Vehicle-mounted antenna simulation modeling method, device and equipment and storage medium

The invention provides an antenna simulation modeling method and device, equipment and a storage medium, and the method comprises the steps: building an antenna initial simulation model according to an antenna parameter, adding excitation to the antenna initial simulation model, and obtaining a scattering parameter; determining a matching circuit according to the scattering parameters, and associating the matching circuit with the antenna initial simulation model to obtain a to-be-verified antenna model; performing a simulation test on the to-be-verified antenna model, and comparing simulation test data with actual test data; if the error value is within the preset range, outputting the to-be-verified antenna model at the moment; and if the error value is outside the preset range, adjusting the matching circuit until the error value is within the preset range. According to the invention, the electrical performance parameters of the antenna model can be optimally designed, the impedance mismatch phenomenon is
