Simplifying the Antenna Design Process


Antennas don’t operate in isolation. They are the omnipresent link that makes wireless communication possible, and as use of applications ranging from radios and GPS to mobile phones and RFID increases, so too does the demand for high-performance antennas. Fitting wide-band and multi-band antennas into small devices requires careful antenna selection to find a design that gives both performance and compactness.

Put simply, successful antenna design should produce an element that is insensitive to manufacturing tolerances and is cost-effective to produce. Selecting the correct element as early in the design cycle as possible minimizes the risk of exceeding the budget or the time constraints experienced during later stages of the design and production process. This is why antenna design remains a growing area of interest for our customers - antenna simulation makes a huge difference in the design process.

Antenna Magus, an extensive antenna synthesis tool, has a database of over 200 antennas. The database can be explored to choose the optimal topology which can then be designed for specific criteria and exported to seamlessly integrate with the design workflow. Antenna Magus offers designers an unmatched combination of flexible design capabilities, concise and accessible information (including references to relevant literature and research resources) and exportable simulation models for CST MICROWAVE STUDIO®.

Aspiring to cover a broad range of antennas with information that enables engineers to consider various options with minimal time and effort, the use of Antenna Magus is valuable in various stages of the design process:
  • First order designs that have been validated against reference data are readily available, allowing the elementary and research steps at the start of the design process to be surpassed.
  • Using the ‘estimate performance’ feature, analysis can be carried out quickly, giving an indication of whether an element is suitable for the final design. Certain approximations can be made because of the known topology and environment of the antenna, which reduce the analysis time.
  • The information management system provides engineers with a framework to store and work upon information like documents, sketches, design algorithms, measure data and models. It can also be accessed by other team members for efficient knowledge-sharing.
With the demand for high-performance antennas increasing, antenna simulation seems to be the solution to not only simplify the antenna design process, but also improve accuracy, performance and costs. A trial version is available here to let you discover the benefits of Antenna Magus for yourself.
