Validation of Phased Array Mutual Coupling Simulation with Analytical Calculation

We validate our use of CST Microwave Studio for the analysis of a large, phased array by evaluating array parameters of a simple two-dipole array with an analytical model and CST. An analytical approximation of the mutual coupling and element impedance is compared with the results from the simulation software. The agreement between analytical and modelled results gives us confidence we are using the modelling software correctly and interpreting the results correctly. Using the impedance or scattering matrix for the array in this way will allow us to perform an analysis with LNAs using network theory separately from the full wave electromagnetic simulation software.
