Abstract
A `four-square element` phased array antenna structure and associated feed network laminate architecture has a linear physical geometry of multiple trimmed four-square antenna elements disposed on a thin dielectric support layer, which facilitates compactly placing multiple linear arrays in a highly spatially densified side-by-side arrangement. This allows for placement of a greater number of antenna elements in a direction orthogonal to the array than in the longitudinal dimension of the array, so that the frequency of operation of an overall array can be increased relative to that of a conventional four-square architecture, thereby improving bandwidth coverage. For a linearly polarized beam, the trimmed four-square array of the invention enjoys a frequency response that is equal to or better than that of a conventional non-trimmed four-square architecture.
