Periodic Boundary Conditions for Array Analysis

Calculate the far field pattern for a single element in an infinite two-dimensional array of pin-fed patch elements. The infinite patch array is modelled using periodic boundary condition. Calculate the approximated far field pattern for a 10x10 element array.

The mutual coupling between elements are taken into account when using periodic boundary condition to model an infinite array. If edge effects can be neglected, use the periodic boundary condition to model a large array accurately.

Tip: It is recommended to create the models in the order it is presented as each model uses its predecessor as a starting point. If you would like to keep the different models, save each model to a new location before starting a new sub example.
