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.
