Growing trends in developing thinner smartphones and tablets combined with the broad frequency of 4G, have made meeting required CTIA Wireless Association over-the-air (OTA) and SAR levels more challenging. FEKO’s comprehensive approach of Modeling, Simulation and Optimization presents engineers with the required tools to tackle wireless antenna design. Parametric modelling enables the user to build and change the design geometry to facilitate early prototype conceptualization. Fast, accurate solvers provide insight into the initial design performance. The Optimization platform is ideal for automated modification of the geometry to meet user specified goals (i. e. performance assessment early in the design cycle).
