Pattern synthesis usually involves determining the strengths of the currents in a given array so that it radiates a specified pattern. Demonstrating that this pattern can be produced by an actual array of physical elements is the next step in the synthesis problem. This entails determining the excitations needed for a physical array when mutual interactions are accounted for. These excitations can be either source voltages or the synthesized currents themselves, with both options available in NEC 4 (the Numerical Electromagnetics Code). While this is done here using NEC, the same approach could use any wire-antenna computer code. When the current option is chosen, the code first solves for the voltages that induce the required currents. This is a simple procedure that automatically includes the effect of mutual coupling among the array elements. The purpose of this article is to examine how well a numerical model of a given array will match the specified pattern. Several examples of this approach are included here to demonstrate the process.
