Figure 1 demonstrates one typical application of CMA to calculate the modes on a GSM-900 PIFA antenna.įigure 1 The first four modes on a GSM-900 PIFA antenna calculated with CMA. This allows engineers to tune the antenna to the correct frequencies and determine where to place the feed to couple into a particular radiating mode. For example, CMA can be used on a patch antenna to identify the resonant frequencies of the patch. For this reason, the release of CST STUDIO SUITE 2016 builds on the success of previous versions with a range of new features that make the analysis of systems more powerful while building on CST’s reputation for accuracy.Ĭharacteristic Mode Analysis (CMA) is a technique developed to provide physical insight into the behavior of a conducting surface by calculating the current-modes that it can support.

By replacing physical prototypes with virtual ones, engineers can study how their products work at the earliest stages of design and reduce the number of physical models that need to be constructed.įor virtual prototyping to be a viable option, the simulation tools need to be accurate without sacrificing performance.

It is used in industries as diverse as electronics, automotive, aerospace, medical and energy, and covers the electromagnetic spectrum from statics to optics. CST ® STUDIO SUITE ® is an electromagnetic simulation tool used to design, analyze and optimize devices and systems at all stages of the development process.
