Abstract Linear and 2-D phased arrays with wide-angle scanning   are expected, especially for low elevation target searching. Many efforts have been done to enlarge the scanning range. There are several methods to broaden the scanning coverage of array. In this presentation, we only focus on enlarging the beam-width of elements to improve the wide-angle scanning performance of array.
Pattern reconfigurable antenna, which increases beam-width equivalently, is used in a linear Vivaldi array for wide-angel scanning in time-domain. Element with Inherent wide beam is applied in linear and 2-D phased array to extend the scanning region.
