The method of co-simulation of electromagnetics and circuit takes advantage of high accuracy of electromagnetics and the speed of circuit analysis while designing any electrical component or system. This video provides a step by step guide on how to perform a co-simulation using a patch antenna model with Ansys HFSS and Circuit. The patch antenna element is widely used in 5G antenna arrays.
