Fidelity factor and group delay simulation


I am simulating a custom antenna for the Decawave 1000 using CST Microwave Studio. The farfield and reflection coefficient simulation is finished and successful so far, but now I would like to check what the fidelity factor and groupd delay look like, since these are very important factors of an UWB indoor positioning antenna.

In your WB001 HARDWARE BUILD INSTRUCTION, section 4.5 you show results from group delay simulation and in section 4.6 there are also results for fidellity factor simulations.

I kindly ask you to explaind step by step how you have generated the plots in the mentioned sections, such that I can do so with my own antenna and compare the results.

Thank you very much!
Kind regards,
