeping wave (CW) physics for enhanced fidelity. Multicore CPU, message passing interface (MPI) and graphic processing unit (GPU) acceleration features enable significant analysis time reduction.
