Uncertainty Quantification Study for a Microstrip Patch Antenna
Application ID: 131781
In this tutorial, an uncertainty quantification analysis is performed on the Microstrip Patch Antenna model from the RF Module Application Library to explore how variations in input parameters, such as material properties or geometric variations, impact the antenna’s performance in terms of S-parameter. The analysis begins with a screening study to identify which parameters most significantly influence the key performance metrics. That is followed by sensitivity analysis to evaluate the relative effects of these parameters and their interactions. Next, uncertainties are propagated through the model to examine their influence on the distribution of the output characteristics. Finally, a reliability analysis is conducted to determine the probability of achieving the specific performance criteria. This comprehensive approach provides a detailed understanding of how parameter uncertainties affect the overall performance and reliability of the microstrip patch antenna.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
