Convergentia, a virtual prototyping specialist, replaced multiple hardware prototype cycles with 3D electromagnetic simulation using CST Studio Suite. The study details modeling of antenna matching networks, grounding structures, and material properties for LTE, Wi-Fi, and GPS antennas in thin consumer devices. Accurate correlation between simulation and measurement enabled faster design validation and reduced development time.

Key takeaways

CST Studio Suite enabled virtual prototyping that reduced physical prototype rounds for multi-antenna portable devices.

Accurate modeling of PCB layout, grounding structures, and material properties was required to achieve simulation-measurement correlation.

Field visualization in simulation identified lossy resonances and grounding issues that are difficult to diagnose in physical prototypes.

Combined antenna and layout simulation eliminated separate PCB design iterations and shortened antenna tuning cycles.

Virtual build workflow allowed parallel testing of EMC and throughput while antenna performance was validated in simulation.
