Comparison of electromagnetic solvers for antennas mounted on vehicles

[摘要] An electromagnetic solver comparison for various use cases of antennasmounted on vehicles is presented. For this purpose, several modelingapproaches, called transient, frequency and integral solver, including thefeatures fast resonant method and autoregressive filter, offered by CST MWS,are investigated. The solvers and methods are compared for a roof antennaitself, a simplified vehicle, a roof including a panorama window and acombination of antenna and vehicle. With these examples, the influence ofdifferent materials, data formats and parameters such as size and complexityare investigated. Also, the necessary configurations for the mesh and thesolvers are described.
