(ANN), Random Forest, XG boost, K nearest neighbor (KNN), and Knowledge-based neural
network (KBNN) are used for efficient optimization of dielectric resonator antenna (DRA). ML
models are used to predict the| S11| for a particular set of frequency, resonator height,
aperture radius, and resonator radius. Finally, a comparative performance analysis of
different ML algorithms has been done with the outcomes of the HFSS EM simulator. Error …
