ENHANCEMENT OF PHASED ARRAY SIZE AND RADIATION PROPERTIES USING STAGGERED ARRAY CONFIGURATIONS

By A. A. Eldek

Abstract:
In this paper, two staggered array configurations are presented for enhancing size and radiation properties of wideband phased array systems. The proposed arrays are obtained either by rotating each element 45° or by inserting additional rows in the middle which are shifted by half the distance between elements. These two configurations allow for a smaller distance between array elements (29% less), while the actual distance between elements in the diagonal direction is kept the same. Reducing the distance between elements results in eliminating/reducing the grating lobes in a wider frequency range, which improves the array usable bandwidth. In addition, this proposed array produces better gain and maximum steering angle.
