Many design concepts and potentially thousands of subtle design space investigations can be explored is a short time. In the RF domain, rapid prototyping of concepts is critical to understanding wireless performance. Since antenna design can be impacted by even the smallest mechanical change in wearables, being able to rapidly iterate with the interdisciplinary team is critical. Simulation allows the antenna designer to stay in step with the design team, providing virtually immediate feedback on proposed changes. In short, HFSS is the key RF tool to develop the best possible product in the shortest amount of time.
General Purpose? or Application Specific? Technical limitations still make VR hardware cost-prohibitive for many, so careful consideration of the application and market must be applied very early in the development process.
