Asymmetrically flared notch radiator.

摘要

An asymmetrical notch radiating element (20) comprises a metal or metal-clad dielectric substrate (21) into which a tapered slot (22) or notch (22) is disposed. The direction of the axis of the tapered slot (22) lies along any preselected axis and is not constrained to be collinear with the normal to the aperture of the element (20). An asymmetrical antenna array (27) comprises a plurality of asymmetrical notch radiating elements (20) as described above. Each of the plurality of radiating elements (20) is disposed such that the apertures (25) of each of the elements (20) are substantially coplanar and are at an angle relative to the notch axis. The present antenna uses asymmetric slot lines to control the antenna's electrical performance. The precise slot dimensions are chosen to optimize radiation and reduce scattering. <IMAGE>
