<p>A planar antenna radiating structure (30) comprising an array of continuous transverse stubs (11a) having a stepped configuration arranged in a ground plane (15) of a parallel-plate waveguide (12). Control of the complex reflection coefficient of the aperture of the radiating structure over a range of operating frequencies and scan angles is accomplished using parallel-plate waveguide modes through a choice of stub length(s), stub height(s), inter-stub spacings, parallel-plate separation and the properties of dielectric media used for the parallel-plate waveguide and stubs.</p> |
