Abstract

When dealing with the synthesis sub-arrayed array antennas, the phase control, necessary for beam steering purposes, can be also exploited to reduce the undesired secondary lobes caused by the periodic spatial distribution of the amplitude excitations on the aperture when contiguous and identical subarrays are used. In order to determine the phase values of the array elements for a fixed sub-array amplitude weighting, the iterative projection method is adopted. Some representative results are shown to assess the effectiveness of the method. (c) 2009 IEEE. Personal use of this material is permitted.
