The evolution to 5G promises low latency, high data rates, and increased channel capacity for mobile communication networks. Delivering this promise requires revamping existing networks, building new infrastructure and developing the client devices. These are major changes and implementing them is going to be difficult, costly, and time-consuming. To this end, virtual prototyping through simulation can help solve the difficult engineering challenges, realize innovations, and reduce costs. This paper provides pervasive simulation techniques and workflows for designing 5G antennas, microcell arrays and end-user devices or user equipment (UE) on Ansys tools.
