Virtual insight into antenna design

What does your smartphone have in common with your car?

Convergentia is a company that specializes in simulation-aided design, which means that they use virtual technologies to simulate the future performance of antenna systems while the device is still very much a work-in-progress. Sounds high-tech? It is.

”Simulation is a great tool, because it allows us to test different design alternatives already in the very early stages of a development process,” Tatu Karvinen, Convergentia’s Business Development Manager describes.

“Simulating complex designs instead of taking the traditional prototype in a lab route cuts nicely into product development time and costs, because when you can verify the product’s functionalities and features on a computer screen, you don’t need do-overs in terms of prototype or test series. Tackling issues is easier, quicker and cheaper when the product still only exists in virtual form.”

Simulation-aided design also makes it possible to design extremely complex concepts like metal cover smartphones with complete cellular and non-cellular antenna systems. Different product versions can be concepted, tested and, if needed, discarded quickly, because once created, Convergentia’s simulation models are easily modified with whatever changes customer has made to the original design.

Especially well-suited for big and complex designs

Anywhere you have an antenna, you’ll find Convergentia’s designs. While portable electronics, like smartphones and tablet computers jump to mind, according to Tatu Karvinen, simulation-aided design is especially well-suited for the development of bigger, complex products that depend on reliable signal transfer and also have large and costly prototype series. Like medical equipment—or cars.

“From integrated multimedia systems to gps navigation, cars are full of intelligent technology that relies on fast and reliable data transfer,” Tatu Karvinen explains.

“And in the future, even more so. Intelligent safety systems and driving assistants, for example, depend on the accuracy and reliability of localisation data, and self-driving cars will take all that into a whole new level.”

The quality and reliability of an antenna design takes on a whole new meaning when your life can literally depend on it.
