The object of the invention is to provide the capability of synthesizing desired radiation patterns for dielectric antennas without the need for any metallization on the radiating surface. The frequency scanned dielectric antenna according to the present invention provides for sidelobe control by varying the slot conductance along the length of the antenna through the process of varying the slot width or slot depth, or both. By varying the slot conductance, and hence the amount of energy that each slot contributes to the beam pattern in the far field, lower sidelobe levels are achieved. Author
