RF Co-Site Interference Simulation in Complex Electromagnetic Environments

 

The world today is filled with radio frequency systems, sensors and wireless devices which make our lives easier, improve our communication with one another and ensure our safety and well-being. Preventing degradation or complete loss in the performance of these systems due to interference from other nearby systems is a well-known challenge. In recent years, it has received more and more attention as the challenge has increased due to the explosion of wireless systems we’ve come to rely on.

For military and defense, the challenge of co-site interference is crucial to address due to the increase in RF operational capabilities needed to perform a mission. Land vehicles, ships and aircrafts are extremely complex electromagnetic environments, with large numbers of electronic controls, antennas and sensors installed onboard. In aerospace, a reduced portion of the platform may be available for the antenna installation and placement due to mechanical and aerodynamic constraints, making the likelihood of an interference problem very high. ...

In this eSeminar, we will demonstrate how a 3D full-wave simulation can be used to analyze the antenna to antenna coupling for an Unmanned Aircraft System (UAS). The coupling data will then be used to estimate possible RF interference using one of the newer products of CST Studio Suite®: The Interference Task. With this new system-level tool, RF systems can be defined to analyze inter-system coupling. The analysis delivers the possible occurrence of RF interference at a glance. The interference task is fully integrated into the CST design environment, making it easy to run different scenarios and test mitigation strategies after the detection of possible interference.
