The performance of microwave and millimeter-wave antennas and circuits plays a key role in the application area of 5G, the internet of things (IoT), and satellite communication. The evaluation of such devices before fabrication and testing through electromagnetics simulation tools is beneficial to reduce the time and effort required in the design process during the development cycle.
In this session, you will see a live demonstration in the COMSOL Multiphysics® software showing how to set up and run a simulation to design and evaluate a grounded coplanar waveguide (GCPW) line with edge launch connectors. We will investigate the impact on the performance, such as loss per unit length of the circuit board by choosing different types of surface roughness models. The live demo also introduces a fast and efficient modeling workflow for time-domain reflectometry (TDR) analysis using fast Fourier transformation.
