Hello, This is regarding CST simulation of antenna arrays with radome using Time domain solver. I am currently trying to solve a model having antenna arrays and radome. When looking at the far field radiation pattern results, an extra major lobe in the simulated far field pattern is appeared when compared to the measurement and our in house code analysis. (where measurement and in house code results agrees well and do not have this extra major lobe). Any suggestions on why this extra major lobe appears would be really helpful.
Many thanks.
