There are various reasons why simulation and measurement may not agree, even when it seems like you’ve done everything right. These include the simulation set-up, manufacturing variations in the prototype, and the effect of connectors and cables used in the measurement. Therefore CST has teamed up with Rohde & Schwarz, the world’s leading manufacturer of wireless communications and EMC test and measurement equipment, to put together a workshop titled “Measurement meets Simulation” The aim of this workshop is to give engineers an insight into how to achieve accurate simulations and show best practice guidelines to getting better measurements.
The first workshop was held at Loughborough Antennas and Propagation Conference (LAPC) 2013 and attracted 40 participants, from both industry and academia. Participants learned how to design and simulate a patch antenna using CST STUDIO SUITE®, and how to measure its performance using the new ZNB and ZNC network analyzers from Rohde & Schwarz. In addition, they also learned about how under- and over-etching can affect the performance of prototypes, and how to estimate the effect of manufacturing tolerances using sensitivity analysis.

With the success of the first workshop, CST and Rohde & Schwarz are now bringing the workshop to other locations. The next workshop will be held in Dublin, Ireland on 9 July, 2014. If you are interested in attending, the agenda and registration details can be found on our website.
