Optenni has announced a new integrated workflow between ANSYS® HFSS and Optenni Lab for designing matching circuits for antennas and RF components based on 3D models simulated with HFSS. This integration is made possible by the new ANSYS® Electronics Desktop™ technology included with HFSS. It enables a new paradigm for electronic design with highly productive drag and drop dynamic links between electromagnetic field extraction and circuit simulation for easy problem set-up and reliable performance.
An important challenge in the daily work of antenna design engineers is to ensure that technical specifications are met for antenna impedance bandwidth and efficiency. These characteristics can be made faster and easier using matching circuits rather than by modifying the antenna’s geometry. Traditionally, designing matching circuits has required special expertise in the areas of impedance matching and circuit simulation tools.
Using a single macro command, impedance results from ANSYS HFSS simulations can be transferred to Optenni Lab for matching circuit generation and other analyses of the simulated impedances. Optenni Lab provides fully automatic matching circuit generation and optimization routines. The user needs to specify only the desired frequency ranges and number of components in the matching circuit after which Optenni Lab provides a choice of optimized matching circuit topologies. Optenni Lab features an intuitive graphical user interface, a comprehensive set of component libraries from leading component manufacturers, fast tolerance analysis and simultaneous multiport matching.
In the new workflow, matching circuits optimized in Optenni Lab can be easily returned to a circuit simulation schematic under the ANSYS Electronics Desktop framework, using a dynamic link to the HFSS simulation model. Thus, it is easy to design a matching circuit in Optenni Lab based on HFSS simulations and co-simulate the matching circuit and the electromagnetic structure on the ANSYS side.
