METHOD AND APPARATUS TO USE EMBEDDED PATTERNS AND S-PARAMETERS OF A SMALL PHASED ARRAY TO BUILD LARGE PHASED ARRAYS

Abstract:

To model a phased array antenna having a target array of antenna elements, a small array of antenna elements is selected that has fewer antenna elements than the target array. For each antenna element of the small array of antenna elements, far field patterns are captured for a plurality of signal frequencies. S-parameters for the small array of antenna elements are captured for the plurality of signal frequencies. The far field patterns captured for the antenna elements of the small array are mapped to antenna elements of the target array of antenna elements. The S-parameters captured for the small array are mapped to the target array.
