Abstract
A theoretical investigation shows that, by using array elements operating at two or more azimuthal modes with circular polarization, the element patterns can be shaped and scanned. The beam shaping reduces the grating lobe effects and enhances the array gain for large scan angles. As an application of these elements in a phased array, the case of a circular seven-element array is investigated.<>
