The Asymptotic Solver can simulate extremely large platforms such as aircraft, ships, and buildings very efficiently, making it well suited to many kinds of antenna placement scenarios. The ray-tracing Asymptotic Solver in CST STUDIO SUITE can now directly calculate the coupling between antennas. The Interference Task shows at a glance which combinations of RF systems can potentially lead to co-site interference problems, allowing mitigation approaches tobe tested on a virtual prototype.
The Interference Task offers a straight forward approach for investigating potential EMI issues using coupling data from simulations. Coupling matrix extraction with FD3D offers an efficient way to fine-tune 3D filter structures. The complex and sensitive nature of these filters makes them challenging to design and tune with traditional methods. The tool Filter Designer 3D (FD3D) can automatically synthesise cross-coupled and diplexer filter designs to meet the specifications, including transmission zeroes, Q-factor,and equiripple.
