Can i simulate coil in ADS or HFSS etc. Is there any example available for ADS momentum. Is it possible to beam forming using coil arrays? Regards

EM simulation is possible and useful, planar simulation with ADS Momentum is a good starting point. A former collegue designed this using CST: https://patents.google.com/patent/DE102012101443A1/zh

I guess you are talking about coils for near-field applications. Both ADS Momentum and HFSS can help for the coil design, though the former should be faster and easier in this case.
